Performance of AODV Routing Protocol with Increasing the MANET Nodes and Its Effects on QoS of Mobile Ad Hoc Networks

Abstract

A mobile ad hoc network (MANET) consists of mobile wireless nodes. The communication between these mobile nodes is carried out without any centralized control. The ease of deployment and the infrastructure less nature of Mobile Ad hoc Networks (MANETs) make them highly desirable for the present day multi media communications. Traditional routing protocols may not suffice for real time communications it depends upon the conditions and our requirements. Though there has been considerable research in this area. In this paper, we are analyzing the performance of reactive routing protocol via increasing number of nodes and observing its effect on Quality of Service (QoS) of Mobile Adhoc Network. As we know routing protocols make an important role for improving QoS in Mobile Adhoc Network. The QoS depends upon several parameters like end-end delay, throughput, date drop and network load. The reactive routing protocol which we are considering is AODV for this scenario with MCHG [1] [2]. Here we are observing performance of Routing Protocol via enhancing the network size on the basis of following parameters: delay, throughput, traffic sent, traffic received, data dropped and network load. Network simulation tool used in simulation is OPNET Modeler (Ver. 14.0). Finally, this paper conducts simulation experiments in the conditions where we can improve QoS of MANET Network performance.
