Energy Efficient and Reliable WSN based on Improved Leach-R Clustering Techniques


Background/Objectives: Routing in Wireless Sensor Network (WSN) is an important area of research due to its rapidly increasing application in monitoring various kinds of environment by sensing physical phenomenon. The aim of this study is to increase the lifetime of the network. Methods/Statistical Analysis: Enhanced LEACH-R introduces the energy efficiency clustering algorithm for wireless sensor network which is based on Low Energy Adaptive Clustering Hierarchy and removed some of the limitations of the LEACH-R protocol. In this protocol we considered the advance nodes and normal nodes both but the advance nodes have more energy than the normal nodes. Results: The proposed protocol is tested virtually in MATLAB tool. All the nodes are randomly deployed in the region 100*100 m2 and base station is located at the center position i.e. (50, 50). Enhanced LEACH-R protocol gives us the better result as compared to the LEACH-R protocol in terms of energy conservation. Conclusion: This protocol improves the regions of cluster based hierarchical process using heterogeneity parameters like selection of advanced nodes (m) and additional energy factor between normal and advance nodes (a). This protocol has increased the stability time for first dead node and correspondingly the lifetime of last dead node is also increased.
