Optimisation of wireless networks for efficient real-time audio/media networking

Primary Supervisor: Dr Christos Chousidis

Research context

Audio networking is an increasing field, which introduces new exciting possibilities for the professional audio industry and is expected to drastically change the way audio systems will be designed, built and used in the future. Today’s networks provide enough bandwidth to transport hundreds of high-quality audio channels, replacing complex and expensive conventional audio infrastructures. Currently, there are many systems on the market that distribute audio over Ethernet lacking, however, popularity within the audio engineering industry. This is because most of these systems are based on a proprietary implementation and also, like conventional analogue audio implementations, require a cable infrastructure. In this research, the development of a wireless interoperable digital audio networking system will be investigated

Research goal

The main goal of this research is to develop a wireless interoperable digital audio networking system, based on IEEE 802.11 (Wi-Fi) wireless technology. A series of modifications in the Medium Access Control algorithm of the standard will be proposed and tested in order to improve performance in a multi-channel audio networking environment. This PhD research will focus on the modification of the IEEE 802.11 MAC algorithm in order to achieve a reliable congestion control on a multi-broadcasting environment of real-time audio data.

Candidate profile

Applicants will be expected to hold a good first degree (first or upper second class) and a Masters degree (or significant industrial experience) in Computing, Data Communications and Networks or Electronic Engineering.  The candidate should be able to work independently and in a collaborative environment and be able to contact applied research work with minimum supervision. The candidate should have excellent programming skills in C++ and be familiar with Linux environment. In addition, he/she should have experience in MATLAB, network simulation and prototyping. A background in audio systems or music technology will be desirable but not essential for this role.
