The use of sensing technologies in industrial environments has opened many possibilities for monitoring and control applications, driving much research efforts in the last years. Among the challenging issues related to industrial wireless sensor networks, efficient nodes deployment is a major concern since it can directly impact the way sensors operate, which has demanded proper solutions. When sensing...
Visual sensors can be used to retrieve still images or video streams in a large set of monitoring applications, providing valuable information of the monitored environment. In fact, camera-enabled sensors are directional and the viewed area depends on their orientations. As the positions and orientations of the embedded cameras may not be optimal after deployment, the area viewed by sensors may be...
In wireless visual sensor networks comprised of multiple camera-enabled sensors, source prioritization can be exploited to soften the impact of congestion, packet loss and energy depletion when higher relevant packets are processed. However, for such optimizations, source nodes have to be properly prioritized according to some effective metric. When performing visual sensing over moving targets, sensors...
