Wcvaleach: Weight and Coverage Based Energy Efficient

Designing a protocol stack for wireless sensor network (WSN) is a challenging task due to energy, computational, communication and storage constraints. Energy spent for communication between sensor nodes dominates the energy spent for the computation [1]. Multi-hop short range communication between wireless sensor 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. LEACH [16], Advanced LEACH (ALEACH)[14] and Weight based energy efficient Advanced LEACH (WALEACH) [20] are energy efficient hierarchical clustering routing protocols. In this paper we presented Weight and Coverage based Advanced LEACH routing protocol WCVALEACH. WCVALEACH selects Cluster Head by assigning importance (weight) to different parameters used to select Cluster Head. It also creates the non-overlapped cluster regions to cover more number of member nodes. Both of these approaches makes WCVALEACH routing protocol energy efficient and improves life time of a wireless sensor network. Simulation results shown here verify that WCVALEACH not only improves network life time compared to ALEACH, LEACH and WALEACH algorithms but Packet Reception Rate (PRR) too.
