The invention provides a wireless sensor network node positioning method. The method includes the following steps that (1) two movement anchor nodes AN and RN parallelly randomly linearly move in a sensing area, the AN and the RN periodically and simultaneously broadcast, the AN broadcasts position coordinates information, and the RN broadcasts reference information; (2) an unknown node compares simultaneously received AN and RN broadcasted signal strength, and coordinates information of weakest and strongest AN signals is recorded; (3) the unknown node obtains a high-low string according to the coordinates information of the weakest and strongest AN signals, and coordinates O and O' of two circle centers which pass through the string are figured out; (4) the unknown node determines the position relation of the coordinates of the circle center O in the high-low string, results and directional information of the high-low string are compared by combination of AN and RN signal strength, and finally, the O and the O' are selected as positioning results of the unknown node.
Description
technical field [0001] The invention relates to the field of wireless sensor network positioning, in particular to wireless sensor network single-chord positioning with dual mobile anchor nodes. Background technique [0002] Wireless sensor network (WSN) is used to monitor the characteristics of various environments in the network deployment area, and is mainly used in scenarios such as military reconnaissance and natural environment index monitoring. A wireless sensor network consists of a large number of stationary or mobile sensor nodes in a self-organizing and multi-hop manner to form a wireless network, which uses cooperative perception, collection, processing and transmission of the information of the perceived object in the geographical area covered by the network, and finally transfers the information Sent to the owner of the network. [0003] A large number of sensor nodes in wireless sensor networks are often randomly deployed in the monitoring area, and various p...
