Abstract

The invention discloses a method for judging strong barrier coverage of a directed sensor network in the technical field of wireless communication, which is used for solving the problem of researching existence of the strong barrier coverage of the traditional directed sensor network. The method comprises the steps of: randomly deploying directed sensor nodes, wherein the directed sensor nodes self-recognize to form a directed sensor network through a broadcasting manner; generating a virtual node for each directed sensor node by a sink node, wherein the virtual node also has a perceptive direction and a perceptive region; constructing a directed coverage connected graph by the sink node according to the generated virtual nodes and two virtual boundary nodes; and traversing the directed coverage connected graph by the sink node and judging whether the directed sensor network meets the strong barrier coverage. According to the invention, the limits of simple assumption, large computation and the like of the traditional judging method in practical application are overcome, and the judgment of the strong barrier coverage of the directed sensor network is effectively realized.

Description

technical field

[0001] The invention belongs to the technical field of wireless communication, in particular to a method for judging strong fence coverage of a directed sensor network. Background technique

[0002] The coverage control of the sensor network aims to achieve different management or sensing effects on the monitoring area through the cooperation of various sensor nodes, which is the premise and basis for the effective implementation of the entire environmental monitoring task. As one of the research hotspots of sensor network coverage control theory, barrier coverage mainly studies how to allocate network space-time resources to ensure that any moving target can be monitored when it passes through the monitoring area along any path. The goal of this type of coverage control problem is to find one or more paths connecting the left and right boundaries such that such paths provide different sensing / surveillance qualities for moving targets under different model de...
