摘要
Ad hoc网络在紧急事件、军事以及民用领域都得到了广泛的应用,但Ad hoc网络能量问题直接影响了Ad hoc网络的生命周期与节点生存时间,成为制约Ad hoc网络发展要解决的主要问题。该文针对这一问题,对网络路由协议中性能较好的DSR协议进行优化,提出基于能量控制的节能机制,对于路由发现Hello机制进行改进。给出局部自适应DSR路由协议的改进协议MMPEW-DSR(Maximum Minimum Power-Energy Weight),优化后的协议减少了电池能量消耗,延长了网络的生存时间。
Ad hoc network in an emergency,military and civilian areas have been widely used,but Ad hoc network energy problems which directly affect the life cycle of Ad hoc network and node lifetime,as a constraint to the development of Ad hoc network of the main problems to be solved。In this paper solve this problem,network routing protocols for better performance of DSR protocol optimization,proposed energy-saving mechanisms based on energy control,RREQ and RREP to improve.Improvements to of DSR are MMPEW-DSR(Maximum Minimum Power-Energy Weight),and optimized protocol reduces battery power consumption and extending the network lifetime.
