Maintaining Data Freshness in Distributed Real-Time Databases
Many real-time systems need to maintain fresh views which are derived from shared data that are distributed among multiple sites. When a base data item changes, all derived views ...

A Variable Rate Execution Model
We present a task model for adaptive real-time tasks in which a task's execution rate requirements are allowed to change at any time. The model, variable rate execution (VRE)...

Static Determination of Probabilistic Execution Times
Most previous research done in probabilistic schedulability analysis assumes a known distribution of execution times for each task of a real-time application. This is however not ...

Improved Prediction for Web Server Delay Control
Control methods are being used increasingly for uncertainty management and QoS in modern web server systems. Previous approaches have suggested combined feedforward and feedback c...

Multiprocessor Energy-Efficient Scheduling with Task Migration Considerations
This paper targets energy-efficient scheduling of tasks over multiple processors, where tasks share a common deadline. Distinct from many research results on heuristics-based ener...

Schedulability-Driven Partitioning and Mapping for Multi-Cluster Real-Time Systems
We present an approach to partitioning and mapping for multicluster embedded systems consisting of time-triggered and eventtriggered clusters, interconnected via gateways. We have...

Managing Quality-of-Control Performance Under Overload Conditions
A common method for dealing with overload conditions in periodic task systems is to reduce the load by enlarging activation periods. When a periodic task implements a digital cont...

A New Sufficient Feasibility Test for Asynchronous Real-Time Periodic Task Sets
The problem of feasibility analysis for asynchronous periodic task sets (i.e. where tasks can have an initial offset) is known to be co-NP-complete in the strong sense. A sufficie...

Comparing Real-Time Communication Under Electromagnetic Interference
The contribution of this paper is threefold. First, an improvement to a previously published paper on the timing analysis of Controller Area Network (CAN) in the presence of trans...
