Local Voting: A New Distributed Bandwidth Reservation Algorithm for 6TiSCH Networks
Dimitrios J. Vergados, Katina Kralevska, Yuming Jiang +1
The IETF 6TiSCH working group fosters the adaptation of IPv6-based protocols into Internet of Things by introducing the 6TiSCH Operation Sublayer (6top). The 6TiSCH architecture in…
Evaluation of HTTP/DASH Adaptation Algorithms on Vehicular Networks
Dimitrios J. Vergados, Angelos Michalas, Katina Kralevska +1
Video streaming currently accounts for the majority of Internet traffic. One factor that enables video streaming is HTTP Adaptive Streaming (HAS), that allows the users to stream v…
All-Optical FSO Relaying Under Mixture-Gamma Fading Channels and Pointing Errors
Nikolaos I. Miridakis, Dimitrios D. Vergados, Angelos Michalas
The performance of all-optical dual-hop relayed free-space optical communication systems is analytically studied and evaluated. We consider the case when the total received signal…
All Cognitive MIMO: A New Multiuser Detection Approach with Different Priorities
Nikolaos I. Miridakis, Theodoros A. Tsiftsis, Dimitrios D. Vergados +1
A new detection scheme for multiuser multiple-input multiple-output (MIMO) systems is analytically presented. In particular, the transmitting users are being categorized in two dis…
