The embodiment of the invention provides a dynamic network relative positioning method. The method comprises steps that the current node acquires a relative position of at least four communication nodes according to the propagation time between every two communication nodes in at least four communication nodes of the dynamic network; the current node acquires the relative position of the current node according to the relative position of the at least four communication nodes and the monitoring time difference between every two communication nodes in at least four communication nodes to the current node. According to the embodiment, through communication in pairs between at least four communication nodes, the relative position of any node in the dynamic network is acquired, a problem of lowefficiency caused by increasing of the number of the nodes in the positioning system is solved, and high-efficiency and high-precision dynamic network relative positioning is achieved.
Description
technical field [0001] The embodiment of the present invention relates to the field of communication technologies, and in particular to a dynamic network relative positioning method. Background technique [0002] In the daily production and life process, it is often necessary to measure the geographic location information of wireless devices. The more accurate the measured instantaneous phase is, the better the application effect will be. [0003] At present, there are mainly two kinds of dynamic network positioning system solutions: one is to measure the distance between several ground fixed base stations and each dynamic node, and calculate the absolute position of the positioning tag carried by the dynamic node; The dynamic nodes are equipped with mobile base stations, and the mobile base stations perform distance measurement between each other, and then upload the distance measurement information to the server in turn. [0004] In the traditional positioning network, si...
