Barrier Coverage for 3D Camera Sensor Networks

Barrier Coverage for 3D Camera Sensor Networks

Barrier coverage, an important research area with respect to camera sensor networks, consists of a number of camera sensors to detect intruders that pass through the barrier area. Existing works on barrier coverage such as local face-view barrier coverage and full-view barrier coverage typically assume that each intruder is considered as a point. However, the crucial feature (e.g., size) of the...

Coverage Quality in Visual Sensor Networks

Barrier Coverage in Mobile Camera Sensor Networks with Grid-Based Deployment

Barrier coverage is a critical issue in wireless sensor networks for many practical applications, e.g., national border monitoring, security surveillance and intruder detection, etc. Its aim is to detect intruders that attempt to cross the protected region. Available works mainly focused on the barrier coverage of directional sensors (e.g., cameras), which have limited coverage area and sensing...

Minimum (k, ω)-angle barrier coverage in wireless camera sensor networks

Barrier coverage is an important issue in wireless sensor networks, which guarantees to detect any intruder attempting to cross a barrier or penetrating a protected region monitored by sensors. However, the barrier coverage problem in wireless camera sensor networks (WCSNs) is different from that in scalar sensor networks. In this paper, based on (k, ω)-angle coverage, we study the minimum (k, ...

An Energy Efficient Barrier Coverage Algorithm for Wireless Sensor Networks

Intrusion detection is one of the most important applications of wireless sensor networks.Whenmobile objects are entering into the boundary of a sensor field or are moving cross the sensor field, they should be detected by the scattered sensor nodes before they pierce through the field of sensor (barrier coverage). In this paper, we propose an energy efficient scheduling method based on learnin...
