Network lifetime aware anchor selection for energy harvesting wireless sensor networks

Abstract

Advances in renewable energy harvesting technologies have initiated great possibilities in wireless sensor networks with energy harvesting nodes. Network lifetime now depends not only on the residual energy of the nodes but also on their energy harvesting rates. Mobility of data sink has added a new dimension to data collection techniques as well. This paper focuses on lifetime maximization of EHWSNs using an anchor selection algorithm which is regulated by an energy harvesting-aware weighted average function. The algorithm yields a set of EH-sensor nodes as anchors and a mobile data collector collects data from these anchors. The results of experiments show that our anchor selection algorithm out performs traditional lifetime maximization algorithms.
