چکیده:

Being an important factor in designing Wireless Sensor Networks, network lifetime depends on the energy of the sensor nodes which is limited by the battery of the node.Clustering is considered to be an energy management strategy in wireless sensor networks, and Leach is one of the most wellknownclustering mechanisms. Random cluster selection in this method has lead to its inefficiency. In this paper we proposed two algorithms, GP-Leach and HS-Leach. We improved the energy consumption by partitioning the network and using the evolutionary algorithms for optimized cluster head selectionconsidering WSN nodes’ position information and residual energy. The simulation results performed in MATLAB shows that our proposed algorithms are more efficient and theyincreased the lifetime of the network
