Abstract

The invention discloses a positioning method and device for a WSN node. The method includes determining the signal between an unknown node in the WSN and a beacon node connected to the unknown node, and determining any pixel unit in the WSN and the beacon connected to the unknown node. The signal between nodes, according to the signal between the unknown node and the beacon node connected to the unknown node and the signal between any pixel unit in the WSN and the beacon node connected to the unknown node, an objective function is generated to search for any pixel unit in the WSN The objective function value corresponding to the signal, and the pixel unit corresponding to the maximum objective function value is positioned as an unknown node. By searching the objective function value corresponding to any pixel unit signal in the WSN, and locating the pixel unit corresponding to the maximum objective function value as an unknown node, high-precision and low-power node positioning can be achieved.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a positioning method and device for wireless sensor network (Wireless Sensor Network, WSN for short) nodes. Background technique [0002] WSN is a basic component of the Internet of Things. It uses multiple sensor nodes to form a wireless network through self-organization. It is an information production and collection system used by the Internet of Things to perceive, identify, and process monitored objects in the network coverage area. With the continuous development of sensor technology, embedded computing technology, computer network technology and wireless communication technology, wireless sensor network technology has gradually matured, and has been widely used in military reconnaissance, environmental monitoring, target tracking, medical care and many other fields. universal. [0003] WSN node positioning refers to the unknown node's e...
