Ad Hoc网络中基于中继组的节能型路由方法

An Energy-efficient Relay Group-based Routing Scheme in Ad Hoc Networks

AdHoc网络的信息传输能耗主要与信息中继次数和每中继的距离有关,网络的维护能耗则关键取决于网络节点的状态。该文提出了一种基于中继组的路由建立方法(RGRP),它不仅能建立一条具有最佳中继次数信息传输能耗较低的路由,而且采用的分组方法能降低网络的维护能耗。仿真结果表明,RGRP的能耗特性和稳定性都有显著的提高。

This paper proposes an energy conservation routing scheme. At first, the energy consumption rate of a specific route depends on thenumber of hops as well as the length of each hop. On the other hand, the nodes in the networks are classed into group, and only one node is active ina group, thus the energy consumption in the network maintenance is reduced. A route with lower energy consumption pattern based on relay group isestablished, thus the stability of the route is advanced, and the energy consumption of information transmitting along the route is minimized.
