A Power-Efficient and Social-Aware Relay Selection Method for Multi-Hop D2D Communications
Bidi Ying, Amiya R. Nayak · IEEE Communications Letters · 2018
Due to the short communication range, users are selected as relays to support multi-hop transmission for content sharing/downloading in D2D communications. In this letter, we first exploit social relationships from interacts and contributions, and then formulate an optimal relay selection problem to enhance cooperative multi-hop D2D communications. A Power-efficient and Social-aware Relay Selection (PSRS) algorithm is provided to solve the above problem. Simulation results show that our method has the lowest average power consumption compared to the existing methods.
