Abstract: In a wireless sensor network (WSN),data gathering is more effectually done with the clustering process.Clustering is a critical strategy for improving energy efficiency and extending the longevity of a network.Hierarchical modeling-based clustering is proposed to enhance energy efficiency where nodes that hold higher residual energy may be clustered to collect data and broadcast it to the base station.Moreover,existing approaches may not consider data redundancy while collecting data from adjacent nodes or overlapping nodes.Here,an improved clustering approach is anticipated to attain energy efficiency by implementing MapReduction for regulating mapping and reducing complexity in routing mechanisms for eliminating redundancy and overlapping.In order to optimize the network performance,this work considers intelligent behaviors’to adapt with network changes and to introduce computational intelligence ability.In the proposed research,improved teaching learning based optimization is used to evaluate the coordinates of target nodes and nodes upgradation for determining energy consumption.Node upgradation is performed by integrating Map reduction to attain modification in Hop size of nodes.This variation reduces communication complexities.Therefore,network lifetime is increased,and redundancy is reduced.While comparing with existing approaches here,sleep and wake-up nodes are considered for data transmission.The proposed algorithm clearly demonstrates 50%,16% &12% improvement in nodes lifetime,residual energy and throughput respectively compared to other models.Also it shows progressive improvement in reducing average waiting time,average queuing time and average energy utilization as 30%,20% and 46% respectively.Simulation has been done in NS-2 environment for distributed heterogeneous networks.

1 Introduction

Wireless Sensor Networks (WSN) gathers information of data locality among nodes via constant monitoring and prominently used in wide area network (WAN) as it is extremely cheaper and route establishment procedure is also considered to be simpler.WSN is used for monitoring military tracking,fire,temperature and so on [1].WSN is used for the short range that helps in monitoring environmental factors [2].Sensor node [SN] design is based on parameters like energy constraints,restricted computation and storage capacities like collaborating sensors in performing measures [3].The sensor controls over harsh environment leads to control over placed sensors with hectic confronts (Fig.1).In every routing protocols of WSN,application functionality may change with variations in goal [4].The functionality of WSN is based on the battery functionality of SNs as battery-based sensors that are accountable for network lifetime [5].Similarly,clustering is a technique that deals with SNs energy consumption for forming groups termed as clusters,with individual Cluster Head’s (CH) [6].SNs comes under a single cluster and they involve themselves in broadcasting the data collected to CHs which is communicated to sink nodes either by single or multi-hop communication [7].

Figure 1:WSN architecture

WSN possesses huge amount of limitations like topology,energy and SNs’bandwidth to model a transmission protocol [8].With the idea for handling constraints,there are clusters based on a multi-hop algorithm.Some cluster based protocols includes low energy adaptive clustering hierarchy and Fuzzy C-means may fulfill superior network lifetime [9].The effectual solution for WSN energy efficiency lies over the network layer,routing protocol and path where lifetime and energy of network will be optimized.Energy optimization is one amongst the prime cause related to network lifetime,which is handled by various algorithms.Some investigators provide simpler assumptions towards sensors of homogeneous environment comprises node with the same energy with the ability for processing and sensing [10].In practical cases,various networks comprise heterogeneous sensors that have diverse features with changing modalities.Diversity in SN can improve network performance such as network lifetime [11].

The routing protocol selection is based on network resources and application requirements.Henceforth,modeling of routing protocol is based on improving network lifetime for higher time period with resource utilization available over the network more economically [12].Moreover,routing leads to huge challenges owing to restricted resource availability,limited energy and limited communication in SNs [13].Thus,routing is carried out with complexity related to communication overhead and routing which is relieved.WSN carries out two communication mode known as query-driven and event-driven routing protocols [14].The former model facilitates the node to request Base Station (BS) for collecting information regarding the present scenario.Similarly,the latter model is used for data transmission from SN to BS.Huge broadcast and multi-cast protocols are used in WSN routing.

This investigation aims to handle the crucial problems related to routing with optimization algorithm [15].With a multi-objective optimization algorithm,the anticipated model is designed to map the routing spectrum and reduce the complexity associated with routing.It works on various objectives like distance,energy,mobility,and delay and nodes lifetime [16].The anticipated hybrid optimization technique uses various constraints and performs certain functionality to the given optimal solution in cluster head formation.The hybridized model is mapping the route with Teaching task and reducing the complexity by learning the difficulties in route establishment.This is termed as MapReduction based Teaching Learning Optimization (MR-TLO).The main objective is to proved optimal solution for improving network lifetime.Data transmission will be initiated over network where transmission is followed for energy constraints during communication process based on CH mapping.The essential contribution of the anticipated model is:

· Initially,the complexities over route established by mapping and teaching process.Then,the constraints are reduced by reduction task and by learning task for further route optimization.This helps in scheduling the task properly for transmission and shows certain merits in determining effectual trade-off among them.Therefore,effectual communication is established.

· This work considers intelligent behaviors’to adopt with network changes and to introduce computational intelligence ability.Here,improved teaching learning based optimization is used to evaluate the target nodes coordinates and nodes upgradation for determining energy consumption.Node upgradation is performed by integrating Map reduction to attain modification in Hop size of nodes.

The remainder of this investigation is organized as: Section 2 with background knowledge over recent multi-objective functions and the factors related to it.Sections 3 &4 discusses in detail about mapping and reduction task by integrating Teaching-Learning Optimization.Section 5 depicts numerical values and analysis related to it.Section 6 shows the conclusion of the anticipated model and directions for further research.

Sitanavah et al.in [18],discusses about routing constraints in Multi-media WSNs for offering multi-objective approaches.It deals with Quality of Service[QoS] by handling delay and expected transmission count.QoS factors and single objective systems are optimized with traditional approximation and it will not determine the parametric nature that provides sub-optimal solutions.Some case studies determine appropriate improvements over QoS routing solutions.For instance,delay,approximated mean enhancement ratio for scenarios and time.Imran et al.in [19],depicted alliance functionality via multi-objective optimization for sensing coverage for enhances nodal coverage efficiency.This work offers a proportionate relationship for renovating energy functionality between the neighborhood and active nodes.This relationship is utilized for determining mobile nodes with lesser energy.Thus,energy stability with complete network and resources has to be maintained.The simulation outcomes validate that this model enhances network coverage quality,reduces node energy depletion more effectually.Therefore,it enhances network life cycle.

Hwang et al.in [20],utilized Multi-objective particle swarm optimization to anticipate a Multi-objective load balancing approach.Reliability and energy efficiency is measured as an objective function.With the appropriate residual energy of CH,energy efficiency is determined.Here,reliability is generated on inter-cluster routing based communication cost.Load balancing is performed with mixing up functionalities of next hop and CH in all iteration.Fuzzy based decision making is determined with a compromise solution for selecting nodes.The performance of anticipated and prevailing approaches has been analyzed based on energy efficiency,Packer Drop Ration (PDR),network lifetime,accuracy and number of active nodes.With all these parameters,coverage and scalability are chosen for quality evaluation provided with multi-objective optimization model.

The total amount of added relays are deployed for fulfilling every SN in the initial design model with k-length bounded vertex disjoint shortest paths to sink and paths to reduce the total amount of deployed relays.Fatih et al.in [22],attempted to analyze overlap encountered among communication ranges to reduce the minimal amount of added nodes required for k-connectivity repair.

In distributed actor based recovery model,the neighborhood node failure has to be replaced.The finest candidate selection is based on physical proximity and lowest node degree towards failure.Similarly,Senel et al.in [23],anticipated the least distance based movement recovery process where the direct neighborhood set of failed node moves from failed node position while original position is substituted with the nearest vertex actor.Borkar et al.in [24],anticipates an algorithm for constructing a complete graphic terminal and for evaluating minimal spanning tree utilizing the kruskal algorithm.This is constructed with tree edges.Some three step procedure for network segmentation through steiner tree approximation.Shah et al.[25] designed grid based area deployment for equal sized cells anticipating relay node placement algorithm.Here,bio-inspired relay node placement is anticipated.

Khabiri et al.in [26] utilized multi-objective connectivity factor for restoring network connectivity;however,it works back-ward with diverse partitioning to determine the bi-directional connection and to provide data to sink node.Here,segments are considered as SN collection and set apart from prevailing models.Thus,the modeling of WSN is considered to be more complicated with substantial aspects over various parameters like energy,delay,PDR,routing,cost and efficiency over real time application.Therefore,to enhance network lifetime this investigation uses a Multi-objective function integrated with MapReduction concept to identify the central information processing over WSN.

Data is handled by each node in distributed creation strategies,and decisions are made locally and are restricted to the node’s immediate vicinity (single-hop neighbors).The below are the key features of distributed networks:

· Self-contained devices are available.

· Each node communicates with its immediate vicinity.It is appropriate for distributed applications (multi-agent systems,self-organized systems,etc.)

· Much of the data is routed into a single node.

· Interconnection equipment (routers,bridges,and so on) are optional.

· Because of their adaptability,they can be used to target harsh conditions.

The complexity of the information forwarding mechanism necessitates the use of robust algorithms.The proposed work must ensure that complex activities are completed with equivalent results to centralized solutions.

3 Methodology

In the anticipated model,clustering and routing are considered as a major factor for analysis.Therefore,the hybridization approach known as MapReduction based Teaching-Learning optimization approach.This is designed by Rao,which is inspired based on Teacher’s influence and learner’s interaction.This model outperforms various Meta-heuristic approaches and compared with benchmark standards.This approach is hybridized into two phases.They are: Mapping based on Teacher’s influence and reduction with learner’s activeness.The flow diagram of proposed model is given in Fig.2.

Figure 2:Flow diagram of a proposed model

3.1 Teaching Phase

Based on various nature-inspired algorithms,Teaching-Learning Optimization (TLO) utilizes population solutions to the give global solution.Here,the initial population is set of learners and study materials are considered as design variables.Compute the entire population with ‘fitness function’best solution is considered as a teacher.Here,the teacher holds an influence towards shifting learners (mean) to knowledge level.Then,the set of new learners is evaluated with Eq.(1):

The difference among teacher and mean learners is provided as in Eq.(2):

where′M′is mean,Xteacheris teacher value,′r′is random number with a range of [0,1] andTFis teacher factor based random value decide with equal probability (either 1 or 2) as in Eq.(3):

3.2 Learner Model

Here,students attempt to enhance knowledge via interaction with one another.By forming a group of students,the level will be increased.Here,ithpopulation is chosen randomly by learnersXj;wherei/=j,then reviseXibased on Eq.(4):

To attain the beneficial factors form TLO,this work hybridizes the MapReduction for routing and scheduling data transmission.

3.3 MapReduction Phase

MapReduction is performed in computing clusters in various nodes.This cluster uses multilevel hierarchical network architecture.When a job enters into the network,it brings various random amounts of map tasks that have to be performed by machines.The incoming data will be of data chunks with fixed size and every chunk is replicated and placed in various locations.Here,tasks are allocated with clustered nodes.When the processing is launched,machine will not initiate till all the available chunk arrives.Here,this model is used for task scheduling and routing.This is termed as a co-operative scheduler.This is partitioned into two phases: allocate incoming tasks to network nodes or initiate network communication when tasks reach the cluster and route the task arrived for network communication.Initially,queuing architecture of the network model has to be determined.Every cluster node has to process the queue.The scheduler must keep track of the loading queue to buffer tasks for system allocation and assign data to machines for remote processing.Thus,tasks are ready for processing.

4 MR-TLO Model

It is generally known that WSN are strict towards energy constraints and possess limited energy replacement abilities.Therefore,it is essential to optimize energy consumption during routing;thus,it may prolong the network lifetime.Here,MR-TLO is not a centralized network model where the algorithm is subjected to work in every node.Here,the process is initiated with the population path and determines the optimum path for further transmission.The anticipated method uses TLBO for routing purpose.

4.1 Mapping Data

Source node has to transmit a message to neighbors where request raised has to ask for an available route to final destination.It has to choose the data chunks from various clustered nodes which may be lead to sink node.When the request is received and data are accumulated from various clustered nodes,it has to maintain routing table.When a route prevails,source node has to receive data directly.Else,the receiver has to request neighbors.This SN has to initiate population based on total paths to sink.Population path is specified asP={p1,...,pi,...,pm},where path is formed usingpi={ns,...,nk,...nsink}.

Population initialization is measured as a task carried out by set of nodes.For instance,the source has to identify events from request to neighbors.The neighbor has to validate the routing table,where the route towards sink was stored and informs the source.Else,it has to check the corresponding routing table when sink was stored and informs the source node.After a certain waiting time,all data chucks from various nodes are received by the source node;this may collects data and generates population by random number of paths.The waiting time during data chunk collection is deployed over the simulation environment.

When population is initiated,source node has to partition the raw data into pieces to handle bandwidth.This comprises of time and data,event identification regarding event detection(mapping events).Before establishing communication,every data is related to parameters.It has to identify the possible nodes based on the path towards sink and sequence number.When queuing time or waiting time considered for prolonged time,data chunk will be reduced,known as reducing task.

4.2 Executing MR-TLO

Here,routing problem is considered with various steps.Optimization parameter based initialization is used to resolve a Multi-objective function.The first process is population size which is based on the number of nodes over network queuing time.Nodes will wait initially for receiving any request from neighbors to paths from source to sink.This number is determined as population size.Next is termination criteria,when a path is revisited huge amount of time during various iterations,this is determined as solution.Accordingly,for evaluating objective function,solution may produce finest outcomes based on lifetime and energy consumption.Here,variables are considered to be in discrete form,i.e.,data chunks are determined to be discrete with the number of nodes over given path.Here,the energy function of WSN is determined with an approximate energy model.Energy is consumed during power transmission and reception.For transmitting certain bit to a remote location with distance ‘d’,transmitter consumes some energy as in Eq.(5):

Similarly,for receiving data the energy consumed is given below in Eq.(6):

When the transmission path is longer,energy consumed during transmission for′b′bits over the path is determined as in Eq.(7):

WhenEelec=,∈amp=100nJ/bit/m2are transmission energy and amplification;similarlyd2is square of Euclidean distance among node ‘i’and ‘i + 1’.L is spatially distributed nodes.Objective function model can balance energy consumption and transmission delay as in Eq.(8):

whereEminresidual energy of nodes with minimal residual energy is,Eavgis average residual energy andD(X)is delay in data transmission through path′X′.Similarly,population is determined as in Eq.(9):

Here,the path size is not essential,whereqiis path length with index′i′.The objective value is determined as in Eq.(10):

4.2.1 Teaching Based Node Mapping

Here,compute the mean of actively available nodes over the cluster where it cannot be provided analytically (number of paths).Hence,some mathematical operations have to be redefined using the mapping process.The node connectivity is mapped using an edge re-combination operator to model inherits of offspring with essential information from parental structures.Consider that the simulation setup for node connectivity is determined by 50 nodes,where the source has to identify the events.The node population is determined by mapping nodes connectivity from source to sink.

The population mean isXmean,the mapping is carried out among the paths from available populations (nodes).Teacher gives better optimal solution for all iterationXteacher=min1≤=i≤m(f (Xi)).Based on this,the generated solution is(S→32 →13 →7 →sink).The route is mapped from the source to sink with intermediate nodes like 32→13→7.The difference among the intermediate node is given as intersection between two paths as in Eq.(13):

With the difference,the new solution will be determined asXnew.Difference is the number of nodes that may be replaced with others in old solution to validate it.Xnewwill be accepted as an objective function superior thatXold.

4.2.2 Learning with Reduction

Here,choose randomXjfrom population wherei/=j.With discrete value,Xnew=operator.The termination process will be achieved when reduction process stops.Learning the routing path is achieved based on the queue waiting time,when transmission decision commences with′t′time slot and service commences after a data chunk arrival.In a queue scheme,each node retains a nominal waiting period for a data chunks to arrive at the transmitting node.The queue model is specified as in Eq.(14):

For every time slot,chunk that arrives to the system are allocated to a queue where total chunk arrival is specified asQm,i∈Qiwithm∈Miandi∈{0,1} is specified asA(t).Subsequent system arrivals are determined as interval arrivals that departs from other queuing system of nodes at last time slot.It is represented as in Eq.(15):

The transmission also considers bandwidth constraints,service process of queues in network is determined as follows:

The service process initiated with queuing process is specified asS(t).when node initiates transmission with task during time slot.The service is completed at every time slot and other nodes are considered to be idle for various time slots (t).The relations among internal and service are given as in Eq.(17):

The queue length is determined as vector as in Eq.(18):

This statistical assumption is performed during learning process with co-operative scheduler with queuing processZ(t),t ＞0.this state is measured when it reaches zero vectors.

4.2.3 Learning Operation

Node identifies a co-operative scheduling process for data transmission to sink with a solution attained from the learning process.When the node fails,the node which holds information constructs a new path using the teaching-learning process.When the task is completed,BS holds the received paths and generates raw data.When the packet is missed,the source receives warning message from the sink over the same path.Thereby,it will re-broadcast the missing packets and follows this procedure till the end.Data transmission from source to destination is attained and network capacities are optimized.To validate this,the routing protocol is performed.By computing the overall functionality,the algorithm model is designed as below.

The above mentioned process is carried out for routing in WSN with MR-TLO.Here,the population is initialized and the path has to be identified based on time to live process of nodes.The mean vector is determined with edge re-combination operator.The best solution has to be determined and the solution has to be validated with the maximal objective function.The node which is no longer alive will be terminated and also node that holds prolonged waiting time will also be terminated.

5 Numerical Results

The proposed routing model is implemented over NS-2 simulator with 64 bits OS.This experimentation is performed in a PC with Intel(R)i5 3.20 GHz and 4 GB RAM.The parameter settings are provided as in Tab.1.

Table 1:Simulation setup

To validate the performance of the proposed model in terms of efficiency,there are a number of metrics that is utilized for comparing the variations in the number of nodes,coverage and total packets.The energy consumption model encounters certain limitations such as energy level is set as 10 J for all nodes,network topology holds till 200 nodes with uniform distribution.To compute the efficiency of the anticipated routing protocol,consider certain conditions utilized for experimental and events occur in the same place and all packets are sent from source node.For generating a routing protocol,there are roughly about 1000 packets used for transmission.Average CPU time is given and it is measured based on number of nodes,random deployment and simulation region against sink.Nodes lifetime is determined based on initial battery energy and power with Eq.(19):

Based on packets received at sink,the anticipated model gives superior outcomes in various scenarios.Huge residual energy gives lesser cost (Tab.2).It specifies more energy compared to other models for transmitting packet size to sink node.The residual energy influences a longer network lifetime with maximal residual energy.It is proven that MR-TLO works superiorly while prolonging network lifetime than other routing model.While conducting certain experimentation,huge amount of packets are transferred from source to sink nodes.This model shows superior outcomes by extending network lifetime.

Table 2:Throughput

This work considers five different parameters like throughput,an average waiting time of data packets in the queue,average queuing time,average energy utilization and residual energy.This helps in determining the efficiency of routing model to improve network lifetime.Here,packets travel from source to sink,where packet consideration average varies from 50,100,150,200,300,400,500 and 600 respectively.The anticipated MR-TLO is compared with standard algorithms like Artificial Bee Colony Optimization (ABC),Particle Swarm Optimization (PSO) and Ant Colony Optimization (ACO) respectively.The throughput attained by MR-TLO is 89,90,94,110,115,130,145 and 150 respectively when packet size changes.MR-TLO shows an average waiting time of 1.80,3.00,3.15,3.80,4.25,4.50,5.5 and 6.5 ms for collecting data chunks from the nodes of a cluster (Tab.3).

Table 3:Average waiting time (ms)

Similarly,average queuing time is determined as 0.126,0.186,0.190,0.225,0.295,0.352,0.400 and 0.410 ms respectively (Tab.4).The energy utilization of nodes during data transmission is determined in Joules.During packet transmission the average energy consumed is 2.653,3.578,4.254,5.152,6.157,7.154,8.147 and 9.152 J respectively (Tab.5).Similarly the average residual energy after the completion of task is 75,85,98,112,126,132,142,154,160 and 165 J respectively (Tab.6).When the residual energy is higher it is directly proportional to the nodes lifetime.Nodes lifetime is increased when residual energy is higher.It is measured in seconds.

Table 4:Average queuing time

From nodes 10-100,nodes lifetime is determined as 20,26,35,46,50,64,72,89,98 and 110 s respectively (Tab.7).Fig.3 depicts the throughput of MR-TLO and other approaches like ABC,ACO and PSO.The throughput of MR-TLO is higher than other models.Fig.4 depicts the average waiting time (AWT) of MR-TLO and other approaches like ABC,ACO and PSO.The AWT of MR-TLO is lesser than other models.Fig.5 depicts the Average Queuing time (AQT)of MR-TLO and other approaches like ABC,ACO and PSO.The AQT of MR-TLO is lesser than other models.Fig.6 depicts the Average Energy utilization (AEU) of MR-TLO and other approaches like ABC,ACO and PSO.The AEU of MR-TLO is lesser than other models.Fig.7 depicts the residual energy of MR-TLO,ABC,ACO and PSO.Due to the structural framework of proposed model,the residual energy remains higher than other models.Fig.8 depicts the nodes lifetime.When residual energy is higher,nodes lifetime is also higher.
