Estimation of the last passage percolation constant in a charged complete directed acyclic graph via perfect simulation
Sergey Foss, Takis Konstantopoulos, Bastien Mallein +1
Our object of study is the asymptotic growth of heaviest paths in a charged (weighted with signed weights) complete directed acyclic graph. Edge charges are i.i.d. random variables…
Age of Information for Small Buffer Systems
George Kesidis, Takis Konstantopoulos, Michael Zazanis
Consider a message processing system whose objective is to produce the most current information as measured by the quantity known as "age of information". We have argued in previou…
Age of information distribution under dynamic service preemption
George Kesidis, Takis Konstantopoulos, Michael A. Zazanis
Age of Information (AoI) has emerged as an important quality-of-service measure for applications that prioritize delivery of the freshest information, e.g., virtual or augmented re…
Age of information without service preemption
George Kesidis, Takis Konstantopoulos, Michael A. Zazanis
When designing a message transmission system, from the point of view of making sure that the information transmitted is as fresh as possible, two rules of thumb seem reasonable: us…
