Embodiment 1
[0061] Embodiment 1: as Figure 1-9 As shown, a virtual force-based sink node relocation method includes the following steps:
[0062] Step1. When the network starts, the sink node s collects the position and remaining energy information of all nodes. The specific steps are:
[0063] Step1.1. Establish a virtual gravity model
[0064] All sensor nodes have a virtual gravitational force on the sink node s, which is just like universal gravitation, so according to the universal gravitational force in physics The formula analogy obtains the virtual gravitational model of sensor node i where a i and a respectively represent the remaining energy of node i and sink node s, because the energy of sink nodes is generally regarded as infinite and it does not consume energy, so a is a constant and can be merged into k A , and then calculate the virtual gravitational force between node i and sink node s, namely:
[0065]
[0066] where k A is a constant representing the virtual...
