H-LEACH: Modified and Efficient LEACH Protocol for Hybrid Clustering Scenario in Wireless Sensor Networks

Wireless sensor networks consist of independent sensors that sense and monitor the area of deployment and distributedly communicate this information to base station. The desirables of WSN are to have long longevity and high reliability along with maximized coverage. LEACH is one of the most discussed hierarchical, cluster-based routing protocols for sensor networks owing to its load-balancing characteristics. In this paper, we have presented a hybrid approach (H-LEACH) in which the clusters are fixed, but the cluster heads are chosen dynamically. The approach shows an improved performance that is duly supported by the simulation results using MATLAB. The paper concludes with the limitations and further scope for improvement in the proposed protocol.
