Analysis of Data Aggregation Techniques in Wireless Sensor Networks (original) (raw)

The main goal of data aggregation algorithms is to gather and aggregate data in Wireless Sensor Network (WSN) in an energy efficient manner so that network lifetime is enhanced. Data aggregation may be effective technique in this context because it reduces the number of packets to be sent to sink by aggregating the similar packets. The performance of data aggregation protocols are characterized by performance measure such as energy consumption, latency ad data accuracy. In this paper, we present a survey of data aggregation algorithms and approaches for handling the trade-offs in data aggregation schemes.
