Abstract :
Based on the quadratic function relation between terminal battery energy consumption and transmission power, this paper introduces the relaying scheme of combining cellular networks and Ad Hoc user terminals to establish the single node model of relay selection mechanism, then an optimal relay selection scheme can be proposed constraint to the specific interrupt probability and power allocation. When part of the base stations are in sleep mode to contribute to save costs and energy consumption, the multi-hop nodes as cooperation relays can ensure the normal communication and realize the optimization of energy efficiency, thus saving the costs caused by a large number of fixed relays.
