Research on DSR-Based Energy Routing Protocols for Ad Hoc Networks

移动Ad Hoc网络依靠有限寿命的电池供电,因此有效的节能策略在Ad Hoc网络的研究中显得极为重要,而DSR路由协议由于其在无线网络中的优越性,成为节能路由协议研究的热点。介绍了DSR路由协议以及Ad Hoc网络中节能路由协议的技术,然后围绕节点剩余能量和节点生存时间这两个节能参数,从节能效果、网络生存时间、协议复杂度、延迟等方面对基于DSR的各种节能路由协议进行了详细的对比分析,从而总结出基于DSR的节能路由协议的优缺点,最后指出了Ad Hoc网络节能路由协议研究的发展方向。

Efficient energy conservation strategy plays an important role in the research on mobile Ad Hoc networks, because mobile hosts in such networks usually work relying on limited - battery. The dynamic source routing （DSR） has many advantages in the wireless networks, so it beccmes the hot research subject of energy conservation routing protocols. Briefly introduces DSR and the concepts of energy conservation routing in Ad Hoc networks. And then uses two parameters of energy- saving which include the node＇s remaining energy and node＇ s survival time to make detailed analysis and compare among some energy conservation routing protocols based on DSR in the aspects of energy- saving effects, the network survival time, the protocol complexity, delay and other aspects. Then the advantages and weaknesses of energy conservation routing protocols based on DSR are concluded. Finally, the development orientations of Ad Hoc energy conservation routing studies are pointed out.
