Abstract: Wireless Ad hoc networks energy consumption is related to per-node transmission power,routing hops and end-to-end throughput.A novel energy consumption model is proposed to analyze the influence of topology control on energy consumption and the lifetime of networks.Simulation results show that topology control can extend the network lifetime and perform well in terms of energy consumption in lightly loaded networks,while in heavily loaded networks it can not effectively decrease energy consumption of networks,but can extend the network lifetime.

Key words: topology control, power control, network lifetime, energy consumption model

摘要: Ad hoc网络的能耗主要与节点的发射功率、数据包转发次数及端到端通过量三者有关。通过建立网络能耗模型分析和实验仿真发现,对负载较低的网络实施拓扑控制技术可以降低网络能耗、延长网络生存期;而对负载较高的网络实施拓扑控制技术,虽不能有效降低网络能耗,但仍然可以延长网络的生存期。
