A Wireless Sensor Network (WSN) is a wireless computing devices network consisting of spatially distributed autonomous devices using sensors to cooperatively monitor physical or environmental conditions, such as temperature, sound, motion, intrusion or pollutants, at different locations. The purpose of designing these networks is gathering information from the environment and sending them to the sink node. One of the most important issues in these kinds of networks is energy efficiency. The longer the communication distance, the more energy will be consumed during transmission. So, clustering is a way to reduce energy consumption. In this paper, the authors propose a dynamic clustering algorithm using genetic algorithm.
