This paper aims to compare performance of some routing protocols for Mobile Ad Hoc networks (MANETs). A Mobile Ad Hoc Network (MANET) is a collection of wireless mobile nodes forming a temporary network without using any centralized access point, infrastructure, or centralized administration. Data transmission between two nodes in MANET's , requires multiple hops as nodes transmission range is limited. Mobility of the different nodes makes the situation even more complicated. Multiple routing protocols especially for these conditions have been developed during the last years, to find optimized routes from a source to some destination. This paper presents performance evaluation of three different routing Protocols (AODV, DSR and ZRP) in variable pause times . We have used QualNet Simulator from Scalable Networks to perform the simulations. Performance evaluation of AODV, DSR and ZRP is evaluated based on Average end to end delay, TTL based hop count and Packet delivery ratio.
