Abstract: AODV algorithm chooses the path between the source node and destination node according to the least hops of path, which ignores the possibility of the existence of low-quality links. The improved routing protocol L-AODV collects the link quality information during the broadcasting progress in network. According to the link quality information included in arrived RREQ packets, the destination nodes will choose the path after evaluating the performance by computing path cost. Experimental results show that L-AODV routing protocol is improved in packet delivery rate.

Key words: wireless sensor network (WSN), L-AODV, LQI, RREQ, RREP
