Adaptive packet scheduling over a wireless channel under constrained jamming
Fernández Anta, Antonio; Georgiou, Chryssis; Kowalski, D. R.; Zavou, Elli (2017)In this work we consider the communication over a wireless link, between a sender and a receiver, being disrupted by a jammer. The objective of the sender is to transmit as much data as possible to the receiver in the most ...

Adaptive scheduling over a wireless channel under constrained jamming
Fernández Anta, Antonio; Georgiou, Chryssis; Zavou, Elli (2015)We consider a wireless channel between a single pair of stations (sender and receiver) that is being “watched” and disrupted by a malicious, adversarial jammer. The sender’s objective is to transmit as much useful data as ...

Competitive analysis of fundamental scheduling algorithms on a fault-prone machine and the impact of resource augmentation
Fernández Anta, Antonio; Georgiou, Chryssis; Kowalski, Dariusz R.; Zavou, Elli (2018)Reliable task execution in machines that are prone to unpredictable crashes and restarts is both challenging and of high importance, but not much work exists on the analysis of such systems. We consider the online version ...

Measuring the impact of adversarial errors on packet scheduling strategies
Fernández Anta, Antonio; Georgiou, Chryssis; Kowalski, D. R.; Widmer, J.; Zavou, Elli (2013)In this paper we explore the problem of achieving efficient packet transmission over unreliable links with worst case occurrence of errors. In such a setup, even an omniscient offline scheduling strategy cannot achieve ...

Measuring the impact of adversarial errors on packet scheduling strategies
Fernández Anta, A.; Georgiou, Chryssis; Kowalski, D. R.; Widmer, J.; Zavou, Elli (2016)In this paper, we explore the problem of achieving efficient packet transmission over unreliable links with worst-case occurrence of errors. In such a setup, even an omniscient offline scheduling strategy cannot achieve ...

Online parallel scheduling of non-uniform tasks: Trading failures for energy
Fernández Anta, Antonio; Georgiou, Chryssis; Kowalski, D. R.; Zavou, Elli (2015)Consider a system in which tasks of different execution times arrive continuously and have to be executed by a set of machines that are prone to crashes and restarts. In this paper we model and study the impact of parallelism ...

Packet scheduling over a wireless channel: AQT-based constrained jamming
Fernández Anta, Antonio; Georgiou, Chryssis; Zavou, Elli (2015)In this paper we consider a two-node setting with a sender transmitting packets to a receiver over a wireless channel. Unfortunately, the channel can be jammed, thus corrupting the packet that is being transmitted at the ...
