无线传感器网络仿真平台能耗模型研究

Research on Energy Consumption Model of Simulation Platform for Wireless Sensor Networks

GloMoSim不具备能耗模型,无法对能耗进行仿真,将其应用于无线传感器网络仿真时存在较大局限性。为了使Glo-MoSim能够满足无线传感器网络能耗仿真的需要,根据GloMoSim的平台架构和仿真原理,结合无线传感器网络的工作特性,提出了基于节点状态能耗权值和持续时间的能耗模型,并扩展了GloMoSim的能耗仿真功能。利用扩展后的GloMoSim对AODV协议能耗进行了仿真实验,并与NS2的仿真结果进行了比较。实验结果表明,能耗模型能够正确的仿真协议的能耗,且相对NS2,能耗模型配置更加方便。因此,能耗模型具有良好的可靠性和易用性。

GIoMoSim does not have energy consumption model, can not simulate energy consumption, therefore, there is a big limitation when applied in the simulation of wireless sensor networks. In order to enable GloMoSim to satisfy the need of energy consumption simulation of wireless sensor networks, according to its architecture and simulation principle, combining the characteristics of wireless sensor networks, an energy consumption model based on energy consumption weight and duration was proposed, and the function of energy consumption simulation was expanded. Using the expanded platform, the simulation experiment of AODV protocol was carried out, and the result was compared with that of NS2. The experimental result indicated that the model can simulate energy consumption of pro- tocols correctly, and the configuration is more convenient compared with NS2. Therefore, the energy consumption model has a good reliability and usability.
