Goal-oriented Policies for Cost of Actuation Error Minimization in Wireless Autonomous Systems
Emmanouil Fountoulakis, Nikolaos Pappas, Marios Kountouris
We consider the minimization of the cost of actuation error under resource constraints for real-time tracking in wireless autonomous systems. A transmitter monitors the state of a…
Scheduling Policies for AoI Minimization with Timely Throughput Constraints
Emmanouil Fountoulakis, Themistoklis Charalambous, Anthony Ephremides +1
In 5G and beyond communication systems, the notion of latency gets great momentum in wireless connectivity as a metric for serving real-time communications requirements. However, i…
Joint Sampling and Transmission Policies for Minimizing Cost under AoI Constraints
Emmanouil Fountoulakis, Marian Codreanu, Anthony Ephremides +1
In this work, we consider the problem of jointly minimizing the average cost of sampling and transmitting status updates by users over a wireless channel subject to average Age of…
Dynamic Power Control for Time-Critical Networking with Heterogeneous Traffic
Emmanouil Fountoulakis, Nikolaos Pappas, Anthony Ephremides
Future wireless networks will be characterized by heterogeneous traffic requirements. Such requirements can be low-latency or minimum-throughput. Therefore, the network has to adju…
Information Freshness and Packet Drop Rate Interplay in a Two-User Multi-Access Channel
Emmanouil Fountoulakis, Themistoklis Charalambous, Nikolaos Nomikos +2
In this work, we combine the two notions of timely delivery of information in order to study their interplay; namely, deadline-constrained packet delivery due to latency constraint…
Optimal Sampling Cost in Wireless Networks with Age of Information Constraints
Emmanouil Fountoulakis, Nikolaos Pappas, Marian Codreanu +1
We consider the problem of minimizing the time average cost of sampling and transmitting status updates by users over a wireless channel subject to average Age of Information const…
UAV Trajectory Optimization for Time Constrained Applications
Emmanouil Fountoulakis, Georgios S. Paschos, Nikolaos Pappas
Unmanned Aerial Vehicles (UAVs) are poised to revolutionize communications. Utilizing their flexibility and fast deployment, we can deliver content in congested areas or provide se…
An End-to-End Performance Analysis for Service Chaining in a Virtualized Network
Emmanouil Fountoulakis, Qi Liao, Nikolaos Pappas
Future mobile networks supporting Internet of Things are expected to provide both high throughput and low latency to user-specific services. One way to overcome this challenge is t…
Traversing Virtual Network Functions from the Edge to the Core: An End-to-End Performance Analysis
Emmanouil Fountoulakis, Qi Liao, Manuel Stein +1
Future mobile networks supporting Internet of Things are expected to provide both high throughput and low latency to user-specific services. One way to overcome this challenge is t…
Dynamic Power Control for Packets with Deadlines
Emmanouil Fountoulakis, Nikolaos Pappas, Qi Liao +2
Wireless devices need to adapt their transmission power according to the fluctuating wireless channel in order to meet constraints of delay sensitive applications. In this paper, w…
An Examination of the Benefits of Scalable TTI for Heterogeneous Traffic Management in 5G Networks
Emmanouil Fountoulakis, Nikolaos Pappas, Qi Liao +2
The rapid growth in the number and variety of connected devices requires 5G wireless systems to cope with a very heterogeneous traffic mix. As a consequence, the use of a fixed TTI…
