| Abstract: | The use of Wireless Sensor Networks (WSNs) is anticipated to bring enormous changes in data gathering, processing and dissemination for different environments and applications. However, a WSN is a power constrained system, since nodes run on limited power batteries which shorten its lifespan. Prolonging the network lifetime depends on efficient management of sensing node energy resource. Energy consumption is therefore one of the most crucial design issues in WSN.
Hierarchical routing protocols are best known in regard to energy efficiency. By using a clustering technique hierarchical routing protocols greatly minimize energy consumed in collecting and disseminating data. Low Energy Adaptive Clustering Hierarchy (LEACH) is one of the fundamental protocol in this class.
In this research project, we propose a more energy efficient routing algorithm here-in referred to as Hierarchical LEACH (H-LEACH). H-LEACH extends LEACH clustering approach. We focused mainly on energy usage and end-to-end performance characteristics of both algorithms.
The simulation results demonstrated that H-LEACH is more energy efficient, implying that it is more effective in prolonging the network life time compared to LEACH. |
