Performance analysis of MANET routing protocols for military applications

Abstract

Recent advancements in artificial intelligence have made human independent missions possible. These missions have to meet deadline constraints for successful implementation. So making up to a mission by multiple robots rather than a single robot is preferred. An effective communication link is required between these robots to accomplish the given mission. One such effective network which can be deployed in tactical or emergency scenarios is an ad-hoc network. Moreover, the performance of the network depends on the routing protocols used. Also, the performance of routing protocols depends on the way the nodes are moving in the given area where the network has to be setup. Thus simulation of ad-hoc routing protocols such as Ad-hoc On-Demand Distance Vector (AODV), Dynamic Source Routing (DSR), Destination Sequenced Distance Vector (DSDV), and Optimized Link State Routing (OLSR) has been done in NS-2.35 with Nomadic Community Mobility Model (NCMM) and Random Waypoint Mobility Model (RWPMM) obtained from BonnMotion tool. Network performance parameters considered are throughput, latency, and overhead. It is observed that routing protocols perform better in RWPMM than NCMM. With RWPMM, DSDV routing protocol provides high throughput as well as less latency and DSR routing protocol provides low overhead.
