Enhancing reliability on wireless sensor network by AODV-ER routing protocol

This paper proposes a reliable routing protocol on wireless sensor networks based on the well-known AODV routing protocol. The main idea of proposed protocol is to find the route which has the highest end-to-end reliability from the source to the destination based on the hop-by-hop packet reception probability. We consider the end-to-end reliability of a route as the product of hop-by-hop packet reception probability of the links in the route. For reliable delivery, our protocol chooses the route with the highest end-to-end reliability. We have evaluated the performance of the proposed protocol using Qualnet simulator. Our experiment shows that the proposed protocol is superior in terms of packet delivery ratio, the end-to-end delay and the delay jitter.
