Dynamic hierarchical and distributed data acquisition algorithm
一种动态分层分布式数据采集算法

In view of the discrepancies of random acquisition order and fixed acquisition period used in the general hierarchically-distributed data acquisition algorithm, this study put forward a dynamic hierarchically-distributed data acquisition algorithm. This algorithm made use of the mobile agent to realize dynamic intra-domain acquisition of domain-topological order based on articulation, and designed the inter-domain acquisition of self-adaptable adjustment acquisition interval, thus improved the general hierarchically-distributed data acquisition algorithm. The results of the experiment prove that this algorithm can not only effectively control the traffic flow of acquisition, lighten the burden of center station and reduce the time for acquisition, but also improve the efficiency of algorithm when congestion or obstruction occurs to the network.
