基于移动性的功率感知路由协议

Mobility-based Power-aware Routing Protocol in the Adhoc Networks

移动Ad-hoc网络中节点一般由电池提供能量,有效地节约能量显得尤为重要。在功率感知和AODV协议的基础上,提出了一种基于移动性的功率感知路由协议(M-PAR)。协议引入了可用邻居节点平均能量值和节点相对移动性值,选择可用邻居节点平均能量值高,且相对移动性值小的链路作为路由。仿真验证表明:与传统的PAR协议相比,M-PAR协议获得了较好的节能效果,网络生命周期提高了50%。同时,在包投送率、端到端延时取得了较好的改善。

Mobile Ad-hoc network is a collection of nodes equipped with low power device for data transmission.Efficient energy conservation plays an important role in the performance of wireless Ad hoc networks.A mobility-based power-aware routing protocol( M-PAR) based on the Power Aware Routing and AODV is proposed.It introduces the average energy of available neighbor nodes and relative mobility values,select an link as routing which has maximum average energy of available neighbor node with minimum relatively mobility values.Simulation results show that:compared with the traditional PAR,M-PAR obtains a good energy saving effect,the network lifetime improved by 50%.Meanwhile,the package delivery rate,end to end delay achieves good improvement.
