Maximizing clusters lifetime in Mobile Wireless Sensor Networks
Tarek Moulahi, Salem Nasri, Hervé Guyennet · 2014
Clustering is an organizational approach which has been applied over flat Wireless Sensor Networks (WSNs) to induce a hierarchical structure. In clustered WSNs the communication overheads and the energy consuming are minimized. In addition, network tasks like routing, data aggregation as well as networks self-reconfiguration are more easy. Although many previous efforts, clustering in mobile WSNs (MWSNs) is always a challenging problem due to the dynamic topology of the network and the limit of sensor resources. In this paper, we propose a new scheme to maximize clusters lifetime in MWSNs which is based on link lifetime between mobile sensors. Performances of the proposed method are measured through a simulation study using NS-2.
