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 angles. In this paper, the authors study how to efficiently improve barrier coverage using mobile camera sensors, where camera sensors are deployed by a grid-based strategy.
