Performance Investigation of Routing Protocol with the velocity of 30 m/s for Random Mobility Model

Abstract

A mobile ad-hoc network (MANET) is a network of mobile nodes short of Infrastructure, linked by wireless links. While mobility is the key feature of MANETs, the frequent movement of nodes may lead to link failure. A mobile multi-hop wireless ad hoc network carries a dynamic structure feature, and each node has mobility; due to this, the network having altering topology change dynamically. Developing the wireless ad hoc network protocol is the major challenge because, compared to the wired routing node, all node is mobile, energy limitation, the node's physical location, and multicast routing. In this article, a comparative investigation of routing protocol performance for large wireless ad hoc networks (100 nodes) under the impact of the random mobile environment with the velocity of 30 m/sec for 1800 seconds with ten different results for each node-set. The comparative analysis includes packet delivery ratio, throughput, packet dropping ratio, routing overhead, and end-to-end delay quality of service (QoS) metrics. When the number of nodes and connections increases in the AODV and DSR protocol, throughput increases from 60.2835 to 514.3095 bits/sec and 58.953 to 443.991 bits/sec, respectively AODV routing protocol gives a more stable performance than the other routing protocol. ZRP and DSDV protocols also have excellent performance for the small network of 40 to 45 nodes. However, when the number of nodes increases from the 65 nodes, protocol performance drastically decreases, whereas the AODV gives a more stable performance.
