Embodiment Construction
[0049] A fault recovery method for a wireless sensor network proposed by the present invention will be described in detail below with reference to the drawings and embodiments.
[0050] First of all, it should be noted that the abbreviation as "node" in the following content refers to transposed nodes.
[0051] Refer below Figure 1 ~ Figure 3 Introduce each step separately:
[0052] 101) Divide connected sets (Connected Set, CS). In order to move the transposed nodes of each isolated region to the CS closest to itself, the positions of these CSs need to be determined according to the distribution density of the nodes. In the present invention, CS is defined as a concentric circle with the geometric center point of the network monitoring area as the center, so determining the position of CS is to determine the radius value R of the concentric circle, wherein the initial value of R is the largest concentric circle (i.e. the farthest isolated The circle where the area is loca...
