An Improvement of AODV Protocol Based on Reliable Delivery in Mobile Ad hoc Networks

摘要：

AODV protocol is a comparatively mature ondemand routing protocol in mobile ad hoc networks. However, the traditional AODV protocol seems less than satisfactory in terms of delivery reliability. This paper presents an AODV with reliable delivery (AODV-RD), a link failure fore-warning mechanism, metric of alternate node in order to better select, and also repairing action after primary route breaks basis of AODV-BR. Performance comparison of AODV-RD with AODV-BR and traditional AODV using ns-2 simulations shows that AODV-RD significantly increases packet delivery ratio(PDR). AODV-RD has a much shorter end-to-end delay than AODV-BR. It both optimizes the network performance and guarantees the communication quality.
