Performance Improvement of Cache Management In Cluster Based MANET

Abstract

Caching is one of the most effective techniques used to improve the data access performance in wireless networks . Accessing data fro m a remote server imposes high latency and power consumption through forwarding nodes that guide the requests to the server and send data back to the clients. In addition, accessing data may be unreliable or even impossible due to erroneous wireless lin ks and frequently disconnections. Due to the nature of MANET and its high frequent topology changes, and also small cache size and constrained power supply in mobile nodes, the management of the cache would be a challenge. To maintain the MANET's stability and scalability, clustering is considered as an effective approach. In this paper an efficient cache management method is proposed for the Cluster Based Mobile Ad- hoc NET work (C-B-MA NET) . The perfo rmance of the method is evaluated in terms of packet delivery ratio, latency and overhead metrics.
