Interledger Smart Contracts for Decentralized Authorization to Constrained Things
Vasilios A. Siris, Dimitrios Dimopoulos, Nikos Fotiou +2
We present models that utilize smart contracts and interledger mechanisms to provide decentralized authorization for constrained IoT devices. The models involve different tradeoffs…
ICN enabling CoAP Extensions for IP based IoT devices
Nikos Fotiou, George Xylomenos, George C. Polyzos +4
The Constrained Application Protocol (CoAP) and its extensions, such as observe and group communication, offer the potential for developing novel IoT applications. However, a full-…
Multi-Flow Congestion Control with Network Assistance
Yannis Thomas, George Xylomenos, Christos Tsilopoulos +1
A well-known technique for enhancing the performance and stability of content distribution is the use of multiple dissemination flows. Multipath TCP (MPTCP), the most popular multi…
Securing Information-Centric Networking without negating Middleboxes
Nikos Fotiou, George Xylomenos, George C. Polyzos
Information-Centric Networking is a promising networking paradigm that overcomes many of the limitations of current networking architectures. Various research efforts investigate s…
Object-oriented Packet Caching for ICN
Yannis Thomas, George Xylomenos, Christos Tsilopoulos +1
One of the most discussed features offered by Information-centric Networking (ICN) architectures is the ability to support packet-level caching at every node in the network. By ind…
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…
Efficient Proactive Caching for Supporting Seamless Mobility
Vasilios A. Siris, Xenofon Vasilakos, George C. Polyzos
We present a distributed proactive caching approach that exploits user mobility information to decide where to proactively cache data to support seamless mobility, while efficientl…
From advertising profits to bandwidth prices-A quantitative methodology for negotiating premium peering
Laszlo Gyarmati, Nikolaos Laoutaris, Kostas Sdrolias +2
We have developed a first of its kind methodology for deriving bandwidth prices for premium direct peering between Access ISPs (A-ISPs) and Content and Service Providers (CSPs) tha…
Packet Travel Times in Wireless Relay Chains under Spatially and Temporally Dependent Interference
Alessandro Crismani, Udo Schilcher, Stavros Toumpis +2
We investigate the statistics of the number of time slots that it takes a packet to travel through a chain of wireless relays. Derivations are performed assuming an interferenc…
Improving Mobile Video Streaming with Mobility Prediction and Prefetching in Integrated Cellular-WiFi Networks
Vasilios A. Siris, Maria Anagnostopoulou, Dimitris Dimopoulos
We present and evaluate a procedure that utilizes mobility and throughput prediction to prefetch video streaming data in integrated cellular and WiFi networks. The effective integr…
On the Performance of Network Coding and Forwarding Schemes with Different Degrees of Redundancy for Wireless Mesh Networks
Manolis Ploumidis, Nikolaos Pappas, Vasilios A. Siris +1
This study explores the throughput and delay that can be achieved by various forwarding schemes employing multiple paths and different degrees of redundancy focusing on linear netw…
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…
Performance and Energy Efficiency of Mobile Data Offloading with Mobility Prediction and Prefetching
Vasilios A. Siris, Maria Anagnostopoulou
We present a detailed evaluation of procedures that exploit mobility prediction and prefetching to enhance offloading of traffic from mobile networks to WiFi hotspots, for both del…
Enhancing Mobile Data Offloading with Mobility Prediction and Prefetching
Vasilios A. Siris, Dimitrios Kalyvas
We present procedures that exploit mobility prediction and prefetching to enhance offloading of traffic from mobile networks to WiFi hotspots, for both delay tolerant and delay sen…
