ENERGY-EFFICIENT CLUSTERING PROTOCOLS FOR WIRELESS SENSOR NETWORKS:A SURVEY

Abstract

In Robotics and telecommunications world, wireless sensor networks are an active research area with numerous real life applications, R&D and industrial area. Wireless Sensor Networks consist of small nodes with sensing, computation, and wireless communications capability. Wireless sensor networks (WSNs) have been widely deployed for various applications, such as environment sensing, Military, Medical, Traffic Monitoring, Habitat Monitoring, building safety monitoring, earthquake prediction. In general WSN architecture, storage nodes aggregate data from nearby sensors and answer queries from the sink of the network which is also called as two-tiered WSN architecture. In past many routing, power management, and data scattering protocols have been specifically designed for WSNs, where energy awareness is an essential design concern. In many system data direction-finding in Network Aggregation for WSN’s is done by the routing tree finding the shortest path from the source node to sink node while maximizing data aggregation. If one of the nodes failed the repairing route is time consuming and energy consuming process.
