Abstract
In this paper, we proposed a joint optimal algorithm based on relay nodes selection and power allocation, which utilizes the theory utility maximization modeling system by adopting convex optimization, and obtains the optimal power allocation between source node and relay nodes by applying the Karush-Kuhn-Tucker (KKT) condition. In addition, the relay nodes allocated with power unequal to zero are the selected relay nodes, therefore, the selection of relay nodes is realized. Moreover, the optimal number of relay nodes is discussed. Simulation results show that the proposed algorithm achieves a better performance than the traditional equal power allocation algorithm.
