Energy reduction is critical to increase the mobility and battery life for today’s pervasive computing systems. At the same time, energy reduction must be subject to the realtime constraints and quality of service (QoS) requirements for multimedia applications running on these systems. This paper presents a novel run-time scheduling approach to reduce the system-wide energy consumption for such...

This paper focuses on the Firm Real-Time requirements of Time-Critical Wide Area Measurement and Control systems, that are expected to play a major role in future Smart Grids. It analyses the operation of these systems and identifies their communication traffic characteristics. It shows that these characteristics are significantly different to those of the current Near Real-Time Wide Area Measu...

Several real-time applications, such as E-commerce, multimedia and process control are subject to multiple criteria scheduling problems. In such systems service differentiation and quality of service (QoS) guarantees are necessary. Often the multi-class task model can be associated to multiple (m,k)-firm constraints indicating the degree of missed deadlines that the system can tolerate for each...

This paper establishes a link between three areas, namely Max-Plus Linear System Theory as used for dealing with certain classes of discrete event systems, Network Calculus for establishing time bounds in communication networks, and real-time scheduling. In particular, it is shown that important results from scheduling theory can be easily derived and unified using Max-Plus Algebra. Based on th...

MITRE'S Evolvable Real-Time Comma& Control, and Communications (C3) project funa'ed under the Air Force Mission Oriented Investigation and Experimentation (MOIE) program attempts to develop an approach that would enable current real-time systems to evolve into the systems of the future. The project has chosen Airbonze Warning and Control System (AWACS) as an example to test the concepts and arc...

vehicle detection and classification of vehicles play an important role in decision making for the purpose of traffic control and management.this paper presents novel approach of automating detecting and counting vehicles for traffic monitoring through the usage of background subtraction and morphological operators. We present adaptive background subtraction that is compatible with weather and ...
