Wireless sensor networks have become one of the most tempting networking technologies since it can be deployed without the need of a communication infrastructure. In general, there are some major concerns with this technology. That is, sensor node should have a long lasting system lifetime. And the system should keep the livability of nodes in a received level during the using process. In such systems node's energy, which is the main factor, is used to select cluster-heads. In this paper, we gave a new method called LEACH-improve, discussed the relation between the energy, the cluster and coverage together. And we compared the simulation result with the LEACH and HYENAS methods. This mode could serve a better solution scheme for solving cluster-heads selection problem in sensor network.
