Mobility-aware access-based clustering in mobile wireless ad hoc networks

Wireless mobile ad hoc networks consist of mobile nodes which can communicate with each other in a peer-to-peer fashion (over single hop or multiple hops) without any fixed infrastructure such as access point or base station.In a multi-hop ad hoc wireless network, which changes its topology dynamically, efficient resource allocation, energy management, routing and end-to-end throughput performance can be achieved through adaptive clustering of the mobile nodes.Most of the clustering approaches proposed in the literature primarily focus on the algorithmic aspects of clustering without considering the practical implementation issues and these are ofben reactive in nature.In this thesis, v/e propose a framework for Mobility-Aware Proactive Low Energy (MAPLE) clustering in ad hoc mobile wireless networks.The proposed approach addresses the problem of clustering in a mediumaccess control framework and enables proactive and energ-y-efficient clustering by exploiting the node mobility information.MAPLE is compared to non-access-based clustering and access-based clustering protocols.Simulation results show that the proposed framework results in superior clustering performance in terms of stability, load distribution a¡rd control message overhead compared to other clustering approaches proposed in the literature.
