Device-to-device communications in underlay mode has emerged as a promising way to enhance spectrum efficiency in cellular networks. Recently, relay selection in D2D communications underlaying cellular networks is gaining more research interest. In this paper, we propose two relay selection schemes for D2D communications underlaying cellular networks, Midpoint Relay Selection using Social Trust and Battery Level (MRS-ST-BL) and Midpoint Relay Selection using Social Distance and Battery Level (MRS-SD-BL). These proposed schemes utilize battery power level information of devices together with social trust information of users in the network for relay selection. For performance evaluation, initially we show that the throughput of state-of-the-art schemes Hybrid Relay Selection (HRS) and our previously proposed schemes Midpoint Relay Selection using Social Trust (MRS-ST) and Midpoint Relay Selection Using Social Distance (MRS-SD) decrease, when relays have varying battery power. Then, we compare the performance of our proposed schemes against existing schemes including HRS, MRS-ST and MRS-SD. The performance comparison is done at various social trust scenarios and device densities. We show that our proposed schemes can significantly improve the throughput of D2D communications, particularly when relays have different battery power levels in weak social trust scenarios. Finally, we show that the performance of our proposed scheme MRS-ST-BL varies with the change in battery power threshold.

Due to the development of mobile transmission techniques, more exciting services can be launched that may change our daily lives in more easy and comfortable ways. The introduction of device-to-device (D2D) service in future 5G communication systems can extend the service coverage of intelligent medical treatment from hospitals to anywhere inside the network coverage area, which can save precious time and medical resources. As one of the key techniques in a 5G system, D2D technology has attracted extensive attention from academia and industry due to its system performance improvement, user experience enhancement and service extension. However, the introduction of D2D service will tremendously pollute the system transmission environment due to the induced interference, especially in the downlink direction where the interferer is very strong. This situation brings new challenges for effective and green resource utilization. To solve this problem, a green spectrum resource allocation strategy based on the Hungarian method is proposed in this paper to optimize system spectrum efficiency while considering the fairness among users under the assumption that all resources are fully shared by traditional cellular and newly introduced D2D users. To validate the performance of the proposed algorithm, a system-level Monte Carlo simulation is also conducted, which shows the favorable performance of the proposed algorithm over the traditional greedy algorithm. KEYWORDSD2D service, fairness, intelligent medical service, spectrum efficiency, 5G mobile network INTRODUCTIONWith the rapid development of mobile Internet services and the popularity of smart phones, the demand on high-speed data rate transmission will explode in the near future. Aside from the traditional service, with the aid of powerful smart phones and various sensors, some new areas have appeared such as an intelligent medical service, which requires high transmission rates and low latency for a high-resolution visual effect to assist in telemedicine diagnosis. However, the tight requirements for high-definition image and video transmission during diagnosis is very difficult to support by the traditional transmission method and radio resource management scheme. To solve this problem, the new device-to-device (D2D) communication method may become a powerful tool to help the current legacy transmission method. 1-3 In order to improve resource utilization, overall network performance and user experience, D2D technology based on point-to-point direct communication is adopted in the 5G mobile communication system. On the one hand, the application of D2D technology can simultaneously offload the base station traffic and provide high-speed data services for some application scenarios. On the other hand, terminal relay communication can be used to solve the problem of gaps in coverage to a certain extent. 4-7 As one of the key technologies in the 5G mobile communication system, D2D technology has the following advantages: (1) Data transmission between D2D users is no long...
