Statistical Age-of-Information Bounds for Parallel Systems: When Do Independent Channels Make a Difference?
Markus Fidler, Jaya Champati, Joerg Widmer +1
This paper contributes tail bounds of the age-of-information of a general class of parallel systems and explores their potential. Parallel systems arise in relevant cases, such as…
Age- and Deviation-of-Information of Time-Triggered and Event-Triggered Systems
Mahsa Noroozi, Markus Fidler
Age-of-information is a metric that quantifies the freshness of information obtained by sampling a remote sensor. In signal-agnostic sampling, sensor updates are triggered at certa…
A Min-plus Model of Age-of-Information with Worst-case and Statistical Bounds
Mahsa Noroozi, Markus Fidler
We consider networked sources that generate update messages with a defined rate and we investigate the age of that information at the receiver. Typical applications are in cyber-ph…
Non-Asymptotic Delay Bounds for Multi-Server Systems with Synchronization Constraints
Markus Fidler, Brenton Walker, Yuming Jiang
Multi-server systems have received increasing attention with important implementations such as Google MapReduce, Hadoop, and Spark. Common to these systems are a fork operation, wh…
A Benchmark for the Performance of Time-varying Closed-loop Flow Control with Application to TCP
Ralf Lübben, Markus Fidler
Closed-loop flow control protocols, such as the prominent implementation TCP, are prevalent in the Internet, today. TCP has continuously been improved for greedy traffic sources to…
A Non-stationary Service Curve Model for Estimation of Cellular Sleep Scheduling
Nico Becker, Markus Fidler
While steady-state solutions of backlog and delay have been derived for essential wireless systems, the analysis of transient phases still poses significant challenges. Considering…
