摘要 在协作传输最优功率分配的基础上,提出了两种分布式协作路由和功率分配算法,分布式分离路由和功率分配算法与分布式联合路由和功率分配算法。这两种算法集合了物理层和媒质接入层协议,能够取得近似集中式算法的性能。仿真结果表明相对于联合协作路由和功率分配算法,分离协作路由和功率分配算法能够更加有效地节省总的发送功率。 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.
