Wireless sensor network (WSN) is used for a large number of sensor nodes and energy efficiency is important to constrained resources in wireless sensor networks. Wireless sensors networks use multiple approaches such as data cycling, energy optimal scheduling and energy aware routing to reduce energy consumption throughout the network. Energy awareness is an essential design for WSNs hence, data broadcasting protocols, routing and power management are specially designed to meet their requirements. The past decade was mitigating the issues of energy dissipation to ensure energy efficient routing and clustering. To address these issues, a novel idea is presented where the energy efficiency will incorporate the selection mechanism of nodes. In Wireless Sensor Networks, path routing for nodes is a difficult and tricky task. It is a crucial role to increase the stability and network lifetime. The LEACH Protocol is a measured level of the sensor networks lifetime by pairing the node energy consumption. Simulation results show that protocol outperform its routing protocols Low Energy Adaptive Clustering Hierarchy (LEACH) and Novel-LEACH in terms of network connectivity and power consumption. Also, a new energy efficient clustering scheme for WSNs with the use of Particle Swarm Optimization (PSO) is proposed. The clustering algorithm is implemented with the goal of concurrently minimizing the intra-cluster distance along with optimizing the usage of network energy.
