The BBC does not guarantee the timeliness, completeness or performance of the website or any of the content.
In general, distributed algorithms or protocols can effectively adapt to changes in network environment and are more preferred for providing the QoS guarantee of timeliness.
But of course, this source, like all things at Guantanamo, is unpredictable, and there is no guarantee of timeliness, as Air Force lawyer, Lt. Col. Yvonne Bradley, is painfully aware.
The global aim of our project is to automate the process of creating and maintaining a problem list for hospitalized patients and thereby help to guarantee the timeliness, accuracy and completeness of this information.
The Timely Computing Base model is used as the reference model to deal with the heterogeneity of system components with respect to guaranteeing the timeliness of applications.
Then, for the purpose of satisfying the reliability metric, a QoS guaranteed forwarder list is selected from the timeliness guaranteed candidate list.
In the aspect of reducing network latency, some real-time routing protocols have been proposed [19, 20]; all these works realized soft QoS provisioning, without quantitative timeliness guarantee.
The use of a centralised planning scheduler in fieldbus-based systems requiring real-time operation has proved to be a good compromise between operational flexibility and timeliness guarantees.
We implement our control solution in a real system and present empirical results to show that our solution provides dynamic thermal and timeliness guarantees simultaneously.
While a variety of control algorithms have been proposed for either real-time guarantees or thermal management in an isolated manner, this paper proposes a coordinated control solution that can provide simultaneous thermal and timeliness guarantees for distributed real-time embedded systems running in unpredictable environments.
Section 3 presents the reliability and timeliness guaranteed opportunistic routing algorithm.
