J-Sim下WSNs仿真框架的扩展设计与实现

Design and Implementation of J-Sim Framework Extension to WSNs Emulation

随着无线传感器网络(WSNs)的应用,如何延长网络生命周期,对路由协议的研究提出了挑战。为了更好地研究能量高效利用的WSNs路由协议,建立对WSNs能耗支持较好的仿真平台具有十分重要的现实意义。针对J-Sim下WSNs框架对能耗仿真支持不好的问题,在现有的WSNs框架基础上提出了一种支持能耗仿真的WSNs仿真框架并在该框架上扩展实现LEACH协议。实验结果表明改进后的WSNs框架可以真实地仿真WSNs,获取有价值的仿真结果。

With the application of wireless sensor networks （WSNs）, how to prolong the lifetime of network is a challenge to the research of muting protocol. In order to make research on the energy- efficient muting protocol of WSNs, building up an emulation platform that can support energy consumption simulation of WSNs has significant realistic significance. With regard to the problem that energy consumption simulation was not supported well by the sensor network framework in J - Sim, a WSNs emulation framework that can support energy consumption was proposed. And then LEACH was implemented on the framework. The experiment result shows that the improved sensor network framework can actually simulate wireless sensor networks and obtain valuable simulation results.
