Comparative analysis of routing protocols for wireless area networks and evaluation of the effectiveness

Abstract

A Mobile Ad Hoc Network (MANET) is a gathering of mobile nodes that want to communicate without any preplanned infrastructure and fixed organization of available links. Each node in MANET operates as a router, forwarding information packets for other mobile nodes. There are many routing protocols that possess different performance levels in different scenarios. The main task is to evaluate the existing routing protocols and finding by comparing them the best one. In this article been compared AODV, DSR and DSDV routing protocols in mobile ad hoc networks (MANETs) to specify the best operational conditions for each MANETs protocol. I study these three MANETs routing protocols by different simulations in NS-2 simulator. We describe that pause time parameter affect their performance. This performance analysis is measured in terms of Packet Delivery Ratio, Average End-to-End Delay, Normalized Routing Load and Average Throughput.
