Embodiment Construction
[0040] The present invention will be further described below in conjunction with the accompanying drawings, so as to further explain the technical features and advantages of the method of the present invention. However, embodiments of the present invention are not limited thereto.
[0041] The present invention provides a high-precision anchor-free positioning method, and the specific implementation steps are as follows:
[0042] 1. Initialize the network
[0043] Suppose there are N sensor nodes in the global network, each sensor node has its own unique ID, all sensor nodes have the same communication range, and the maximum communication radius is R. The distance measurement information can be obtained between sensor nodes through ranging technology (ranging technology can use received signal strength indication (RSSI), time difference of arrival (TDOA), time of arrival (TOA), angle of arrival (AOA), etc.). Each sensor node sends location information, ID information and mea...
