Cooperative coverage method of information perception for distributed network

A cooperative coverage method for information perception of distribution network, characterized in that, comprising the following steps:

• Step 1:
• Selecting an information perception device coverage set, and prioritizing activation sorting of each information perception device in a target area according to a collation rule, then selecting the information perception device at the top of the sort to join the information perception coverage set, repeating the above prioritized activation sorting and selection process for the remaining unselected information perception devices until the entire target nodes within the target area are covered;
• Step 2:
• Connecting information perception device coverage set, the hierarchical clustering method is used to connect data processing center nodes and the information perception devices in the information perception device coverage set to realize the interconnection between the information perception devices, the information perception devices and the data processing center nodes;
• Step 3:
• Scheduling information perception device coverage set, calculating a node consumption value of the most energy-consuming information perception device in the information perception device coverage set and an aggregate energy of the information perception device coverage set, when an energy ratio between the node consumption value and the aggregate energy exceeds a scheduling threshold, the information perception device is set into a sleep state and returns to step 1 to reselect the information perception device coverage set,
• wherein in step 3, calculating the node consumption value of the most energy-consuming information perception device in the information perception device coverage set and the aggregate energy of the information perception device coverage set, the specific steps are:
• Step 3.1:
• Suppose there are m information perception devices in j-th constructed information perception device coverage set, where the remaining energy of the i-th information perception device is eri and the energy consumption per unit time segment is eit, then the number of continuous operation time slices used by the nodes of the most energy-consuming information perception device in the set is expressed as:

• from the above formula, it can be seen that the range of the number of time slices that the j-th constructed information perception device coverage set can work continuously is (0, xj];
• Step 3.2:
• The aggregate energy of the information perception device coverage set corresponds to the maximum life-cycle, then the total energy of the set is expressed as the sum of the number of work time slices of each information perception device:
