An SVM-based secure access method for wireless terminals. Step 1, establish a wireless network security model based on the communication scenarios of the wireless terminal and the wireless base station; establish the channel feature vectors based on the wireless network security model and the frames received by the wireless base station; Step 2, use the pre-trained SVM model to examine the channel feature vectors of the frames, determining whether the frames are legitimate signals; Step 3, determine whether the wireless terminal with at least one frame sent is a legitimate terminal based on whether at least one of the frames sent is a legitimate signal. The frames sent by the wireless terminals that access the wireless base station are examined to effectively determine legitimate terminals by improving the SVM parameter combination optimization method of differential evolution and the differential evolution method with an adaptive improvement of the control parameters.

This invention provides a cooperative coverage method for distribution network information perception. The cooperative coverage method includes the following steps: construction of connected cooperative coverage sets, which can cover all target nodes with as few information perception nodes as possible, and maintain the connectivity of each cooperative coverage set with connected sets construction methods based on of hierarchical clustering; Cooperative coverage set scheduling, introducing the concept of energy ratio threshold, dividing the life cycle of the system into multiple time slices, calculating the energy ratio of perception device set in each time slice to realize the set scheduling. The invention realizes the efficient utilization of the energy of the perception device through the construction and scheduling of the connected coverage set in different time slices, and improves the use efficiency of the information perception network.
