Video Quality Monitoring for Remote Autonomous Vehicle Control
Dimitrios Kafetzis, Nikos Fotiou, Savvas Argyropoulos +2
The delivery of high-quality, low-latency video streams is critical for remote autonomous vehicle control, where operators must intervene in real time. However, reliable video deli…
Blind Optimal User Association in Small-Cell Networks
Livia Elena Chatzieleftheriou, Apostolos Destounis, Georgios Paschos +1
We learn optimal user association policies for traffic from different locations to Access Points(APs), in the presence of unknown dynamic traffic demand. We aim at minimizing a bro…
Community Networks and Sustainability: a Survey of Perceptions, Practices, and Proposed Solutions
Panagiota Micholia, Merkouris Karaliopoulos, Iordanis Koutsopoulos +5
Community network (CN) initiatives have been around for roughly two decades, evangelizing a distinctly different paradigm for building, maintaining, and sharing network infrastruct…
Streaming Big Data meets Backpressure in Distributed Network Computation
Apostolos Destounis, Georgios S. Paschos, Iordanis Koutsopoulos
We study network response to queries that require computation of remotely located data and seek to characterize the performance limits in terms of maximum sustainable query rate th…
Evolution of IEEE 802.11 compatible standards and impact on Energy Consumption
Stratos Keranidis, Giannis Kazdaridis, Nikos Makris +3
Over the last decade, the IEEE 802.11 has emerged as the most popular protocol in the wireless domain. Since the release of the first standard version, several amendments have been…
Optimal Primary-Secondary user Cooperation Policies in Cognitive Radio Networks
Nestor Chatzidiamantis, Evangelia Matskani, Leonidas Georgiadis +2
In cognitive radio networks, secondary users (SUs) may cooperate with the primary user (PU), so that the success probability of PU transmissions are improved, while SUs obtain more…
Incentive Mechanisms for Hierarchical Spectrum Markets
George Iosifidis, Anil Kumar Chorppath, Tansu Alpcan +1
In this paper, we study spectrum allocation mechanisms in hierarchical multi-layer markets which are expected to proliferate in the near future based on the current spectrum policy…
Competition and Regulation in Wireless Services Markets
Omer Korcak, George Iosifidis, Tansu Alpcan +1
We consider a wireless services market where a set of operators compete for a large common pool of users. The latter have a reservation utility of U0 units or, equivalently, an alt…
Control and Optimization Meet the Smart Power Grid - Scheduling of Power Demands for Optimal Energy Management
Iordanis Koutsopoulos, Leandros Tassiulas
The smart power grid aims at harnessing information and communication technologies to enhance reliability and enforce sensible use of energy. Its realization is geared by the funda…
