A Survey on Energy Efficient Data Aggregation Protocols for Wireless Sensor Networks

Wireless sensor networks (WSN) consist of several sensor nodes which sense different parameters of weather, soil, etc, and send the same to sink/base station. The sensor node has very limited battery power that is used for sensing, computing, and communication. Elimination of redundant sensed data and aggregation of nearest sensor values is necessary in order to minimize the communication overhead. Hence to conserve the battery power and thereby enhance the lifetime of a WSN, we need energy efficient data aggregation mechanisms. Our objective is to differentiate the comprehensive study of data representation model in data aggregation protocols based on energy conservation model using networks based systems. And also intends to study about the various data aggregation network based protocols in the aspects of various factor such as Aggregation Method, Resilience to Link Failure, Setup Overhead, Scalability, Resilience in case of node mobility, Energy saving method and Timing strategy.
