摘要：In the near future, computing environment can be expected based on the recent progresses and advances in computing and communication technologies. Next generation of mobile communications will include both prestigious infrastructure wireless networks and novel infrastructure less mobile ad hoc networks (MANETs). A MANET is a collection of wireless nodes that can dynamically form a network to exchange information without using any preexisting fixed network infrastructure. The special features of MANET bring these technology great opportunities together with severe challenges. This thesis describes the fundamentals of ad hoc networking by giving its concept, features, and applications of MANET. Some of the technical challenges MANET poses are also presented. The routing protocols meant for wired networks cannot be used for mobile ad hoc networks because of the mobility of nodes. The ad hoc routing protocols can be divided into two classes: – table-driven and on-demand. Routing in wireless mobile ad-hoc networks should be time efficient and resource Saving. One approach to reduce traffic during the routing process is, to divide the network into clusters. This work mainly focuses on clusterbased routing protocol CBRP) and its comparative analysis with three other on demand routing protocols. We present a scheme, called global cluster cooperation (GCC) for caching in mobile ad hoc networks where network topology is partitioned into nonoverlapping clusters based on the physical network proximity. In this scheme cluster cache state (CCS), which is the information regarding the contents of all the mobile nodes (MNs) within a cluster, is maintained at each node. In case of cluster cache miss, we propose to keep global cache state (GCS) at a node called cluster state node (CSN) and we also implement new protocol is Adaptive cache schema and compare to the another three protocols on the basis on Time complexity, Number of messages and size of the messages and give the simulated results.
