摘　　要：如何降低节点能耗,延长节点生存时间是移动Ad hoc网络的一个研究热点,对此提出了一种基于拓扑控制的节能算法ECA/TC(Energy Conservation Algorithm with Topology Control)。该算法在RNG图的基础上,采用邻节点消除机制,有效降低了节点的传输功率及广播消息在网络中的转发次数。仿真结果显示该算法具有较好性能,能够提高网络能效。How to optimize nodes energy consumption and lifetime is a hot issue in mobile Ad hoc network.An energy conservation algorithm based on topology control is proposed.By using neighbor elimination scheme as well as RNG topology control,the transmission power of each node and the redundant broadcast messages are reduced.Simulation resuhs show that the algorithm has better performance and can improve network power efficiency.
