Two PhD Research Fellows - Signal Processing and Artificial Intelligence for wireless networks
The University of Agder (UiA), Faculty of Engineering and Science, Department of Information and Communication Technology, invites applications for two three-year PhD positions. The position is located at Campus Grimstad, Norway. The starting date is as soon as possible or to be negotiated with the Faculty.
The PhD student will be supervised by researchers from the Intelligent Signal Processing and Wireless Networks (WISENET) Lab, Faculty of Engineering and Science, UiA.
Brief Information about the WISENET Lab
The herein announced position will be part of the recently established Intelligent Signal Processing & Wireless Networks (WISENET) Lab. The Lab activities span across the Department of Information and Communication Technology and the Department of Engineering. The researchers in the WISENET Lab have a strong expertise in a range of areas, among them, Data Science, Machine Learning, In-Network Processing and Distributed Artificial Intelligence for Wireless Communications, Networked Cyber-Physical Systems and Embedded Systems. The Lab has led a number of large research projects, funded by the Research Council of Norway, the EU research Programs FP7 and H2020, as well as national and international industries. WISENET Lab is in rapid expansion, having at present seven PhD students and three postdoctoral researchers working on multiple cutting-edge research projects, such as FRIPRO TOPPFORSK, SFI, PETROMAKS, IKTPLUSS and INFRASTRUCTURE projects. WISENET Lab is committed to achieving international research excellence; please see the notes about prospective PhD students at WISENET here before applying.
The open PhD positions are offered in the area of self-organized wireless networks enabled by direct device-to-device (D2D) simultaneous links employing novel dynamic spectrum access (DSA) features, aiming at progressing substantially over the state-of-the-art both in terms of theoretical aspects (fundamental performance analysis) and algorithm designs. The activities are mainly driven by a multi-disciplinary advanced research project on next generation wireless communications enabled by self-organized spectrum cartography (WISECART). WISECART is funded by the Research Council of Norway (RCN) under the research funding framework “FRIPRO Toppforsk’’, which is the most competitive and highly reputed funding program from the RCN for fundamental research across all disciplines.
Research topics for the positions
The ever-increasing demand for ultra-high data rates and energy efficiency in radio access networks (RAN) together with the need for enabling different types of user-driven applications poses enormous challenges. In this context, D2D communication is being investigated in the wireless communication research community as a promising paradigm to boost both spectrum utilization and energy efficiency. To this end, D2D communication exploits the spatial proximity of devices, which enables direct exchanges of data and control information, i.e., bypassing the base station. As a consequence, higher spectrum reuse can be achieved by enabling multiple D2D communication links while meeting the communication needs for different types of services or applications involving nearby users.
In WISECART, the main goal is to scale up D2D communication to enable a self-organized networking among multiple and heterogeneous devices for purposes such as sharing contents of common interest, increasing connectivity, or intelligently performing certain cooperative tasks. These networks are expected to include not only human operated devices but also machine type communication devices and other objects, as motivated by the paradigms of Internet of Things (IoT) and Cyber-Physical Systems (CPS).
Your research may cover physical, MAC and network layers. In addition to theoretical advancements and algorithmic design, the PhD positions will involve simulation and experimental validation.
The main topics for the PhD positions will be:
- High-resolution localization methods to enable the construction of spectrum maps, by solely relying on the information-bearing signals. This dramatically reduces the overhead of control traffic, which needs to be kept minimal so that the complexity of localization and interference map construction scales well as a function of the number of nodes. The algorithms will be attuned to the specific user activity and traffic patterns. 5G and next-generation waveforms are of special interest to this task.
- Coordination protocols to build, maintain and adapt D2D-based topologies of spectrum sensors that are used to maintain the spectrum awareness, including: (i) neighbor and topology discovery protocols; (ii) sampling protocols capable of dealing with irregular and time-varying sampling caused e.g. by loss of connectivity, node mobility, and synchronization issues; (iii) efficient distributed in-network computation, machine learning techniques and storage of interference maps, minimizing local storage requirements and maximizing the efficiency for accessing interference maps.
- Adaptive user-driven network protocols: (i) Control-plane network protocols to support the generation and maintenance of mesh-type formations for local communications with low control overhead, by considering the trade-off between the level of automatization of the local topologies among the nodes that find themselves co-located and engaged in a given application, and the control that should be guaranteed to the users over the activities of their devices; (ii) Data-plane network protocols to provide specific MAC and routing algorithms for communication within mesh-type formations, considering application requirements and traffic patterns, such as distribution of multimedia content and distributed computation. We will design protocols for scheduling and in-network caching in delay tolerant scenarios, making use of distributed dynamic storage at nodes and ensuring that transmission resources among the nodes are used according to the link qualities (e.g. channel gain maps), demand profiles, storage capacity and energy availability at nodes. We will also explore the use of mm-waves for communications to nearby nodes.
Each one of the two PhD positions will cover one or at most two of the topics described above. In addition, the work will involve also the development of some software architectures that will be used to implement the designed algorithms.
