Virtualizing Heterogeneous Wireless Networks with SDN for the 5G
We are looking for students who are enthusiastic about new communication technologies and motivated for addressing some fundamental problems related to our Internet (of things).
Network operators have started to aim at providing a connectivity to the Internet of Things: in smart cities, small devices such as smart meters have to push their data unfrequently to the Internet. A myriad of different technologies has begun to emerge on the market, along with a variety of scenarios, and using the same unlicensed band. The PhD student will explore how to exploit all these technologies with a virtualized architecture: he or she will propose new mechanisms to introduce cooperation among them, to provide end-to-end guarantees.
The university of Strasbourg is a top-level French University. This PhD position is part of the IdEx program of the University of Strasbourg, which provides specific conditions to the PhD student
While the historical mobile networks were primarily designed for voice and later extended for data communication (smartphones), we now face the rise of more intensive Machine-To-Machine communications. The LTE technology has recently provided a way to increase the throughput (≈300Mbps), but it is mainly dedicated to smartphone applications. In particular, such technology has not been designed to support a very large density of devices transmitting only a few data packets per day / week. The 5G networks provide a cornerstone architecture for enabling the emerging smart cities and smart buildings applications that exhibit those characteristics.
Currently, we face concurrent technologies for the Internet of Things (LoRA, IEEE 802.11ah, IEEE 802.15.4g, IEEE 8021.5.4e-TSCH) which all exploit the same unlicensed band. Each of these technologies has its own advantages and scenario of predilection: they will probably have to cohabit in the future. One of the major future challenges will consist in exploiting a symbiosis between multiple of them.
The PhD student will explore how we may use all these technologies to provide connectivity in the Internet of Everything. First of all, he or she will conduct experiments on our FIT IoT-Lab (http://iot-lab.info/) platform to more accurately model their interactions, and to extract pathological situations.
The second step will consist of proposing a new architecture, and new mechanisms to make them work together. We must be able to provide mechanisms to guarantee end-to-end performance: whatever the technology used for each hop, a minimum reliability or a maximum delay should be secured. Software Defined Networking (SDN) may provide interesting mechanisms to guarantee flow isolation.
