Embodiment Construction

[0042] The following will clearly and completely describe the technical solutions in the embodiments with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Embodiments of the present invention will now be described with reference to the drawings, in which like reference numerals represent like elements.

[0043] refer to figure 1 , the embodiment of the present invention provides a kind of node localization method based on ZigBee wireless sensor network, the structure of the ZigBee wireless sensor network of present embodiment is as follows figure 2 As shown, it mainly consists of multiple anchor nodes (P1, P2, P3, P4, P5), nodes to be tested (A, B, C, D) and gateway node P. Anchor nodes (P1, P2, P3, P4, P5) are nodes with known fixed positions, responsible for positioning data packet transmission, transmission, and routing; node...

Abstract

The invention discloses a ZigBee wireless sensor network-based node positioning method. The method comprises the following steps: A1, a to-be-tested node broadcasts positioning beacon signals to the whole ZigBee wireless sensor network periodically in accordance with a specified power; A2, power of each positioning beacon signal is respectively calculated after each beach node receives the positioning beacon signals, and the calculated power and the corresponding network ID of the beach nodes are packaged into a positioning data packet which is send to the to-be-tested node; A3, the positioning data packet which is received by the to-be-tested node is integrated and then is sent to a gateway node; A4, the gateway node transmits and processes the received positioning data packet to a PC, and the PC calculates the distance between the to-be-tested node and each beach node according to power values in the positioning data packet; and A5, the PC calculates position coordinates of the to-be-tested node according to the calculated distance between the to-be-tested node and each beach node.

Description

technical field [0001] The invention relates to position positioning of a wireless sensor network, in particular to a node positioning method based on a ZigBee wireless sensor network. Background technique [0002] Wireless Sensor Network (WSN) is a popular topic in recent years. With the development of modern technology, the Internet facilitates people's life and becomes an indispensable part of people. By deploying a large number of sensors From node to target area, WSN will change the way we interact with the objective world. The emergence of wireless sensor networks is the result of the rapid development of micro-electromechanical systems, wireless communication and digital electronic technologies, and the emergence of a large number of cheap miniature sensor nodes has accelerated the development of A large number of applications of wireless sensors. The sensor network is a self-organizing system, which is a cooperative system with the ability to perceive, collect, and p...
