Survey on Wireless Sensor Networks, Architecture and Protocols for Data Aggregation

Abstract

Wireless sensor networks are formed by a collection of sensor nodes which are cooperate  with each other and they send the data to the base station. Here, because of sensor nodes have limited power consumption we have to transmit the data within a limited time period. In WSN, nodes may be located far away from the base station, each node may be located far away from each other, and these nodes may have low power. To transmit the data to the base station,   we have to write the efficient data optimization techniques which take low power. In this paper we are giving the various techniques of Data aggregation and understating of these techniques & Implementation.
