A wireless sensor network consist of small devices, called sensor nodes that are equipped with sensors to monitor the physical and environmental conditions such as pressure, temperature, humidity, motion, speed etc. The nodes in the wireless sensor network were battery powered, so one of the important issues in wireless sensor network is the inherent limited battery power within network sensor nodes. Minimizing energy dissipation and maximizing network lifetime are important issues in the design of sensor networks so if the power exhausted node would quit from the network, and it overall affect the network lifetime. Minimizing energy dissipation and maximizing network lifetime are important issues in the design of applications and protocols for sensor networks. In this paper there is improvement of lifetime of wireless sensor network in terms increasing alive nodes in network by using a different approach to select cluster head. The cluster head selection is based on the basis of maximum residual energy and minimum distance and chooses a optimal pat between the cluster heads to transmit to the base station.
