摘要
针对在移动Ad hoc网络中,由于节点移动和能量有限导致节点失效、传输链路不稳定的问题,改进原有链路剩余时间计算方法,并与节点剩余能量结合计算路径质量,将路径质量作为判决条件引入到AODV协议中,最终形成基于链路质量的路由算法。仿真表明改进的算法可提高选择路径的可靠性,降低丢包率和平均端到端时延。
Because of node mobility and energy limitation lead to node failure and transmission link instability in Ad hoc Net- works, improve original Link Lifetime calculation method, calculate path quality with node residual energy, the path quality as a judgment condition introduced into AODV protocol,Ultimately form routing algorithm based on link quality. Simulation results show that the improved algorithm can improve the selection path reliability and reduce the packet loss rate and the average end- to-end delay.
