Wireless sensor network locating method

Abstract

The invention relates to a network locating method for wireless sensors, which is mainly used for solving the locating problem of each node in a wireless sensor network. The device comprises two nodes which are a beaconing node and a common node. The two nodes are respectively characterized in that: the beaconing node is provided with a GPS locating module and a wireless communicating module, andis used for receiving the GPS data transmitted by the GPS satellite network and decoding the telegraph message; a service network is made up of a plurality of beaconing nodes so as to provide locating service for the common node through the wireless communicating module; a processor module completes the GPS signal analysis and transmits the locating information through the wireless module; the common node collects the sensor data and sends the sensor data to a upper layer of node after processing; and at the same time the common node acquires the service to complete self-location from the locating network consisting of the beaconing nodes, and ensures the processing and transmitting of the locating information according to the needs.

Description

technical field [0001] The invention relates to a solution for realizing wireless sensor network node positioning, which belongs to the intersection field of embedded development and wireless communication. Background technique [0002] Wireless Sensor Network (WSN for short) is the product of the development and integration of information technology such as microelectronics technology, AdHoc wireless network, and distributed computing.
