Routing is an important part of wireless ad hoc network conventionally there are two approaches first one is proactive and another one is reactive. Both these approaches have some disadvantages and to overcome the problems hybrid routing protocols designed. ZRP (Zone Routing Protocol) is one of the hybrid routing protocols, it takes advantage of proactive approach by providing reliability within the scalable zone, and for beyond the scalable zone it looks for the reactive approach. It (ZRP) uses the proactive and the reactive routing according to the need of the application at that particular instance of time depending upon the prevailing scenario.
