The development of distributed real-time systems often relies on clock synchronization. However, achieving precise synchronization in the field of Wireless Sensor Networks (WSNs) is hampered by competing design challenges, such as energy consumption and ...

This paper introduces an innovative closed-loop traffic controller to efficiently and fairly share a single common resource, e.g., the available bit rate in a wireless link, among a set of traffic flows characterized by different Quality of Service (QoS)...

Fault tolerance is an important aspect in real-time computing.In real-time systems, tasks could be faulty due to various causes. Faulty tasks may compromise the safety and performance of the whole system and even cause disastrous consequences. In this ...

The rapidly increasing scale of computing systems means that it is vitally important to address the scaling challenges in the control of computing systems. We introduce a framework for describing the control problems for large scale computing systems ...

Cfengine is an autonomous agent for the configuration of Unix-like operating systems. It works by implementing a hybrid feedback loop, with both disrcete and continuous elements.

We present a framework for estimating the service time of a dynamic HTTP request by using the service times of past requests to the same URL. Our framework tags incoming requests with a timestamp. As the request is processed, server state relevant to ...

This paper describes a method for finding the stability regions of the PI and PIP controllers for TCP AQM with delays. The method is applied on several representative examples, showing that stable controllers can exhibit widely different performance. ...
