Mobile Ad-Hoc Networks are rapidly deployable and self-configuring networks. In MANET all the network node work as a router and must be capable to relay traffic from one to another since communicating nodes might be out of range. MANET is characterized by dynamic topology, possibly unidirectional links, constrained resources and network partitions. The main two attributes are mobility and multi-hop. [1][3] The size of MANET can be varied from small static network to highly large dynamic network. MANET use dynamic changing network topologies that are proactive, reactive and hybrid protocol. [1][2] In this paper, an attempt has been made to compare performance of Proactive, reactive and hybrid protocol for the MANET. A comparative study of DSDV (proactive) DSR (reactive) and ZRP (hybrid) has been done on the basis of their performance in MANETs using NS2 simulator. Packet delivery fraction ratio and throughput are considered as a performance parameter for evaluating the performance of DSDV,DSR and ZRP protocol.
