Wireless sensor networks have seen thriving development and its increased usage has made it a keen topic for researchers to explore more. Huge investments and research efforts are going on in this field. It has been used for the purpose of sensing and communicating data without any supervision of human being. There are various areas where research activities are going on in Wireless sensor networks. These are deployment , localization , Synchronization , Calibration , DataAggregation and Data Dissemination , Security , Middleware, Database Centric and Querying,etc. One of popular area of interest is optimizing strategies of routing protocols with respect to energy utilizationof sensor nodes. Custering mechanism is one of the popular WSNs routing mechnisms. In this paper we have proposed a new enhanced MODLEACH protocol after analysing the previous MODLEACH algorithm. The result shows that the network lifetime and rate of transfering packets to BS have improved
