Abstract: Mobile Adhoc Networks (MANETS) have no fixed infrastructure and are better than cellular mobile networks which have the fixed infrastructure. In MANETS nodes are mobile and hence can be implemented in military, RADAR, aircraft, air force and in hard real-time systems. Bandwidth is limited in the case of wireless networks, so the routing protocols should not occupy a large portion of the network capacity to keep the routing information. To provide optimized QoS in MANETS, Zone Routing Protocol (ZRP) can be used to increase the mobility, throughput, speed and decrease delay, routing overhead, cost and power consumption. It is a hybrid protocol, which uses the advantages of both pro-active and reactive protocols. The cache in the optimized ZRP considers the parameters the priority, the routing information, the lifetime and the latest access time. The tradeoffs between the various parameters are to be considered depending upon the applications.
