Data gathering is a basic function in wireless sensor networks (WSNs). With the energy constrained nature of the wireless sensor nodes, energy-efficient routing algorithms need to be carefully designed before wireless sensor networks are widely deployed for data gathering. This article proposed an energy-efficient cluster routing algorithm (ECRA) for data gathering in wireless sensor networks. Firstly,...
Since the nodes in wireless sensor networks operate on limited power, it is an important issue to design efficient data gathering scheme that can save energy while meeting the needs of application. In this paper, we propose an energy-efficient cluster-based data gathering protocol (ECDGP). ECDGP uses a new clustering algorithm based on belief degree for clusterhead election. Furthermore, ECDGP selects...
