Abstract: 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 delay, improve network lifetime and transmission reliability.
