Analysis of Cluster Based Zone Routing Protocol in MANET through Network Simulator

The employment of routing data from a source to a destination in a network is dispute. Many routing protocols are suggested for mobile ad-hoc networks. Usually there are two approaches first one is Proactive and another one is Reactive [3]. In which the Zone Routing Protocol (ZRP) is a composite routing protocol for MANET [2], the ZRP integrates the advantages of the proactive and reactive approaches by conserving an up-to-date topological map of a zone medial on each node. Within the zone, routes are instantaneously available. For destinations outside the zone, ZRP manipulates a route ascertainment procedure, which can profit from the local routing information of the zones. Clustering is a method that divides the network into inter depended substructures, called clusters. Each cluster has a cluster head. It acts as a temporary base station within its zone or cluster and communicates with other cluster heads. In existing system [4], [5], Source cluster node transmits a packet to the source cluster head and then it transmits a packet to destination cluster head through intermediate node and intermediate cluster head. The destination cluster head moves a packet to the destination node. In proposed system the source cluster node transmits a packet to the source cluster head then it transmits a packet to the destination cluster head and it moves to the destination node without using intermediate nodes and cluster heads. The proposed System is simulated in Network Simulator 2 (NS2). The ZRP supplies good packet delivery ratio and curtails time delay compared to existing system. Without using intermediate nodes curtails the time to bring back the route to destination and it utilizes few nodes therefore the packet loss is less. Each cluster heads knows about neighbors cluster head therefore it is easy to identify the destination cluster head and route discovery to the destination is understandable one.
