Abstract :
We study the power allocation algorithms in the case of multi-source multi-relay (MSMR) amplify-and-forward wireless cooperative network in this paper. In this MRMS system, we consider that multiple users would communicate with one destination node with the help of multiple relay nodes in the same time. To guarantee the quality-of-service (QoS) for all the users and reduce the power consumption, we present min-total relay power allocation algorithm for relay nodes. Simulation results demonstrate the efficiency and fairness of our proposed strategy.
