MANET Performance Estimation Using Manhattan Distance Approach

Wireless communications is a demand of the current technological era. Various number of routing protocols are available in Mobile Ad-hoc Network (MANET) out of which table driven and on demand routing protocols are widely used. AODV is a on demand type of protocol specifically designed for mobile wireless nodes interconnection in an ad-hoc manner, to find routes as on requirement basis with minimal route acquisition potential and control overhead. In general it is working on Euclidean distance. In this paper we propose a new approach to replace Euclidean distance with Manhattan distance and destination IP is also incorporated into main AODV header to improve its performance and reduced amount of data loss. Network Simulator (NS-2) is used as a simulation tool, and wireless environment created by MAC 802.11 protocol. Proposed routing protocol performance evaluated in terms of PDR, E2E packet delay, dropped packet and dropped data bytes. It is also compared with the performance of normal AODV.
