Improving performance of AODV using ant agents

Abstract

MANETs is a wireless infrastructure-less network, where nodes or station are not fixed and nodes are communicated without any centralized structure. Due to large mobility of nodes, limited bandwidth, dynamic network topology and limited resources in MANET routing become inefficient and nfeasible. So, routing protocols have been developed or communication between the nodes can be done in an efficient and effective manner. The proposed work implements the feature of both Ad hoc on demand routing protocols and ant based routing strategy. The proposed protocol has been then simulated using NS2 and results have been compared against different-different performance parameters. The proposed protocol has been named as (ANT-AODV USING AGENTS) in order to improve the performance of AODV. This algorithm make use of ant-like mobile agents have been generated, and these agents are implemented on Ad-hoc on demand distance vector routing protocol (AODV). ANT-AODV USING AGENTS protocol is simulated under mesh topology, as this topology can withstand high traffic and provide multiple alternative paths in case of node failure in network. From the available multiple paths, the best alternative routes can be found in minimum time by applying Ant-Agents. Hence ANT-AODV USING AGENTS as compared to AODV do not use the route-discovery procedure again when there is failure of route. The comparison is presented in the form of graphs between ANT-AODV USING AGENTS and AODV by different-different number of nodes using different performance measures. Thus projected work evaluated and analysis the performance of ANT-AODV USING AGENTS and an work has been made to attain reduced end to end delay, less routing overhead, increased throughput and more packet delivery fraction during its simulation. Finally, it is concluded that ANTAODV USING AGENTS performs better than AODV protocol.
