Wireless sensor network is a wireless network consisting of autonomous sensors, communicating with each other in dispersed manner to observe the environment. Sensors are commonly fond of to microcontroller and are power-driven by battery. Routing methods are the main issue for networks where resources are restricted. Major challenge of this type of network is to overcome the short life span due to high energy utilization of the batteries in the sensor nodes. So we are providing a routing methodology that improves that network life span and efficiency of wireless sensor network by reducing energy consumption with the proposed cluster based power saving algorithm is called as Ex-LEACH (Extended LEACH). The key idea of this paper is to decrease information transmission distance of sensor nodes in wireless sensor networks by using the homogeneous cluster Method. We calculate the average distance between the sensor nodes and take into consideration the residual energy for selecting the suitable cluster head nodes. So that the energy consumption can be equally distributed between all the sensors node by taking into consideration mainly six factors: Packet delivery ratio, Normalized routing load, End to end packet delay, Throughput, Energy Consumption, Residual Energy. The performance is compared with other similar existing protocols such as LEACH and LEACH-C routing protocols
