Abstract
In mobile ad hoc networks (Manets), routing protocol plays the most important role. In the last decade, Ad hoc On-demand Distance Vector (AODV) routing protocol becomes the attention of focused research on Manets world wide. A lot of protocols had been proposed to improve and optimize AODV routing protocol to achieve the best in quest of reliable protocol. In this paper, we proposed a new variant of AODV routing protocol based on combination of two protocols, AODV+ and R-AODV. We called it AODV-UI. The proposed protocol has some advantages such as availability gateway mode and optimize route discovery which adopt reverse route. This paper presents a performance analysis of our proposed protocol. We measure some performance indicators such as end-to-end delay, packet delivery ratio and routing overhead. The simulation results show that our proposed protocol AODV-UI outperformed AODV+ especially in terms of routing overhead. It decreases the end-to-end delay by 19.24% and increases the packet delivery ratio by 7.54% as well as decreases the routing overhead by 68.09%.
Keywords: AODV, routing protocol, performance analysis
