Abstract

The invention relates to a networking method of a wireless grid sensor based on link stability estimation, in particular to a networking method of a wireless sensor network to solve the problems that the network throughput is low, the network time delay is high and the protocol expenditure is high caused by that the original sensor networking method cannot utilize geographic location information to carry out link estimation by local nodes. The wireless sensor network is divided into grids; when a data group of one sensing node or a relay node needs to be sent to a center node, a sending direction of the group is initially selected according to relative position information between the sensing node or the relay node and the center node and all the alternative relay nodes are listed; and link stability information of all the alternative relay nodes in the direction is estimated by estimating the link stability information of a sending node and the relay nodes in the grids by the sending node according to the relative position information between the sending node and the adjacent grids in the selected direction. The method provided by the invention is used for establishing a network.

Description

technical field [0001] The invention relates to a wireless sensor network networking method. Background technique [0002] The background technology adopted in the application of the present invention can be summarized as the following points: 1) multi-hop wireless relay technology; 2) low-overhead network transmission technology; 3) fault-tolerant technology based on link stability; 4) ID-based addressing technology ; 5) Static network efficient networking technology. [0003] Nodes in wireless sensor networks are usually composed of wireless transceiver devices with very limited communication performance due to cost and volume constraints. These devices transmit the various monitoring signals collected to the remote central node by means of multi-hop relay transmission, so as to jointly complete the monitoring task of a specific environmental parameter. Common monitoring objects include air pollutants and humidity. , temperature, and the electromagnetic spectrum. Wirele...
