  • Hao F.
  • Lakshman T.
  • Montgomery D.
  • Sriram K.

While being critical to the network management, the current state of the art in network measurement is inadequate, providing surprisingly little visibility into detailed network behaviors and often requiring high level of manual intervention to operate. Such a practice becomes increasingly ineffective as the networks grow both in size and ...

Vectoring-Based Dynamic Spectrum Management for G.fast Multi-User Full-Duplex Transmission

  • Lanneer W.
  • Maes J.
  • Moonen M.
  • Tsiaflakis P.

Full-duplex transmission is a new challenging technique emerging in DSL networks that may double the spectral efficiency by transmitting in the downstream (DS) and upstream (US) at the same time on identical frequencies. Unfortunately, this leads to severe near-end crosstalk (NEXT) interference in addition to the conventional far-end crosstalk (FEXT) ...

STAR: Preventing flow-table overflow in software-defined networks

  • Liu R.
  • Walid A.
  • Xu Y.

The emerging Software-Defined Networking (SDN) enables network innovation and flexible control for network operations. A key component of SDN is the flow table at each switch, which stores flow entries that define how to process the received flows. In a network that has a large number of active flows, flow ...

  • Cavalcante R.
  • Liao Q.

We propose novel resource allocation algorithms that have the objective of finding a good tradeoff between resource reuse and interference avoidance in wireless networks. To this end, we first study properties of functions that relate the resource budget available to network elements to the optimal utility and to the optimal ...

  • Peter Danielsen
  • Pianese F.

An automated offline design process for optimized cross-layer schedulers can produce augmented scheduling algorithms tailored to a target deployment scenario. We discuss the application of ODDS, a reinforcement learning technique we introduced, for augmenting LTE MAC scheduler algorithms of practical significance. ODDS observes the correlation between the value of a ...

Motivated by scenario requirements for 5G cellular networks, we study one among the protocols candidate to the massive random access: the family of random access methods known as Coded Slotted ALOHA (CSA). Recent body of research has explored aspects of such methods in various contexts, but one aspect has not ...

On-off necklace codes for asynchronous mutual discovery

We consider mutual discovery of asynchronous wireless transceivers with a fixed activity ratio. On-off activity patterns are slotted, and repeat in discovery frames. For discovery it has to be guaranteed that the activity patterns of two transceivers are not overlapping. We design necklace codes determining activity patterns to guarantee discovery ...

Delay Comparison of Delivery and Coding Policies in Data Clusters

  • Baccelli F.
  • Bouillard A.
  • Shah V.

A key function of cloud infrastructure is to store and deliver diverse files, e.g., scientific datasets, social network information, videos, etc. In such systems, for the purpose of fast and reliable delivery, files are divided into chunks, replicated or erasure-coded, and disseminated across servers. It is neither known in general ...

Random-access algorithms such as the CSMA protocol provide a popular mechanism for distributed medium access control in large-scale wireless networks. Mean-field analysis has emerged as a convenient approach to obtain tractable performance estimates in such networks, but a critical limitation of the classical set-up is that all nodes are assumed ...

  • Jalali S.
  • Poor H.
  • Rezagah F.

Modern compression codes exploit signals’ complex structures to encode them very efficiently. On the other hand, compressed sensing algorithms recover “structured” signals from their under-determined set of linear measurements. Currently, there is a noticeable gap between the types of structures used in the area of compressed sensing and those employed ...

  • Cello M.
  • Gnecco G.
  • Marchese M.
  • Patrone F.
  • Sanguineti M.

Network congestion is a well-known problem that may heavily affect the overall network performance. Congestion control approaches in Intermittently-Connected Networks (ICNs) differ from those used in classical networks, since the assumptions of ``universal connectivity{''} of the nodes and ``global information{''} about the network do not hold. In this paper, an ...
