Embodiment Construction

[0039] The present invention utilizes the idea of ​​coverage control to realize the coverage of the critical path, and its specific implementation method is as follows:

[0040] Step 1). Carry out demand analysis on the area to be observed, conduct statistical and inductive analysis on the paths that often appear in the target, and obtain the smallest area covering all paths. In order to facilitate measurement, this area is included between two parallel curves. Measure the length and width of the curve, simplify the model on this basis, and merge the two parallel curves into one curve, which is convenient for processing and analysis;

[0041] Step 2). According to the demand analysis of step 1), deploy the wireless multimedia sensor network, estimate the number of sensor nodes covering the path, determine active nodes and dormant nodes, and initialize the sensor network;

[0042] Step 3). Waiting for the target to appear: when the target appears, the active nodes on the border...

Abstract

The invention provides a path coverage monitoring method for a wireless multimedia sensor network. A few of multimedia sensor nodes are arranged on certain key paths, and an interested object can be found in time by utilizing the cooperation of the plurality of nodes of the sensor network when the interested object appears, sleeping nodes near a moving object predication track are awakened to take part in a tracking process, so that the energy consumption of the network is considered, and meanwhile, a moving object is fully monitored. By utilizing the adjustability of the direction of the nodes in a video sensor network, the number of the nodes of a node deployment sensor is reduced, and meanwhile, a monitoring effect can be enhanced, and the energy can be saved.

Description

technical field [0001] The invention relates to the technical field of multimedia sensor network coverage control. A method based on path coverage is used to achieve complete coverage of critical paths. On the premise of maintaining complete coverage, the number of multimedia sensors is reduced as much as possible and the response speed is improved. It belongs to sensors Covers the field of control technology. Background technique [0002] With the rapid development of wireless networks and sensor devices, the types of perceptual data have also expanded rapidly, from the original single data to multimedia information such as audio, video, and images, and thus have produced a wireless network based on traditional wireless sensor networks. Multimedia sensor network. Its nodes are generally equipped with CMOS cameras, miniature microphones, and other sensors with simple environmental data collection functions. They are generally deployed in an unattended environment to complet...
