摘要
提出了一种移动 Ad Hoc 网络中以优化整体能量消耗为目标的多径速率分配算法,该算法分布地运行在各路由源节点,综合考虑路径间速率调整对路由内部和外部的功率影响,使用功率增量的方式对各路径的速率进行动态转移。仿真结果表明,在保证总传输速率以及服务质量(误码率)的前提下,该算法能使移动 Ad Hoc 网络路由的总能量消耗得到优化。
In this paper we propose a dynamic allocation algorithm to achieve minimum power consumption in mobile Ad Hoc networks. Being distributed on each source node, the algorithm considers the influence of rate change on the power consumption in inter-routers and intra-routers, and uses varying granularity increment in the rate transferring among paths of the route. Simulation results demonstrate that the proposed approach can reach the minimum power consumption in the whole mobile Ad Hoe network, while guaranteeing the constant QoS in terms of the transmission rate and the Bit Error Rate （BER）.
