New in-network data aggregation timing mechanism in wireless sensor networks
无线传感器网络中新型的网内数据融合定时机制

Most existing data aggregation methods have a delay of the network data transmission and affect the network precision.So this paper proposed a new timing control mechanism for in-network data aggregation which divided the network induction data into real-time data and non real-time data.It achieved a better tradeoff between the network energy use efficiency and the data precision through using differentiated service for different data and configuring the timing time of node aggregation reasonably.
