Abstract
wireless sensor network are new type of wireless networks that have emerged for both civil and military applications. this thesis mainly focus on static sensor networks. in these networks, every node is capable of sensing, data processing, and communication. sensor nodes operate on a limited amount of battery energy consumed mostly at the transmission and reception at its radio transceiver. a merged algorithm between evolutionary algorithm (EA) and k-means clustering has been proposed. k-means divide the sensor network into k-clusters (K-Known) ;EA finds the optimal fitness of the network. this algorithm determines the optimal number of clusters cluster elements, and the head of each cluster. thus, the total distance will be reduced and this will lead to energy saving and long life time network.
