Mobile Ad hoc NETwork (MANET) is a collection
of mobile nodes that are arbitrarily located so that the
interconnections between nodes are dynamically changing. In
MANET mobile nodes form a temporary network without the
use of any existing network infrastructure or centralized
administration. A routing protocol is used to find routes
between mobile nodes to facilitate communication within the
network. Route should be discovered and maintained with a
minimum of overhead and bandwidth consumption. A wide
range of routing protocols for MANETs has been proposed by
researchers to overcome the limitations of wired routing
protocols. This paper presents performance evaluation of three
different routing protocols, i.e., Dynamic Source Routing
(DSR), Optimized Link State Routing (OLSR) and Fisheye
State Routing (FSR) in variable pause time. We have used
Random Waypoint mobility model and performed simulations
by using QualNet version 5.0 Simulator from Scalable
Networks. Performance of DSR, OLSR and FSR is evaluated
based on Average end to end delay, Packet delivery ratio,
Throughput and Average Jitter.
