The University of Stavanger invites applicants for a Ph.D fellowship in transport layer for 5G Vehicular Edge Computing at the Faculty of Science and Technology, Department of Electrical Engineering and Computer Science. The position is vacant from 01.01.2021.
This is a trainee position that will give promising researchers an opportunity for academic development leading to a doctoral degree.
The appointment is for three years with research duties exclusively, or four years with both research and 25% compulsory duties. This will be clarified in the recruitment process.
Title: Novel Transport Protocols & Services for 5G-enabled Vehicular Edge Computing
Today’s networks and their users are significantly different than those when TCP/IP protocol suite was defined several decades ago. For most of its history TCP and UDP have been the two main transport protocols on the public Internet and they have remained so up until recently. However, today’s networks are much more complex and diverse in design and used technology – e.g., ranging from residential broadband and cellular to IoT, industrial and vehicular networks.
In addition, network applications driven by newly emerging user needs have become far more diverse, and many have more stringent requirements in terms of bandwidth, end-to-end latency and jitter. Such applications are no longer hosted only at the server side but also hosted on the network’s edge using multi-access edge computing (MEC) techniques. It is also becoming more likely that they would be running on a virtualized or containerized platform instead of bare metal. Even the network management and functionalities are moving towards becoming more virtualized using SDN and NFV techniques, particularly in upcoming 5G networks.
A rapidly evolving field in networking is the vehicular communication, where cooperative, connected and automated mobility (CCAM) in the context of cooperative intelligent transport systems (C-ITS) is enabled by the means of vehicle-to-everything (V2X) communication. V2X involves the communication among vehicles, road users, road infrastructure and the cloud-based backend and it can use a wide range of available technologies, most notably cellular LTE and 802.11p-based DSRC. V2X can potentially offer a wide range of services to the end-user from automated and connected driving, and safety critical services to infotainment and augmented/virtual reality (AR/VR).
Due to its mobile and potentially safety-critical nature, vehicular applications require ultra-reliable and low-latency communication (URLLC) – e.g., in order of ~1ms – a service category that is also envisioned in upcoming 5G V2X initially defined in 3GPP Release 14. One of the challenges of ensuring URLLC lay in the transport layer stack, where TCP is known to perform sup-optimally particularly in the wireless environments. An increasingly popular transport protocol known as QUIC – initially developed by Google and being standardized at the IETF – have tried to mitigate this poor performance but have not been thoroughly evaluated in V2X scenarios. In addition, novel transport protocols and mechanisms may need to be devised that suit the V2X scenarios better. Such protocols should take into consideration the requirements of virtualized and vehicular MEC (VEC) environments.
The successful candidate will undertake the design and development of novel transport protocol and services for V2X communication by considering a variety of underlying network technologies with a particular focus on 5G V2X, C-ITS scenarios (e.g., road and tunnel safety), and network environments (virtualization, containerization and VEC). This will inherently involve the following:
- Vehicular Emulator Testbed: developing a testbed emulating the vehicular environment. Among other things, this may leverage the use of 5G/LTE D2D communication using PC5 (sidelink) interface with SDR.
- VEC server: design and development of VEC platforms for hosting vehicular applications (e.g., road/tunnel safety C-ITS services) using latest NFV, SDN and virtualization/containerization techniques. This will also involve the development of several candid C-ITS applications that can be offered by the VEC server.
- Transport: design, development and real-life evaluation of transport layer protocols suitable for virtualized VEC environments and V2X communication. This will also investigate the use of Active Queue Management (ACM) and Explicit Congestion Notification (ECN) in vehicular environments. The evaluations in this phase will be performed using vehicular emulator testbed and VEC server. This activity will also investigate the performance of QUIC and HTTP/3 in vehicular environments.
We are looking for applicants with a strong academic background who have completed a five-year master degree (3+2) within Communication Technology, preferably acquired recently; or possess corresponding qualifications that could provide a basis for successfully completing a doctorate.
To be eligible for admission to the doctoral programmes at the University of Stavanger both the grade for your master’s thesis and the weighted average grade of your master’s degree must individually be equivalent to or better than a B grade.
Applicants with an education from an institution with a different grade scale than A-F should attach a confirmed conversion scale that shows how the grades can be compared with the Norwegian A-F scale.
Excellent knowledge of communication networking and research experience on Internet transport layer or vehicular networks is required (e.g., related Master thesis or articles).
Experience with real-life testing and evaluation of networks (e.g., 4G LTE or other wireless networks), automated network experimentation, and familiarity with MEC/VEC and SDN/NFV concepts and techniques are highly desired.
In addition, familiarity with 3GPP, ETSI and IETF standards is a plus.
Emphasis is also placed on your:
- motivation and potential for research within the field
- your professional and personal skills for completing the doctoral degree within the timeframe
- ability to work independently and in a team, be innovative and creative
- ability to work structured and handle a heavy workload
- having a good command of both oral and written English
