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

  • Chao H.
  • Guo Z.
  • Gushchin A.
  • 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 ...

Improving resource efficiency with partial resource muting for future wireless networks

  • 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 ...

Augmenting Practical Cross-layer MAC Schedulers via Offline Reinforcement Learning

  • 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 ...

Near Far Effect on Coded Slotted Aloha

  • Alloum A.
  • Cedric Adjih
  • Ehsan Ebrahimi Khaleghi
  • Paul Muhlethaler

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 ...

Dynamic IP Tunneling for Next Generation Mobile Networks

  • Calin D.
  • Kim B.
  • Ling J.
  • Viswanathan H.

The paper describes the principles of a novel mechanism that is aiming at providing unprecedented Quality of Experience (QoE) in next generation mobile networks. The main benefits include: (i) enabling dynamic IP tunnel management (establishing and tearing down) with terminating point in the mobile device instead of the traditional base ...

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 ...

Beyond the next 700 lot platforms

The emergence of the Internet of Things (IoT) brings us connected devices that are an integral part of the physical world. Everyday devices and things will have considerable computing and communication capabilities, and will turn the real world programmable in a very literal sense. The dawn of the Programmable World ...

Evolution of Social Power for Opinion Dynamics Networks

  • Iglesias Rey S.
  • Silva A.
  • Valenzuela P.

This paper studies the evolution of interpersonal influences in a group as they discuss a sequence of issues following a particular opinion dynamics model. In this work, we propose a general opinion dynamics model and we extend it to the evolution of influence networks using the model of reflected appraisal ...

Spatial mean-field limits for CSMA networks

  • Borst S.
  • Cecchi F.
  • Van Leeuwaarden J.
  • Whiting P.

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 ...

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 ...

Coded fourier transform

  • Avestimehr A.
  • Maddah-Ali M.
  • Yu Q.

We consider the problem of computing the Fourier transform of high-dimensional vectors, distributedly over a cluster of machines consisting of a master node and multiple worker nodes, where the worker nodes can only store and process a fraction of the inputs. We show that by exploiting the algebraic structure of ...

  • Jonathan Rodriguez
  • Kazi Mohammed Saidul Huq

The ever-increasing demand for data traffic for future wireless systems poses challenging requirements for 5G wireless communications, such as high spectral efficiency, better interference management, and extensive connectivity. These challenges open the possibility to use non-orthogonal multiple access (NOMA) schemes in future radio access networks. In these schemes, the users ...

A theoretical analysis of buffer occupancy for Intermittently-Connected Networks

  • Boero L.
  • 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 ...
