Exact Analytical Model of Age of Information in Multi-source Status Update Systems with Per-source Queueing
Ege Orkun Gamgam, Nail Akar
We consider an information update system consisting of sources sending status packets at random instances according to a Poisson process to a remote monitor through a single se…
Scheduling Algorithms for Age of Information Differentiation with Random Arrivals
Nail Akar, Ezhan Karasan
We study age-agnostic scheduling in a non-preemptive status update system with two sources sending time-stamped information packets at random instances to a common monitor through…
The Multi-Source Preemptive M/PH/1/1 Queue with Packet Errors: Exact Distribution of the Age of Information and Its Peak
Ozancan Dogan, Nail Akar
Age of Information (AoI) and Peak AoI (PAoI) and their analytical models have recently drawn substantial amount of attention in information theory and wireless communications disci…
Discrete-time Queueing Model of Age of Information with Multiple Information Sources
Nail Akar, Ozancan Dogan
Information freshness in IoT-based status update systems has recently been studied through the Age of Information (AoI) and Peak AoI (PAoI) performance metrics. In this paper, we s…
The MAP/M/s+G Call Center Model with General Patience Times: Stationary Solutions and First Passage Times
Omer Gursoy, Kamal Adli Mehr, Nail Akar
We study the MAP/M/s+G queuing model with MAP (Markovian Arrival Process) arrivals, exponentially distributed service times, infinite waiting room, and generally distributed patien…
Finding the Exact Distribution of (Peak) Age of Information for Queues of PH/PH/1/1 and M/PH/1/2 Type
Nail Akar, Ozancan Dogan, Eray Unsal Atay
Bufferless and single-buffer queueing systems have recently been shown to be effective in coping with escalated Age of Information (AoI) figures arising in single-source status upd…
Joint Cell Muting and User Scheduling in Multi-Cell Networks with Temporal Fairness
Shahram Shahsavari, Nail Akar, Babak Hossein Khalaj
A semi-centralized joint cell muting and user scheduling scheme for interference coordination in a multicell network is proposed under two different temporal fairness criteria. The…
