Performance Analysis of DYMO, LANMAR, STAR Routing Protocols for Grid Placement model with varying Network Size

A Mobile Ad hoc networks (MANETs) are self organized wireless networks which are able to connect on a wireless medium without the use of a infrastructure or any centralized administration. Due to the absence of infrastructure, nodes may move frequently and the topology may change dynamically. The mobile nodes perform both as a host and a router forwarding packets to other nodes. Routing in these networks is highly complex. Due to moving nodes, many routing protocols have been developed. Performance of each protocol is depending on their working in different conditions. In this paper a detailed simulation based performance analysis is performed on the mobile ad hoc routing protocols-Dynamic MANET ondemand (DYMO), Landmark Ad hoc routing (LANMAR), Source Tree Adaptive routing (STAR) in Grid placement model with varying network size using QualNet 5.0.1 simulator
