Abstract: ZRP (Zone Routing Protocol) is a hybrid routing Protocol specifying routs within a region of a network, called routing zone. ZRP can be configured for a particular network by adjusting the routing zone radius. Routing zone radius (R) is defined based on the number of hops. So, a routing zone maintains some nodes that their distances to a specified node are at most R hops. In fact, ZRP is designed for optimizing the (Query/reply) mechanism efficiency. ZRP is a combination of proactive and reactive protocols; within the zone, it is in proactive and between zones is reactive. The first one is called IARP and the latter one IERP. In this paper, we intend to evaluate the ZRP Performance in a network. To do this, we change the zone radius and performance is evaluated by measuring the control traffic generated during routing process. In fact, control traffic is viewed as the sum of the IARP routing update packets and the transmission of IERP request/reply/failure packets. Our results determine the optimum zone radius considering the node velocity, the number of transmitting nodes and the total number of nodes.
