Barrier coverage in wireless camera sensor networks (WCSNs) has drawn the attention of research community since it promises an extremely large potential applications involve movement detection and surveillance. As battery resources are limited, improving efficiency energy is one key drivers for prolonging lifetime barrier coverage. However, most prior studies on this problem only worked with ho...

Visual sensor networks have emerged as an important class of sensor-based distributed intelligent systems, with unique performance, complexity, and quality of service challenges. Consisting of a large number of low-power camera nodes, visual sensor networks support a great number of novel vision-based applications. The camera nodes provide information from a monitored site, performing distribut...

technology advancement improves the way we interact with computer systems. keyboard, mouse, and touchpad provide an easier and more natural way of interaction with a computer system. nowadays, by introducing low cost and high performance depth cameras like kinect and xtion, new opportunities are available for creating even more natural interfaces. in this paper, a new model was demonstrated for...

Fieldbus communication networks aim to interconnect sensors, actuators and controllers within distributed computer-controlled systems. Therefore, they constitute the foundation upon which real-time applications are to be implemented. A specific class of fieldbus communication networks is based on a simplified version of tokenpassing protocols, where each station may transfer, at most, one Singl...

Modern navigation, mapping and surveillance systems require numerous cameras mounted at random locations over a geographically large area. In order to efficiently extract any location-specific intelligence from such a large network of cameras, we propose to create distributed look-up tables that rank the cameras according to how well they can image a specific location. The look-up table covers ...
