This paper presents a concept, architecture and an FPGA-based prototype of a smart image sensor for video cameras to be integrated into Intelligent Video Surveillance Systems. The system utilizes a distributed cooperative architecture with appropriate level of intelligence at different levels. The sensor performs automated scene analysis and provides immediate response to suspicious events by o...

Wireless Sensor Networks (WSNs) are one of the most widely used technologies in our daily lives. However, since wireless sensor networks are based on communication within radio channels, WSNs are susceptible to malicious attempts to block the channel. One of the most frequently used attacks is a jamming attack. This type of attack not only blocks the ongoing communication but also exhaust the e...

Sensor-to-symbol conversion lies at the heart of all embedded intelligent systems. The everyday world occupied by human stakeholders is dominated by objects that have symbolic labels. For an embedded intelligent system to operate in such a world it must also be able to segment its sensory stream into objects and label those objects appropriately. It is our position that development of a consist...

Ubiquitous Computing is all about how people can interact with heterogeneous devices such as computer, mobile, Personal Digital Assistants (PDAs), tabs, small sensors without explicitly instructing these gadgets and few of such gadgets are invisible to the user. Ubiquitous computing is all about to make a computer so implanted, so appropriate and so natural which fulfil every requirement of the...

The Problem: The idea of ubiquitous a computing environment where sensors and devices exist everywhere around us has opened up interesting security and privacy issues. Imagine a scenario in which Ben is working in an intelligent room. He does not want to be disturbed by anyone, so he tells the intelligent room that he does not want to be reached by anyone in the next two hours unless it is an e...

This work involves learning the use schedule of an academic building in order to intelligently control various aspects of the environment. Motion sensors are used to monitor and record the activity of each of the rooms in the building. After a basic preprocessing of the data, a Cyclic Genetic Algorithm (CGA) is used to pick out the patterns of use of the rooms. The CGA is seen as ideal for such...

The paper discusses the security issues of intelligent sensors that are able to measure and process data and communicate with other information technology (IT) devices or systems. Such sensors are often used in high risk applications. To improve their robustness, the sensor systems should be developed in a restricted way to provide them with assurance. One of assurance creation methodologies is...
