关于无线传感器网络节能问题的研究——基于定向扩散路由协议的改进的探讨

The Advanced Research on Energy Conservation for Wireless Sensor Network

定向扩散路由协议作为无线传感器网络的一种重要的典型网络协议,是高能源有效性协议的代表。然而它有着明显缺点,那便是在初始和更新查询阶段存在着极大的开销。文章直接针对这个问题,以节能为目的,提出引入选择节点转发的方法来改进定向扩散路由协议。最后通过模拟实验得出的结果显示改进后的定向扩散路由协议能节省能量17.8%。改进后的定向扩散路起到了很好的节能效果。

As a representative of power-efficient protocols in wireless sensor network,Directed Diffusion has an important position among typical network protocols.However,there is an apparent difficiency with Directed Diffusion Routing Protocol：at the stage of initial inquiry and renewal inquiry,the network has a lot of energy cost.For a purpose of saving energy,the paper puts forward to use the method of forwarding nodes selection scheme to improve Directed Diffusion Routing Protocol.Through a simulation test,the result shows that the improved protocol can save energy by 17.8%.The conclusion is that the improved Directed Diffusion Routing Protocol has an outstanding progress on energy conservation.
