Distributed fuzzy logic based routing protocol for wireless sensor networks

A Wireless Sensor Network is a special network that requires adaptive methods and techniques to meet the application requirements. Optimizing the energy consumption and enhancing the network lifetime while routing data from sensor nodes to the base station is the subject of extensive research works. This paper presents and evaluates an energy efficient cluster-based routing protocol that uses a fuzzy logic module during the cluster-head election process in order to increase the network lifetime. The objective of this work is not to minimize the whole network consumption, but to balance the consumption over nodes to increase the network lifetime. The proposed protocol is based on the well-known cluster-based routing protocol, the Low Energy Adaptive Clustering Hierarchy protocol. The performance of the proposed fuzzy-logic-based algorithm is evaluated using MATLAB simulation.
