Going down dangerous paths? (An editorial)

At the end of my 6-year tenure as the Editor-in-Chief of the IEEE/OSA Journal of lightwave technology, I would like to take the opportunity to not only reflect on this very special journal that has served our photonics community for the past 35 years, but more generally on the state ...

Annotate: Organizing Unstructured Contents Via Topic Labels

This is a presentation for the publication that has been already cleared for external release. With the advent of Big Data paradigm, filtering, retrieval, and linking of unstructured multi-modal data has become a necessity. Assigning topic labels to contents, that accurately capture the meaning and contextual information, is a fundamental ...

Deadline Constrained Traffic Handling under Average Power Constraints

Wireless devices need to adapt their transmission power according to the fluctuating wireless channel in order to meet constraints of delay sensitive applications. In this paper, we consider delay sensitivity in the form of strict deadlines on packet arriving in a transmission queue. Packets missing the deadline while in the ...

A Secure End-to-End Cloud Computing Solution for Emergency Management via UAVs

To properly determine the severity of an emergency and provide a quick response, information has to be gathered, confirmed, and analyzed. Artificial intelligence assisted UAV can provide a unique perspective and review extensive information for an incident. However, their limited computing capacity and battery duration raise the challenge to compute-intensive ...

Enabling Dynamic Resource Sharing for Slice Customization in 5G Networks

Network slicing is one of the main novelty of 5G systems and it is expected to radically change the approach of network operators to the support of vertical applications managed by tenants with specific and stringent performance requirements. Static allocation of resources to slices is a straightforward approach to meet ...

On the Impact of Listen-Before-Talk on Ultra-Reliable Low-Latency Communications

In this paper, we study the performance of ultrareliable low latency communication (URLLC) for cellular standalone systems in unlicensed bands. Our focus is on the 5 GHz band, adopting a system model in coherence with the MulteFire standard, which essentially is a variant of LTE (Long Term Evolution) for unlicensed ...

Uplink ultra-reliable low latency communications assessment in unlicensed spectrum

Through this paper, the performance of uplink transmissions in terms of latency and reliability in unlicensed spectrum is addressed. Our goal is to provide insights into how ultra-reliable and low latency communications behave over the unlicensed spectrum in standalone mode. Our system model is based on the MulteFire radio access ...

Throughput Analysis for Relay-Assisted Millimeter-Wave Wireless Networks

In this work, we analyze the throughput of random access multi-user relay-assisted millimeter-wave wireless networks, in which both the destination and the relay have multipacket reception capability. We consider a full-duplex network cooperative relay, which stores the successfully received packets in a queue, whose performance are analyzed. Moreover, we study ...

Performance Analysis of User Plane Connectivity in the 5G Non-Standalone Deployment

The Fifth Generation (5G) radio networks are expected to appear first according to so called non-standalone deployment option, which was created as a set of early specifications by the Third Generation Partnership Project (3GPP). The non-standalone option has its basis in dual-connectivity technique, which allows the use of legacy network ...

Spatial and Temporal Channel Characteristics of 5G 3D Channel Model with Beamforming for User Mobility Investigations

High carrier frequencies are an integral part of the upcoming fifth generation (5G) mobile networks as they offer high data rates and increase the quality of experience. To compensate for the high path loss at high carrier frequencies, beamforming is applied resulting in users connecting and switching between beams of ...

Prototyping Optical Ethernet - A Network for Distributed Data Centers in the Edge Cloud

  • Dembeck L.
  • Gebhard U.
  • Lautenschlaeger W.

Low latency requirements are driving the data center business into the metro area, the so-called Edge Cloud. We investigate the new networking requirements and how they can be served by our Optical Ethernet framework. We elaborate, why the Edge Cloud requires true packet switching in the metro network instead of ...

Making Cable Networks Ready For The Future Through Operations Benchmarking

The current telecommunications business is characterized by fierce competition between Multi System Operators (MSOs) and Communication Service Providers (CSPs) (both called "CSP" in the rest of this paper), flat revenues, and rising network demands and stressing costs. A high percentage of cost is in network OPEX can be attributed to ...

Silicon Photonics: a Scaling Technology for Communications and Interconnects

Silicon photonics exploits CMOS processes to fabricate passive and active photonic circuits on silicon substrates. Its various technical merits implies that this technology can offer superior scalability in terms of integration level and energy efficiency for optical links, two key perspectives to fulfill sustainable capacity growths in future telecom, datacom, ...

We present a new technique allowing the fabrication of large modal count photonic lanterns for space division multiplexing applications. We demonstrate mode-selective photonic lanterns supporting 10 and 15 spatial channels by using graded index fibres and microstructured templates. These templates are a versatile approach to position the graded index fibres ...

Long-haul optical transmission link using low-noise phase-sensitive amplifiers

  • Karlsson M.
  • Olsson S.

The capacity and reach of long-haul fiber optical communication systems is limited by in-line amplifier noise and fiber nonlinearities. Phase-sensitive amplifiers add 6 dB less noise than conventional phase-insensitive amplifiers, such as erbium-doped fiber amplifiers, and they can provide nonlinearity mitigation after each span. Realizing a long-haul transmission link with ...

In the hospitality industry, the room and apartment sharing platform of Airbnb has been accused of unfair competition. Detractors have pointed out the chronic lack of proper legislation. Unfortunately, there is little quantitative evidence about Airbnb?s spatial penetration upon which to base such a legislation. In this study, we analyze ...

Balancing flow table occupancy and link utilization in software-defined networks

Software-Defined Networking (SDN) employs a centralized control with a global network view and provides great opportunities to improve network performance. However, due to the limitation of flow-table space at the switches and unbalanced traffic allocation on links, an SDN may suffer from flow-table overflow and inefficient bandwidth allocation among flows, ...
