Sensor Parameter Estimation for Full-View Coverage of Camera Sensor Networks Based on Bounded Convex Region Deployment

Node Scheduling Strategies for Achieving Full-View Area Coverage in Camera Sensor Networks

Unlike conventional scalar sensors, camera sensors at different positions can capture a variety of views of an object. Based on this intrinsic property, a novel model called full-view coverage was proposed. We study the problem that how to select the minimum number of sensors to guarantee the full-view coverage for the given region of interest (ROI). To tackle this issue, we derive the constrai...

Coverage-Guaranteed Sensor Node Deployment Strategies for Wireless Sensor Networks

Deployment quality and cost are two conflicting aspects in wireless sensor networks. Random deployment, where the monitored field is covered by randomly and uniformly deployed sensor nodes, is an appropriate approach for large-scale network applications. However, their successful applications depend considerably on the deployment quality that uses the minimum number of sensors to achieve a desi...

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...
