摘要: Ad hoc网络有着广泛的应用前景。选择高速稳定的路径进行通信十分重要。在常用位置辅助(LAR)路由算法的基础上,提出了一种新的路由算法(NSLAR)。该算法引入节点稳定度这一参数,并以此作为路径选择的依据,从而增强了所选择路径的稳定性,减少了因为路径失效带来的重新路由次数。仿真结果表明,与LAR和QR算法相比,NSLAR算法具有更好的性能。

Abstract: Ad hoc networks have a bright future of enormous applications.The stability of selected paths is essential to the whole networks.Based on the typical Location-Aided Routing(LAR) algorithm,an improved routing algorithm(NSLAR)is proposed by introducing the node stability factor.This factor is used as the criteria to select routes,so that the stability of selected paths is enhanced and the rerouting times caused by the invalidation of selected paths are reduced.The results show that the NSLAR algorithm has better performance than LAR and QR algorithms.

Key words: Ad hoc networks, routing protocol, node stability, location-aided
