Embodiment Construction

[0075] Embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0076] Embodiments of the present invention provide a distributed sensor network, such as figure 1 shown. Including the sensor node to be positioned 1, the sensor node to be positioned 2, the sensor node to be positioned 3, and the anchor sensor node 4, the above sensor nodes form a distributed network of wireless sensors, the purpose of this embodiment is to determine 1, 2, The specific location of the No. 3 sensor node to be located. The distributed positioning device based on the game method proposed in this embodiment can be installed in any type of sensor node to be positioned. For example, the current general-purpose TelosB type sensor node can meet the requirements.

[0077] Distributed positioning devices based on the game method are all set in the above-mentioned No. 1, 2, and 3 sensor nodes to be positioned, such as figure 2 shown...

Abstract

A distributed positioning device and method based on a game method in a wireless sensor network, belonging to the field of wireless sensor positioning technology. Node status getter, measured distance calculator, neighbor node set builder, anchor node information filter, location policy space generator, node location calculator, threshold setter, comparator node converter and node status broadcaster. The present invention only needs to communicate and negotiate with neighbor nodes during the positioning process, which can greatly reduce the load overhead of positioning and save energy consumption in the positioning process. Furthermore, by negotiating with the anchor neighbor node before the game starts to determine the game strategy space, and using the number of consecutive precise positionings to determine the precise positioning conditions, the rapid convergence of the positioning algorithm can be accelerated. The method of the present invention can quickly and effectively position the sensor node accurately. Location, it also performs well in environments with high density and a small number of anchor node deployments, and has good scalability.

Description

technical field [0001] The invention belongs to the technical field of wireless sensor positioning, and in particular relates to a distributed positioning device and method based on a game method in a wireless sensor network. Background technique [0002] The wireless sensor network consists of a large number of micro, low-energy, and low-cost sensor nodes deployed in the monitoring area, and forms a self-organizing multi-hop network system through wireless communication. Node positioning is an important prerequisite for the smooth development of most wireless sensor network applications. Applications such as environmental monitoring, target tracking, mine information collection, and disaster rescue essentially require the ability to quickly and accurately obtain the location information of each sensor node. In addition, accurately providing the location information of each sensor node can also help to enhance the quality of network coverage, improve network topology self-co...
