Abstract
Enhancing the quality of service is still facing various challenges due to nature and configuration of mobile ad-hoc network (MANET) such as free movement of nodes, unpredictable changes in network topology as no infrastructure exist in the network. The large usage of mobile ad-hoc network in various applications raises the demand to enhance the performance as well as reduce loss of packets through various factors. The routing protocols play the most important aspect in MANET. There are three kinds of routing protocols that are: reactive, proactive and hybrid that are utilized to optimize the network’s functionality. Ad-hoc on-demand Distance victor (AODV) routing protocol is the popular used to achieve best output result. The most important objectives of this paper are to enhance the performance of mobile ad-hoc network by using AODV protocol. This paper gives some changes in AODV routing protocols that’s assist the performance enhancement of AODV in mobile ad-hoc network. The simulation is carried out on the network simulator NS2 and the output result show the improved AODV has excellent performance in term of packet delivery ratio, secondly throughput, third is the routing overhead and finally is end to end delay.
