摘　　要：研究现有数据融合算法无法满足网络动态变化频繁和数据通信可靠性要求高的新应用需求的问题,提出一种无结构动态适应的数据融合算法,将网络划分为若干个栅格,传感器以栅格为单位进行数据通信并采用"多对多"的数据通信方式,传感器之间无需建立和维护结构。仿真实验结果表明,算法在实现数据融合的同时,能够适应网络的动态变化、提供高可靠性的数据通信。Researches on the problem that the existing data fusion algorithms couldn’t satisfy the new application re-quirements,ie,frequent dynamic change of network and high demand with reliability of data communication,a struc-ture-free and dynamic-adaptive data fusion algorithm was presented which divided the network into several grids,sensors perform data communication according to grids and adopt many-to-many data communication manner,there was no need for sensors to establish and maintain a structure.The results of simulation experiments show that this algorithm is able to adapt the dynamic change of network and offer high reliable data communication while performs the task of data fusion.
