Performance Evaluation of AOMDV Protocol Based on Various Scenario and Traffic Patterns

Abstract

A MANET is an interconnection of mobile devices by wireless links, which forms a dynamic topology. Routing protocols play a vital role in transmission of data across the network. The two major classifications of routing protocols are unipath and multipath. In this paper, we have evaluated the performance of a widely used on-demand multipath routing protocol called AOMDV. This protocol has been selected due to its edge over other protocols in various aspects, such as reducing delay, routing load etc. The evaluation of AOMDV protocol is carried out in terms of four scenario patterns such as RWM, RPGM, MGM, and GMM in two different traffic patterns such as CBR and TCP using NS2 and Bonn Motion.

Comparative Performance Analysis of AODV and AODV-MIMC Routing Protocols for Mobile Ad hoc Networks

“…Packet Delivery Ratio [14,15] is the ratio of data packets delivered to the destination to those generated by the sources and is calculated as follows:…”

“…Routing overhead [14,15] is the total number of control packets or routing packets generated by routing protocol during simulation and is obtained by…”

“…Normalized Routing Overhead [14,15] is the number of routing packets transmitted per data packet towards destination and calculated as follows:…”

“…Average End-to-End [14,15] delay is the average time of the data packet to be successfully transmitted across a MANET from source to destination. It includes all possible delays such as buffering during the route discovery latency, queuing at the interface queue, retransmission delay at the MAC, the propagation and the transfer time.…”

“…Packet Loss Ratio [14,15,16] is the ratio between the number of data packets sent and the number of data packets received. It is calculated as follows:…”
