无线网卡能耗建模及在GloMoSim中的实现

Modeling for Energy Consumption of Wireless Network Interface Card and Its Realization in GloMoSim

参照笔记本电脑无线网卡各工作模式下功率消耗实测结果,建立了ad hoc网络结点无线网卡能耗模型,并介绍了如何在GloMoSim仿真环境中进行实现。此模型可广泛用于ad hoc网络无线结点能量消耗的研究中。运用新模型对IEEE 802.11节能模式的仿真表明:在流数目较多网络负荷较大时802.11节能模式并不能有效节省结点能耗,协议还需进一步改进。

Based on actual measurement results of the power consumed by laptop wireless network interface card under various working modes, an energy consumption model is proposed. How to realize it in GloMoSim is also introduced. This model can be widely used in researches on node energy consumption in ad hoc networks. With the new model, simulation results on IEEE 802.11 protocol with power saving mode show that when there are many flows in the network and the traffic load is rather heavy, this protocol cannot save energy and needs further improvements.
