Embodiment Construction
[0045] In order to reduce the communication frequency of the cluster head nodes in the cluster and the communication energy consumption of each node in the cluster, the embodiment of the present invention proposes a low-energy consuming safe data fusion technology solution based on the minimum spanning tree (Low-energy Consuming Safe Data Aggregation, LCSDA), which can be applied to the Internet of Things.
[0046] The technical scheme that the embodiment of the present invention proposes comprises three stages, namely the formation stage of the cluster, the intra-cluster data fusion stage and the inter-cluster data fusion stage; wherein the first stage and the third stage are the same as the first stage in the existing LCCPDA method. The implementation process of the first stage and the third stage is basically the same. The embodiment of the present invention mainly improves the second stage (that is, the intra-cluster data fusion stage).
[0047] The low energy consumption...
