Abstract: In this fast forward world, we require all the information instantly . In some areas, Wireless Sensor Network is helping us to get this information. In aa thousand of cheap micro-sensor nodes allows a user to monitor a remote environment for civil as well as a military application from the main station. The data collected by micro-sensors is communicated through a network to a single sink node. For this communication first cluster sensors into groups, and via cluster head they will communicate to a sink node. Major energy Is getting consumed while communicating with the sink node resulting the sensors life become very short. This consumption of energy is not advisable, and also at the remote place it is very difficult to replace the battery of thousands micro sensor. To solve all these issues the algorithms has been invented . For effective balances cluster head and prolonged network lifetime, there is a novel uneven clustering scheme invented by Qi Zhang(2). By considering residual energy and distance from the sink node the modified algorithm has given a better performance. The same algorithm is called Distance and Energy Based Uneven Clustering (DEUC). By changing the method of selection of cluster head and also changing the probability factor modified DEUC algorithm gives a better performance than the previous one. The modified algorithm improves the lifetime of the node also the energy of the network.
