无线传感器网络中新型的网内数据融合定时机制*

大部分现有的数据融合策略都会给网络数据的传输造成很大的延迟，影响网络的精确性。为此，提出了一种新型的网内数据融合定时控制机制。它将网络中感应数据划分为实时数据和非实时数据，通过对不同数据采用的区分服务，对节点的融合定时时间进行合理配置，取得了网络能量利用效率与数据精确性之间的良好折中。

New in network data aggregation timing mechanism in wireless sensor networks

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.
