在易错无线传感器网络（WSN）环境下,提出一种鲁棒感知的路由算法。考虑影响网络鲁棒性的链接错误率、碰撞记录等因素,通过计算最小延迟代价函数实现路由决策。在路由选择时,采用避免潜在干扰和碰撞的方法,减少因退避和重传引起的延迟。仿真结果表明,该算法能减少传输延迟,延长网络生存时间及提高传输可靠性。

This paper presents a robustness aware routing algorithm in error-prone Wireless Sensor Network（WSN）.Considering factors of link error rate and collision record which affect the network robustness,it realizes routing decisions through calculating a minimum delay cost function.In routing selection stage,it uses a method of avoiding potential interference and collision to reduce delay caused by retransmission and backoff.Experimental results show the algorithm can reduce the transmission de...
