Context-aware reconfiguration of large-scale surveillance systems: argumentative approach
The Metis research project aims at supporting maritime safety and security by facilitating continuous monitoring of vessels in national coastal waters and prevention of phenomena, such as vessel collisions, environmental hazard, or detection of malicious intents, such as smuggling. Surveillance systems such as Metis typically comprise a number of heterogeneous information sources and informatio...
متن کاملValidating for Liveness in Hidden Adversary Systems
Multi-stream interactive systems can be seen as “hidden adversary” systems (HAS), where the observable behaviour on any interaction channel is affected by interactions happening on other channels. One way of modelling HAS is in the form of a multi-process I/O automata, where each interacting process appears as a token in a shared state space. Constraints in the state space specify how the dynam...
متن کاملOcclusion-aware multi-UAV surveillance
We present an agent-based coordination and planning method for autonomous aerial surveillance of multiple urban areas using a group of fixed-wing unmanned aerial vehicles (UAVs). The goal of the surveillance is to observe a set of ground points of interest within the target areas as often as possible. The method differs from the existing work by explicit consideration of sensor occlusions that ...
متن کاملDistance-Aware Beamforming for Multiuser Secure Communication Systems
Typical cryptography schemes are not well suited for low complexity types of equipment, e.g., Internet of things (IoT) devices, as they may need high power or impose high computational complexity on the device. Physical (PHY) layer security techniques such as beamforming (in multiple antennas systems) are possible alternatives to provide security for such applications. In this paper, we consid...
متن کاملContext-aware systems: concept, functions and applications in digital libraries
Background and Aim Among the places that context-aware systems and services would be very useful, are libraries. The purpose of this study is to achieve a coherent definition of context aware systems and applications, especially in digital libraries. Method: This was a review article that was conducted by using Library method by searching articles and e-books on websites and databases. Results:...
