%X Aiming the severe energy and computing resource constraints of wireless sensor networks, data aggregation is an important approach that assists it in decreasing the energy consumption, eliminating data redundancy, increasing the energy efficiency of the useful information flow from the source to the sink and extending the network lifetime. Data aggregation can be incorporated with routing protocols or can be implemented as individual protocols/techniques that interact closely with routing protocols. Firstly, the backgrounds of aggregation were introduced. Then the main aggregation techniques were analyzed and reviewed, including aggregation routings, aggregate functions and data mining. Finally, the future rescarch directions of data aggregation in wirelcss sensor network were pointed out.
