Abstract: Wireless Sensor Networks (WSN) refers to the collection of autonomous sensor nodes deployed over an area. Sensor nodes usually employ batteries as sources of power, having little energy resources, and hence make energy efficiency an essential issue in designing a WSN routing protocol. This research paper offers a complete evaluation of some of the energy efficient routing protocols for Wireless Sensor Network, which includes clustering, hierarchical clustering and location aware routing. In particular, four energy efficient protocols, namely, Low-Energy Adaptive Clustering Hierarchy (LEACH), Power-Efficient Gathering in Sensor Information Systems (PEGASIS), Threshold Sensitive Energy Efficient Network (TEEN), and recently developed hybrid energy efficient distributed clustering routing protocol (HEED) have been evaluated using the NS-3 Simulator, with 500-node simulation. Simulation results indicate that HEED consumes 32% lesser energy than LEACH and has an extended lifetime by 28%.
