SELECTED PAPERS FROM IEEE/CIC ICCC 2017

The IEEE/CIC International Conference on Communication in China (ICCC) has been globally recognized as one of the important annual international conference held by the IEEE Communication Society(ComSoc) and China Institute of Communication (CIC)in China. The sixth IEEE/CIC ICCC 2017 was held in the magnificent city of Qingdao, China, 22-24 October,2017. In particular, IEEE/CIC ICCC 2017 aims at addressing a key theme on “Communications for Everything”, which broadly covers all disciplines of communications from fundamental research to emerging applications. The technical program of ICCC 2017 features 4 world-class keynote speeches, 9 technical symposiums,8 tutorials, 2 industrial and academic panels, and 2 workshops. In addition, there are 17 invited talks delivered by 17 famous experts from both academia and industry.ICCC 2017 successfully brought together distinguished scholars and leading researchers to discuss the latest advances in information and communication technologies,where the participants had a very fruitful and productive conference, and also an unforgettable stay in Qingdao.

In this sixth edition of IEEE ComSoc’s fl agship conference in China, we have maintained the high quality of the conference. We received 471 paper submissions from 24 countries and regions. Out of these, 222 papers were accepted and 213 papers were included in the fi nal program, corresponding to an acceptance rate of 47%.All the papers were carefully peer reviewed by about 450 TPC members and reviewers, with each paper evaluated by at least three reviewers.

Among all there paper presented in the conference, we selected a limited number of excellent ones and invited the authors to submit their extended versions to this Feature Topics of China Communications. The extended papers contain at least 30% material variation and the guest editors assigned another around of reviews for each one.Based on the review results, we eventually selected the following nine papers for this Feature Topic.

The 1st article, “User Association and Backhaul Bandwidth Allocation for 5G Heterogeneous Networks in the Millimeter-Wave Band” is authored by Zhenxiang Su, et al. and its original conference version received the Best Paper Award in ICCC 2017. In this paper, the authors focused on the user association and the wireless backhaul bandwidth allocation for a two-tier heterogeneous network (HetNet) in the millimeter wave (mmWave) band,with the purpose of maximizing the sum rate of the system. To achieve that, the closed-form expression of sum logarithmic user rate is established according to the result of multi-user MIMO downlink employing zero forcing beam forming. Based on that, a distributed algorithm was proposed, with which the optimal backhaul bandwidth allocation factor and user association variables can be obtained to maximize the sum rate.

The 2nd article, “Privacy-Preserving Prepayment Based Power Request and Trading in Smart Grid”, is authored by Shaohua Li, et al. This paper aims at dealing with utility loss due to the mismatch between the users’power request and demands in smart grid. To do so, a novel power request and trading scheme was proposed by adopting the prepayment mechanism, where the dynamic demands of the users can be satisfied and the grid efficiency can also be improved. In addition, two security protocols, which can protect individual privacy from the malicious adversary or semi-trust grid utilities, are also developed for control center and the gateway.

The 3rd article, “Outage Performance of Cognitive DF Relaying Networks Employing SWIPT”, is authored by Jing Yang, et al. This work provides a comprehensive study on the outage performance of cognitive relay networks with simultaneous wireless information and power transfer (SWIPT) over Nakagami-m channels. With the help of bivariate Meijer’s G-function, the close-form expressions on the outage probabilities of the system with decode and forward (DF) as well as incremental decode and forward (IDF) protocols are derived. Numerical results are also provided to verify the theoretical analysis.

The 4th article, “Semi-Supervised Learning Based Big Data-Driven Anomaly Detection in Mobile Wireless Networks”, is authored by Bilal Hussain, et al. In this paper, a novel semi-supervised statistical-based anomaly detection scheme was proposed under the concept of machine learning and big data. The purpose is to improve the overall network performance by fully exploring the knowledge hidden in the ever-increasing data generated in LTE networks. The proposed algorithm is capable to track and analyze the spatiotemporal information on hourly basis and marks the anomaly occurred in a particular region of the networks. Hence it can help cellular network operator to reducing the OPEX and utilize the resources in a dynamic and more efficient way.

The 5th article, “5.9 GHz Vehicular Channels Comparisons Between Two Traffic Status for Dense Urban Area”, is authored by Fang Li, et al. This paper focuses on the characteristics of vehicle-to-vehicle (V2V) radio channel at 5.9 GHz. The comparative investigation is performed in the same region but different traffic density and speeds, which can be classified into the congestion and non-congestion cases. To do so the continuous measurement campaign is conducted on a city expressway through the complex dense urban area in Wuhan, China.With the measured parameters, this work concludes that the cumulative distribution function of root mean square delay spreads and root mean square Doppler spreads in the non-congested scenario and congested scenario were all fit well with Lognormal distribution. Different intensities of traffic and speed of vehicles has major impact on the root mean square Doppler spreads and level crossing rate. It also reported that the V2V channel characteristics for urban areas in China big city are different from the previous measured results under similar scenarios in Europe.

The 6th article, “Context-Oriented Multi-RAT User Association and Resource Allocation with Triple Decision in 5G Heterogeneous Networks”, is authored by Jing Li, et al. This paper proposes a joint multiple Radio Access Technologies (RAT) user association and resource allocation strategy with triple decision and integrated context awareness of users and networks. A dynamic game based ant colony algorithm (GACA) is designed to simultaneously maximize the system utility and the fairness of resource allocation. Simulation results show that it is more reasonable to make multi-RAT association decision from a system-wide viewpoint than from an individual one. Compared to max-SNR based and ABC based strategies, the proposed method alleviates network congestion and optimizes resource allocation.The proposed algorithm obtains 39%～ 70% performance improvements.

The 7th article, “Channel Estimation and Throughput Evaluation for 5G Wireless Communication Systems in Various Scenarios on High Speed Railways”, is authored by Yanrong Zhao, et al. This paper evaluates the downlink throughput of 5G High Speed Railway (HSR) communication systems on three typical scenarios including urban, cutting and viaduct with three different channel estimators. The channel parameters of each scenario are generated with tapped delay line (TDL) models through ray-tracing simulations. In addition, a novel channel estimator, namely historical information based basis expansion model (HiBEM) is proposed in this paper. The performance of the HiBEM estimator is analyzed in terms of mean square error (MSE). The system throughput with different channel estimates is evaluated and compared over each scenario. The comparison study shows that the proposed HiBEM outperforms other estimators and that the system throughput can reach the highest point in the viaduct scenario.

The 8th article, “Fake Reviews Tell No Tales? Dissecting Click Farming in Content-Generated Social Networks”, is authored by Neng Li et al. This paper focuses on the detection of click farming in the content-generated social networks (CGSNs). To achieve that, a three phase detection method is proposed. In such a method, the communities are first clustered based on newly-defined collusion networks. Then the Louvain community detection method is applied to detecting communities. The binary classification on detected-communities is finally performed to verify the click farming. This work shows its importance by revealing some interesting results.For example, the prevalence of click farming is different across CGSNs, most click farmers are lowly-rated,click-farming communities have relatively tight relations between users, and more highly-ranked stores have a greater portion of fake reviews.

The 9th article, “Cluster-Based Content Download and Forwarding Scheme for Highway VANETs”, is authored by Mingsi Zhang, et al. This work aims at increasing the data download volume in the dark area of Highway VANETs. To achieve that, a novel cluster-based scheme is proposed by combining both clustering strategy and the carry-and-forward algorithm. The basic idea is to coordinate the cooperation of multiple infrastructures,cluster formation in the same direction and data forwarding of reverse vehicles to facilitate the target vehicle to download large-size content. Through combining microscopic and macroscopic mobility models, simulations is performed to evaluate the performance of the proposed scheme in terms of data download volume and throughput. The results have shown that the proposed scheme outperforms other content download schemes for highway VANETs in terms of total data download volume.The research in this paper shed insight into the design of cooperative communication scheme to maximize the utilization of bene fi ts in dark area to extend the limited RSU’s coverage and short contact time between RSU and the tagged vehicle.
