Certain improvements in cooperative caching for manet using evolutionary algorithm

Abstract

Interest in Mobile Ad Hoc Networks has increased rapidly due to the immense growth in wireless communication technologies The aim of the research work is to improve data availability and gaining efficiency by pooling resources of mobile nodes using local and global update mechanisms newlineIn this research work a Cluster Based Cooperative Caching Technique CBCCT based on mobility prediction is proposed to handle mobile disconnections The network is divided into clusters and the cluster head is selected based on the power level and connectivity The details of the cached data items in the cluster and its adjacent clusters are maintained in the local cache table and the global cache table respectively Experiments are conducted using Network Simulator 2 by varying the number of nodes and mobility speed The proposed CBCCT increases packet delivery ratio decreases data access delay and control overhead than the existing Global Cluster Caching GCC technique since it avoids the frequent cache updates newlineThe cluster mobile nodes accessed the desired data from the remote source and cached in its local cache newline newline
