Contemporary growths in the field of microelectronics and network communications which make it achievable to organize in a wide range of Wireless sensor network. These sensor networks have recently come into prominence because they have hold the potential to revolutionize many segments. As we know that wireless sensor network suffers from excessive packet loss, over hearing, retransmission of the packet due to node mobility and constant energy dissipation. Routing protocol techniques is one of the research area in wireless sensor network. So by crafting an efficient routing algorithm to improve the network lifetime. In this paper, we are drawing a new technique for cluster-head selection by analyzing the lasting energy of the node and also considering the type of communication between the nodes and cluster-head. This technique is compared with the conventional LEACH. The work is simulated in MATLAB, and the result will shows increasing in the network lifetime by increasing the number of alive node and decreasing the number of dead node.
