In this paper, an algorithm based on cluster head selection according to distance is proposed for improving the sensor network life time. This protocol obtains a good concert in terms of period by matching the energy capacity between all the nodes. This clustering procedure help to delay the life of wireless sensor network, especially in unfriendly environment where battery replacement of single sensor nodes is not conceivable after their distribution in the given target area. Therefore, the anticipated technique to allocate the role of the Cluster Head (CH) among the wireless sensor nodes in the same cluster is dynamic to increase the lifetime of the network.
