This paper proposes an anomaly detection framework that utilizes key performance indicators (KPIs) and traffic measurements to identify in real-time misbehaving mobile devices that contribute to signaling overloads in cellular networks. The detection algorithm selects the devices to monitor and adjusts its own parameters based on KPIs, then computes various features from Internet traffic that c...

To cope with the increasing demand of wireless communication services multi-carrier systems are being used. Radio resources are very limited and efficient usages of these resources are inevitable to get optimum performance of the system. Paging channel is a low-bandwidth channel and one of the most important channels on which system performance depends significantly. Therefore it is vulnerable ...

Research in the area of power system, incorporating optimal power flow and optimal load shedding, has been used in classical dispatch problems to determine control adjustments to remove line overloads. This paper reports a rule-based load shedding in a ship power system. To filter critical outages and congestion cases, a load shedding rule-based system is implemented. The algorithm searches for...

Recent results in the application of scheduling theory to dependable real-time systems are reviewed. The review takes the form of an analysis of the problems presented by different application requirements and characteristics. Issues covered include uniprocessor and multiprocessor systems, periodic and aperiodic processes, static and dynamic algorithms, transient overloads and resource usage. P...

THE establishment of a fistulous tract between the aorta and the right ventricle poses critical problems in cardiopulmonary dynamics. The higher aortic pressure drives an excessive flow of blood into the right ventricle and overloads it. The increased pulmonary arterial pressure and blood flow lead to pulmonary edema and right heart failure, thereby precipitating a fulminating course and early ...

In this paper, we analyze overload control for composite web services in service oriented architectures by an orchestrating broker, and propose two practical access control rules which effectively mitigate the effects of severe overloads at some web services in the composite service. These two rules aim to keep overall web service performance (in terms of end-to-end response time) and availabil...

In the national airspace system, sectors get overloaded due to high traffic demand and inefficient airspace designs. Overloads can be eliminated in some cases by redesigning sector boundaries. This paper extends the Voronoi-based sector design method by automatically selecting the number of sectors, allowing three-dimensional partitions, and enforcing traffic pattern conformance. The method was...

We present the first Utility Accrual (or UA) real-time scheduling algorithm for multiprocessors, called gMUA. The algorithm considers an application model where real-time activities are subject to time/utility function time constraints, variable execution time demands, and resource overloads where the total activity utilization demand exceeds the total capacity of all processors. We establish s...

The successful functioning of telecommunication networks largely depends on the effectiveness algorithms for detection and protection against overloads. article describes main differences that arise when forecasting, monitoring managing congestion at node level channel level. An algorithm detecting by estimating entropy time distributions traffic parameters is proposed. measures data sets vario...
