Performance Analysis of Hybrid routing protocol

Routing protocols for vehicular ad-hoc networks must deal with topology changes on a regular basis, low transmission power, and asymmetric connections. Under these conditions, proactive and reactive routing protocols work ineffectively. By keeping an updated map of a zone with each node centred, the Zone Routing Protocol (ZRP) merges merits of proactive and reactive methods. Routes within the zone immediately accessible. For packet destination exterior to zone radius, ZRP uses route locating process that takes merits of zones' routing direction. Zone Routing Protocol is described in this document. First, we'll go over the issue of routing in ad-hoc. Topology of ZRP, made up of sub-protocols, is described. We also go through query control mechanisms that are used to reduce amount of traffic generated during route discovery process. Actual execution of the protocol components is not specified by ZRP. As a result, we present the implementation guidance. Finally, we draw some conclusions for protocol's efficacy.
