Abstract

Based on the optimal power allocation in cooperative transmission

two distributed algorithms

distributed separate route and power allocation algorithm （D-SRPA） and distributed joint route and power allocation algorithm （D-JRPA）

were proposed. The two algorithms combining the PHY （physical layer） and MAC （media-access control） protocol can get the similar performance as the corresponding centralized algorithms. Simulation results show that com- pared with D-JRPA

D-SRPA can save the total transmission power more efficiently.
