A Survey on Zone Routing Protocol Techniques

In Mobile Ad-hoc Networks (MANET), the nodes intercommunicate through single-hop and multihop paths in a peer-to-peer fashion. Intermediate nodes between two pairs of communication nodes act as routers. For constructing the mobile ad-hoc network the routing algorithm play an important role. The performance evaluations of the routing protocol for MANET are evaluated via simulation. Routing protocols for mobile adhoc networks have to face the challenge of frequently changing topology, low transmission power and asymmetric links.. The Zone Routing Protocol (ZRP) is a combination of the proactive and reactive routing protocol and maintaining an up-to-date geography map on each node of a zone centred. The routes are instantly available within the zone. The destination node which are outside the zone in the zone routing protocol, this protocol employs a route discovery procedure that can benefit from the local routing information of the zones.
