Improving data accessibility in mobile ad hoc networks

Abstract

In mobile ad hoc networks, the networks topology changes dynamically and partition among mobile nodes occur frequently. These are due to unpredictable mobility of mobile nodes and each mobile nodes act as routers which discover and maintain routes, and forward packets to other nodes. We address the problem of replication in mobile ad hoc networks by exploring group mobility approach. Group mobility refer to the scenario where several mobile nodes are tends to move together. Group mobility approach is used to increase the data accessibility among mobile nodes through data replication and consistency group management. It also guarantees basic level of system performance, such as throughput, delay and reduces the networks traffic among mobile nodes.
