Abstract: Wireless sensor networks (WSNs) are self-organised, low cost and low power utilising network, which senses, calculates and communicates the data from the source to sink. The data collection at sensor nodes consumes more energy, but the sensor nodes have only limited energy. Hence, most of the data-aggregation techniques aim to prolong the lifetime of the network by minimising power consumption and optimised data transmission. In this paper, an extensive survey of various data aggregation techniques in WSN is performed by categorising the techniques as structured, structure-free, flat and hierarchical. These techniques are analysed in terms of energy conservation, network lifetime, packet delivery ratio, latency and various other parameters. A comparison of these data aggregation techniques is also presented along with their advantages and issues.
Keywords: wireless sensor networks; WSNs; data aggregation; privacy preservation; privacy protection; network security; energy conservation; network lifetime; packet delivery ratio; latency.
