An energy-efficient NOMA for small cells in heterogeneous CRAN

Vien, Q.-T., Le, T. A., Phan, C. V. and Opoku Agyeman, M. (2017) An energy-efficient NOMA for small cells in heterogeneous CRAN under QoS constraints. Paper to be presented to: 23rd European Wireless (EW), Dresden, Germany, 17-19 May 2017

Abstract

This paper investigates downlink performance of wireless backhaul in a heterogeneous cloud radio access net- work (HCRAN) consisting of a cloud-based central station (CCS) and multi-tier small cells. Non-orthogonal multiple access (NOMA) is adopted for the downlink from the CCS to multiple small cells of different types (e.g. microcells, picocells and femtocells). Taking into account practical power consumption at small cells operating within various propagation environment models, we first develop a power allocation for the NOMA, which allows us to derive the energy efficiency (EE) of the wireless backhaul in the practical HCRAN downlink. It is shown that the NOMA is superior to the conventional OFDMA scheme achieving a higher EE of up to six times with the deployment of small cells. The propagation environment is also shown to have a significant impact on the EE performance with a big gap between different cell types when the number of cells is large. Particularly, the EE of the NOMA is shown to not always increase or decrease as a function of the number of cells, while the throughput performance at the cloud edge is strikingly degraded as the number of cells increases. This accordingly motivates us to propose a two-stage algorithm for determining the optimal number of various cells that maximises the EE of the HCRAN while still maintaining the QoS requirement at the cloud edge. Simulation results show that, to meet a target cloud-edge throughput, the same number of femtocells and picocells can be used; however, the femtocells are favourable to the picocells in achieving the maximal EE.

BCS event - Advanced Penetration Testing Bootcamp

BCS Northampton Branch & University of Northampton

BCS Young Professionals Information Security Group

present

Advanced Penetration Testing Bootcamp (201)

Do you think you have the skills to work as a white hat hacker? Does the idea of penetration testing applications and infrastructure and learning the techniques for breaking into systems seem to be your ideal career?

If you are a student in IT or you have experience as IT or Security professional, and maybe already know the difference between Nmap, MetaSploit and Burp, then this could be the event for you!

Date:	Saturday 22nd April 2017
Time:	Registration, Setup, Introductions - 09:00 Event Start 10:00 - End 17:00 approx.
Venue:	University of Northampton http://bit.ly/2oAP0ha
Sign-up:	https://events.bcs.org/book/2538/

A one day advanced penetration testing bootcamp, starting with how to develop a career in penetration testing, reviewing the methodology involved and getting close up with the tools used by professional ethical hackers. The event has hands-on sessions with theory and labs.

Please note this opportunity is only open to a maximum of 40 attendees early booking is advised.

Since this course is advanced due to the technical topics and tools covered, to leverage full value and be able to keep up with the pace during the day,  strongly recommend and invite those who have previous experience within IT Security, ethical hacking and/or have prior experience of working with Linux, web applications, databases, and network protocols to register early.
