Abstract

The invention relates to a wireless sensor network deployment method comprising the following steps: acquiring communication radii and sensing radii of sensor nodes, wherein the communication radii of all sensor nodes in the wireless sensor network are same, and the sensing radii of all sensor node are same; acquiring the ratio of the communication radii to the sensing radii; finding the corresponding relation of a preset optimal deployment mode, determining the normalized deployment mode corresponding to the ratio of the communication radii to the sensing radii; and deploying the sensor nodes according to the determined normalized deployment mode. In the invention, according to the preset corresponding relation between rC/rS and different normalized optimal deployment modes, after the communication radii and the sensing radii are acquired, the optimal normalized deployment mode can be quickly determined by finding the corresponding relation, thereby reducing the networking cost of the wireless sensor network.

Description

technical field [0001] The invention relates to the technical field of wireless sensor networks, in particular to a deployment method of a wireless sensor network. Background technique [0002] Wireless sensor network integrates sensor technology, microelectronics technology and wireless communication technology, and is a new information acquisition and processing technology. Among them, the deployment of nodes is the primary problem to be solved by wireless sensor network technology. In the case of ensuring the coverage and connectivity of the entire network, it is hoped that the number of nodes should be as small as possible to optimize the deployment of nodes. The normalized deployment method is an important node deployment method, and the normalized deployment refers to the mesh deployment method with equilateral geometric figures as the unit. At present, there are few studies on standardized deployment methods, and no optimized technical solutions have been proposed fo...
