CVLEACH: Coverage based Energy Efficient LEACH Algorithm

Abstract

Designing a protocol stack for wireless sensor network (WSN) is a challenging task due to energy, computational and storage constraints. Energy spent for communication between sensor nodes dominates the energy spent for the computation [10]. Multi-hop short range communication between wireless sensors nodes is energy efficient compared to single-hop long range communication. Hierarchical clustering is one of the possible solutions to save energy of wireless sensor nodes. Low-Energy Adaptive Clustering Hierarchy (LEACH), Centralized Low- Energy Adaptive Clustering Hierarchy (LEACH-C) and Advanced Low-Energy Adaptive Clustering Hierarchy (ALEACH) are energy efficient hierarchical clustering routing protocol. In this paper we proposed Coverage based Low-Energy Adaptive Clustering Hierarchy routing protocol – CVLEACH to make uniform distribution of Cluster Heads (CHs) by creating non-overlapped cluster regions using overhearing properties of the sensor nodes, which makes the routing protocol more energy efficient and prolongs life time of a wireless sensor network. Simulation results show that CVLEACH improves network life time compared to LEACH and ALEACH algorithms.
