  • Mai T.
  • Sala A.

Understanding user behavior is essential to personalize and enrich a user's online experience. While there are significant benefits to be accrued from the pursuit of personalized services based on a fine-grained behavioral analysis, care must be taken to address user privacy concerns. In this paper, we consider the use of ...

The fifth generation (5G) of communication systems will need to support new applications with a variety of requirements, such as high data rates, low latency, enhanced indoor coverage and a large number of devices. It is strongly believed that the expected demands can be satisfied by combining the usage of ...

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

  • Satzke K.

ICN promises benefits to users and service providers along several dimensions, including lower response time, nearest-replica routing, intrinsic content integrity without external network-level indicators, location-independent naming and improved support for mobility. Unfortunately these benefits come at a non-trivial cost as many ICN proposals call for adding significant complexity to the ...

Nonlinear Capacity Limit to Optical Communications

  • Essiambre R.

An introduction to the measure of information of a signal is presented. Challenges specific to calculating a nonlinear Shannon fiber capacity are highlighted.

Field insights: Small cells in large enterprises

Optimizing Enterprise Cloud Applications on Data-Insights

  • Sala A.

The Cloud has become a compelling infrastructure to host a number of diverse services and applications with different operational and service requirements. New trends are showing an increasingly complex landscape comprised of a wide variety of applications ranging from mission critical services, such as network control functions, to time-critical functions ...

CO-OFDM for optical slot switching in datacenters

  • Bigo S.
  • Estaran Tolosa J.
  • Jenneve P.
  • Mardoyan H.
  • Mestre Adrover M.

We demonstrate for the first time the application of RF-pilot aided CO-OFDM modulation in optical slot switching-based datacenter networks. Low complexity CO-OFDM outperforms Single-carrier transmission in terms of node cascadability when using low-cost 100 GHz AWGs

Inferring Networked Device Categories from Low-Level Activity Indicators

  • Chandrashekar J.
  • Christophedes V.
  • Sheykh Esmaili K.

We study the problem of inferring the category of a networked device based on observed, low level indicators of its activity (traffic counters and wireless signal strengths). Such a capability has a wide variety of uses including ISP home troubleshooting, traffic management, etc. In this paper, we analyze a dataset ...

Impact of Receiver Optical Filter Bandwidth and Shape on the Performance of Burst-mode Upstream with DML

  • Bernhard Deppisch
  • Bonk R.
  • Pfeiffer T.
  • Poehlmann W.

DMLs under burst-mode suffer from drift of optical frequency, which tunes the transmitter out of the receiver filter. We compare the receiver sensitivity spread and find that a flat-top filter of 50GHz grid has similar performance as 100GHz Gaussian shaped.

Performance Impact of LoS and NLoS Transmissions in Small Cell Networks

  • Guoqiang Mao
  • Lopez-Perez D.
  • Ming Ding
  • Peng Wang
  • Zihuai Lin

In this paper, we introduce a sophisticated path loss model incorporating both line-of-sight (LoS) and non-line-of-sight (NLoS) transmissions to study their performance impact in small cell networks (SCNs). Analytical results are obtained on the coverage probability and the area spectral efficiency (ASE) for two user association strategies (UASs) assuming both ...
