Abstract

Mobile Ad Hoc Network is a self configured, the server through wireless links. In this, our ultimate goal of Infrastructure less networks, there will be vast usage among the mobile users. Each and every node in the network is free to move independently in any direction. Therefore, changes may happen on its links to other links frequently. Due to its dynamic topology, there will be insufficient in their bandwidth consumption and get affected by several delays. Some of the earlier caching schemes like Smart server-based update mechanism and server-based schemes are used to improve consistency of data. But, the problem of caching consistency is, difficult to provide broadcasting of desired data to all the entire nodes and to maintain an entry table list for each and every node. Hence, this paper describes various schemes used ad hoc networks is to provide mobile node, to access or retrieve the required information by overcoming disadvantages of mobile ad hoc networks. In ad hoc networks, mobile nodes communicate with each other using multihop wireless links because each and every node maintains an entry list of Timestamp (last modification time), Query ID, routed directory’s ID, and its neighboring node’s address .If a node gets disconnected for a long time, using this entry list it can reach that appropriate cluster head. After, the server checks that disconnected/rejoining node by sending Invalidation Reports (IRs), that consists of timestamp period, and also checks whether that node belongs to that particular Cluster to improve cache consistency by introducing new head and also checks the contents whether it is modified or methodologies and also pay way to reduce severe delays and various network latencies under mobile ad hoc networks. Finally, we analyzed the difference between pros and cons.
