Obstacle-Aware Fuzzy-Based Localization of Wireless Chargers in Wireless Sensor Networks

Abstract

This paper introduces an obstacle-aware fuzzy-based scheme for the localization of wireless chargers in wireless sensor networks (WSNs), which aims to deploy chargers in both fixed and/or multiple duty-cycled networks. A power harvesting model is proposed that considers the obstacle penetration loss in the harvested power from multiple chargers. We take advantage of the fuzzy control system (FCS) scheme to gain prior knowledge about the distribution pattern of the nodes. The simulation results confirm that deploying chargers based on this scheme decreases the required number of chargers, in comparison with the nonfuzzy algorithms by up to 59.6% in multiduty-cycled and 34.4% in fixed duty-cycled scenarios, in the best cases.
