Architectural Based Data Aggregation Techniques in Wireless Sensor Network: A Comparative Study

Data aggregation is very crucial techniques in wireless sensor network. Because with the help of data aggregation we reduce the energy consumption by eliminating redundancy .when wireless sensor network deployed in remote area or hostile environment. In the wireless sensor network have most challenging task is life time so with help of data aggregation we can enhance the lifetime of the network .In this paper we discuss the architectural based efficient data aggregation. And also discuss the protocol based network architecture. Keywords— wireless sensor network, data aggregation, architecture
