Embodiment 1
[0065] Such as Figure 1 to Figure 3 As shown, Embodiment 1 provides a layered network charging method, including the following steps:
[0066] Step S1, constructing a layered network; and step S2, charging each sensor node in the layered network sequentially and respectively on the basis of the layered network.
[0067] Specifically, in the step S1, a layered network is constructed, that is, a layered network based on a grid structure is established in a rectangular deployment area, and each sensor node calculates its own layer number and constructs a routing path between each sensor node and the Sink node .
[0068] And in step S2, on the basis of the layered network, each sensor node in the layered network is sequentially and separately charged, that is, the charger moves along the preset trajectory and speed, and stays at the center point of each grid in turn, to provide the grid The sensor nodes in the current grid are charged, and after completing the charging of the s...
Embodiment 2
[0106] Such as Figure 1 to Figure 3As shown, on the basis of embodiment 1, this embodiment 2 provides a layered network charging system, which is suitable for establishing a layered network, and controls the charging of the charger according to the layered network Each sensor node is charged sequentially and separately.
[0107] Further, the hierarchical network charging system is suitable for establishing a hierarchical network, namely
[0108] A layered network based on a grid structure is established in a rectangular deployment area, and each sensor node calculates its own layer number and constructs a routing path between each sensor node and the Sink node; and
[0109] According to the hierarchical network control charger, each sensor node in the hierarchical network is charged sequentially and separately, that is,
[0110] The charger moves along the preset trajectory and speed, stops at the center of each grid in turn, charges the sensor nodes in the grid, and contin...
