The usage of mobile phones is growing rapidly thereby increasing the traffic in mobile networks. New radio technologies such as LTE-A are evolving, promising large bit rates, but in order to support the traffic growth the communication infrastructure interconnecting all the mobile base stations must be considered. Bottlenecks in this backhaul network can severely impact the applications running on the mobile devices. On the other hand the backhaul network is costly to build and operate and therefore it should be designed to operate efficiently with the available resources to also keep energy consumption reasonable. This could also be impacted by the protocols controlling the traffic flow in the network. As it is today, TCP controls the majority of the Internet traffic although it was designed for networks very different from modern mobile networks.
The objective of the project is to investigate new architectures for mobile backhaul keeping in mind the energy consumption and mobile application performance. One starting point could be Cloud-RAN based architectures to share resources between base stations. Furthermore, new protocols (a “mobile TCP”) Providing QoS and energy efficiency in mobile networks should be investigated and designed using e.g., computer simulation.
Qualifications: Candidates should have a Master’s Degree in Engineering or a similar degree with an academic level equivalent to the master’s degree in engineering. Candidates with experience in mobile communication, network architectures and network analysis and design based on computer based protocols simulations are encouraged to apply. Moreover the candidate shall have additional skills as:
- Ability to work independently, to plan and carry out complicated tasks
- Ability to combine many areas and see the full picture
- Good communication skills in English, both written and spoken
Approval and Enrolment: The scholarships for the PhD degree are subject to academic approval, and the candidates will be enrolled in one of the General Degree Programmes of DTU.
