Quad Clustering Routing Protocol to Enhance the Stability in WSN

Sharath S.T, Veena N

A WSN (Wireless Sensor Network) can be used as effective tool for sensing and collecting data in various platforms using huge number of wireless sensor nodes. The main concern in wireless sensor networks is to develop the efficient energy routing protocol which increases the lifetime of the sensor nodes. This paper focuses on lessening the energy consumption and enhances the throughput and stability period of wireless sensor networks. Therefore, a communication protocol named Q-LEACH is modified. We propose that the network area is divided into four quadrants and each quadrant has equal number of sensor nodes (cluster), CH (Cluster Head) and Sub-CH (acts as CH when original CH expires before completion of round). We have simulation based results to compare the performance with existing protocol LEACH (Low Energy Adaptive Cluster Hierarchy) and proposed protocol QLEACH. The outcome of the experiment shows that Q-LEACH protocol has greater degree of NLT (Network Life Time) in the network against the LEACH protocol.
