Network-based dynamic prioritization of HTTP adaptive streams to avoid video freezes

  • Bostoen T.
  • De Turck F.
  • Huysegems R.
  • Petrangeli S.
  • Wauters T.

HTTP Adaptive Streaming (HAS) is becoming the de-facto standard for video streaming services over the Internet. In HAS, each video is segmented and stored in different qualities. Rate adaptation heuristics, deployed at the client, allow the most appropriate quality level to be dynamically requested, based on the current network conditions. ...

Fair comparison of the contentionless property in OXC

Compressive Sensing via Low-Rank Gaussian Mixture Models

  • Huang G.
  • Jiang H.
  • Wilford P.
  • Yuan X.

We develop a new compressive sensing (CS) inversion algorithm by utilizing the Gaussian mixture model (GMM). While the compressive sensing is performed globally on the entire image as implemented in our lensless camera, a low-rank GMM is imposed on the local image patches. This low-rank GMM is derived via eigenvalue ...

Channel Estimation and Precoding in Closed-Loop Distributed Multi-Antenna Systems

  • Wild T.

Today's wireless cellular systems are limited by inter-cell interference. Coordinated multi-point transmission and reception (CoMP) is a promising approach to cope with this problem. Here, multiple base stations act as a distributed antenna system, exchanging coordination information and potentially user data via backhaul in order to reduce this interference, increasing ...

Public Verifiability in the Covert Model (Almost) for Free

  • Kolesnikov V.
  • Malozemoff A.

Abstract. The covert security model (Aumann and Lindell, TCC 2007) offers an extremely important security/efficiency trade-off: a covert player may arbitrarily cheat, but will be caught with a certain fixed probability, called the deterrence factor. This permits much more efficient protocols than the malicious setting while still giving meaningful security ...

LTE deployment options: Make the best choice

  • Urie A.

LTE deployment using a network overlay for rapid wide area deployment is a more efficient approach than adding LTE support as part of an overall cell site upgrade using single radio access network (RAN). In this article, I will review both options and share projected implementation data that supports choosing ...

When Base Stations Meet Mobile Terminals, and Some Results Beyond

  • Fettweis G.
  • Suryaprakash V.

Wireless networks are designed based on population patterns. To densify networks, the organization of a cellular network is, therefore, done according to user density to minimize the cost of investment. Since populations do not appear in the form of a regular geometric grid, the planning of networks should not either. ...

DNS Modifications for Real-World ICN Benefits
