Performance investigations of routing protocols in manets

Abstract

In MANETs each node acts both as a host and a router and therefore forwards packets for other nodes using different routing protocols. The primary objective of this paper is to compare the performance of different routing protocols for wireless ad hoc networks in a simulated environment against varying network parameters and traffic (UDP, different number of connections/streams) to provide a qualitative assessment of applicability of protocols in different scenarios. The performance differentials are analyzed using varying node mobility, network size, maximum speed, traffic load and data rate on NS-2.34[1]. We will also simulate and analyze the wireless ad-hoc network routing protocols considering TCP as transport protocol and FTP as traffic generator against different network parameters. © 2011 Springer-Verlag.
