Hybrid energy efficient clustering based on residual energy, node degree and distance to base station (HEEC-RND) in heterogeneous WSNs

Abstract

Wireless Sensor Networks offer several applications but limit in their energy resource. Efficiency and lifetime of these networks depend on the proper use of their energy. Energy in these networks can be efficiently consumed using mechanism of clustering. Any clustering mechanism depends upon the criteria used in the cluster head selection. In order to select a Cluster Head, this paper presents a mechanism HEEC-RND that takes into account three factors — the node's residual energy, node degree and node's distance from the base station. Compared with other techniques, the technique increases the network lifetime and decreases the network energy decay.
