JIT_V6_N1_RP2 Gurpreet Singh Hardeep Singh Journal on Information Technology 2277-5250 6 1 8 13 MANET, AODV, OLSR, ZRP, NetSim Mobile Ad Hoc Network (MANET) is a wireless, infrastructureless network where each node acts as a router, transmitter, and data sink. The objective of this paper is to evaluate the performance of reactive, proactive, and hybrid routing protocols of Mobile Ad-Hoc networks (MANET's) for Custom application. The authors’ have evaluated three routing protocols, i.e. AODV, OLSR, and ZRP by using NETSIM simulator tool. The performance of these routing protocols is examined by two application metrics: throughput and delay. The study of protocols will be carried out and finally the results will be presented as to which routing protocol is a better one for MANET.
