Abstract

Different data aggregation protocols are required in wireless sensor network (WSN) to reduce computational and communication power consumption of various nodes to enhance battery lifetime of the nodes. Recent advances in WSN have led to many new protocols specifically designed to conserve the energy of the nodes and increase the lifetime of the nodes. This paper presents an overview of what WSN is and why data aggregation is required and it also focuses on reducing the power consumption of WSN by using clustered based approached protocols namely LEACH by taking certain Clustering Parameters into consideration like number of nodes, overlapping, algorithm complexity.
