%X By analyzing various aggregation techniques and recent QoS researches in wireless sensor networks, proposed three metrics for QoS of data aggregation,which were network lifetime, data delay, and data quality respectively.Discussed and analyzed the main techniques ensuring these QoS metrics in details. It will be helpful for the research of data aggregation in wireless sensor networks.
