摘要:Abstract: This paper introduces the optimal relay selection algorithm based on joint optimization function, and it applies the optimal power distribution mechanism which can allocate the source and relay power reasonably. Under condition that the total power is limited, the proposed optimal power distribution mechanism, compared with the equal power distribution mechanism, can make the power distribution more effective, and nodes in the network have a longer lifetime. The simulation results based on MATALAB show that the relay, which uses the optimal power distribution mechanism based on the joint optimization function, has a better performance.
