For saving energy and balancing the energy load among nodes, an energy-efficient data gathering algorithm (EDGA) based on clustering is proposed in this paper, which is used to gather data in wireless sensor networks. Firstly, the nodes compete for becoming a clusterhead according to residual energy and the distribution of neighbor nodes. Secondly, the clusterhead selects the active nodes according...
Data gathering is one of the most important operations in wireless sensor networks. Since the nodes operate on limited power, it is a critical task to design an energy-efficient data gathering algorithm. In this paper, we propose an energy-efficient data gathering algorithm (EDGA) in which the network is grouped into clusters (each with a clusterhead) and the nodes form chains in each cluster. Firstly,...
