Wireless Sensor Networks have been increasingly with the use of advanced methods to develop these kinds of networks in various fields like biometrics, weather monitoring, military applications etc. Wireless Networks are deployed in various regions and one of the key issues is that, the sensor nodes are largely dependent on the batteries which are fitted in them at the time of installation. In most of the cases the sensor nodes have to be largely dependent on the fixed non rechargeable batteries. Thus it is for utmost importance to save the energy as much as possible and preserve the network energy and hence its lifetime. There have been several routing protocols designed and all are primarily focused to provide maximum network lifetime by ensuring the efficient use of sensor node energy. Among these protocols the clustering based protocols are the most widely used and are extensively researched to devise new routing protocols to preserve the network energy. In this research work the main focus is to study the various available clustering based routing protocols and observe their rules and features. An attempt is also made to devise a new protocol based on Fuzzy Based Stable Election Protocol for heterogeneous networks. A simulated virtual environment is envisaged to be built in MATLAB to understand the network setup and implement the algorithm for an energy efficient routing. A number of protocols have been studied in depth in this research work. The proposed protocol have shown improvement in number of dead nodes and average energy per node as compared to the existing SEP protocol when a comparative study was done on similar simulation parameters on both the methods.
