The invention provides a non-range-finding underwater wireless sensor network node positioning method and a system. The non-range-finding underwater wireless sensor network node positioning system comprises a data acquisition apparatus and a data processing apparatus, the data acquisition apparatus comprises a plurality of unknown nodes and a plurality of beacon nodes, and the data processing apparatus comprises a plurality of sink nodes. After a first unknown node and a second unknown node are directly located by employing the beacon nodes, and the located first unknown node and the second unknown node are regarded as the new beacon nodes to participate in the locating of the remaining unknown nodes as a first new beacon node and a second new beacon node. According to the method and the system, the quantity of the unknown nodes which cannot be located can be effectively reduced, the time required by the locating of the unknown nodes is shortened, the energy consumption of the system is reduced, and the method and the system are especially applicable to the underwater wireless sensor network with sparse deployment of the beacon nodes.
Description
technical field [0001] The invention relates to the field of wireless sensor networks, in particular to a non-ranging-based underwater wireless sensor network node positioning method and system. Background technique [0002] Wireless sensor network (WSN) integrates intelligent sensor, microprocessor and wireless communication technology, and is a comprehensive subject with great research and practical value. According to different application environments, it can be divided into terrestrial wireless sensor networks and underwater wireless sensor networks.
