This paper studies joint optimization strategy of relay selection and power allocation in a decoded forwarding (DF) protocol. The strategy first proposes a cooperative relay node selection algorithm based on residual energy (RE), and makes optimal relay node selection jointly considering the channel state information (CSI) and the residual energy information of nodes to optimize the network lifetime...
For optimizing the performance of cooperative communication system, it presents a multi-relay amplify forwarding (AF) and decoded forwarding (DF) cooperation node selection algorithm based on the residual energy, considering jointly the residual energy information of nodes and channel state information(CSI) to optimize network lifetime, using the weighting function to select the relay set. Simulation...
In order to optimize the performance of cooperative communication system, it presents a dynamic multi-relay amplify forwarding (AF) cooperation node selection algorithm, considering jointly the residual energy information of nodes and channel state information(CSI) to optimize network lifetime. Theoretical analysis and simulation results show that, for dynamic relay power distribution, performance...
