Energy Efficient Wireless Sensor Networks Using Fuzzy Logic
Abstract
During the period 8/1/2003-11/30/2003, we have made lots of progress on energy efficiency of wireless sensor networks. We investigated the optimal number of clusters for a given number of sensors. Based on this theoretical result, we proposed a Fuzzy Energy Aware Topology Updated with REconfiguration for sensor-networks (FEATURES) scheme. This scheme provides a methodology on how to partition a sensor network to the desired number of clusters using fuzzy c-means, how to elect a clusterhead using fuzzy logic system via combining different descriptors of a sensor: distance of a node to the cluster centroid, its remaining battery capacity, and its degree of mobility. We also proposed an Access-Based Low Energy Hierarchy (ABLEH) to clustering protocols more adaptive to the dynamic nature of sensor networks. Besides, we studied energy efficient protocol design for large-scale wireless sensor network. Four papers were produced during these six months, and are attached to this report.
