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 networks have been widely used in emergency, military and civil fields. However, Ad hoc network energy problems directly affect the life cycle and node lifetime of Ad hoc networks, and become the main problems to be solved in the development of Ad hoc networks. This paper addresses this issue by optimizing the DSR protocol with better performance in the network routing protocol and proposes an energy-saving mechanism based on energy control to improve the Hello mechanism for routing discovery. This paper presents the Maximum Minimum Power-Energy Weight (MMPEW-DSR) protocol for locally adaptive DSR routing protocols. The optimized protocol reduces the battery energy consumption and prolongs the lifetime of the network.
