| Abstract: | In order to select the relay node efficiently and energy-saving for D2D communication, we combine energy harvesting technology and D2D technology, build a D2D homogenous cell model based on energy harvesting, and propose a relay selection algorithm based on energy collection. Using energy harvesting technology to provide relay energy, the node is avoided from communication interruption or selection relay failure due to its low residual energy. Energy harvesting power and channel conditions are analyzed in the physical domain, and the appropriate relay in the alternative relay set is selected by the communication two-end node inspired by the human social campaign mechanism, so as to avoid the interruption of the entire communication caused by the relay meeting only one node requirement. The simulation results show that the algorithm proposed in this paper improves the probability of relay selection success, equipment survival time and system throughput compared with the prestige-based relay selection algorithm. |
