RFID-based ubiquitous sensing
Automated ubiquitous sensing will represent a major change in current societal challenges in terms of efficiency (i.e. automatization), sustainability (better models and decision-making), and social wellbeing (security and improved job market). Automated ubiquitous sensing would, for instance, detect humidity or thin water ponds on a road avoiding possible car accidents in a smart city context, improve recycling processes thanks to automated items classification, or predict dehydration of a person in an ambient assisted living environment.
Current solutions for automated sensing, including active and passive sensors, use specific circuitry for sensing besides wireless communications technologies to transmit the measurements. This approach implies battery management complexity and/or expensive customized technology, being inappropriate for actual ubiquitous sensing.
This proposal aims to exploit passive low-cost communication technologies like Ultra High Frequency (UHF) Radio Frequency Identification (RFID) to act as ubiquitous sensors, by means of analyzing context effects on the RFID labels performance (i.e. see [1,2,3,4]). The goal is to perform the first steps towards a complete environment digitization thanks to actual ubiquitous sensing.

Context-aware applications for ambient intelligence Smart cities are a new scenario where a variety of data sources open the door to innovative applications, with the final goal of improving the quality of life of citizens, industry competitiveness and government. The Internet of everything is responsible for collecting and transmitting this data at different levels, by using a wide variety of sensors (including peoples' smartphones). We propose to make use of contextual intelligence tools and techniques (like data mining or statistical learning) to process signals (accelerometers, acoustic, etc.) with the overall goal of transforming the above collected data into useful information, enabling new applications or improving existing ones within the ambient intelligence context. |

Ultra-reliable low latency industrial communication technologies The digitalization of the industry is a step further to achieve a digital society. Such digitalization will enable more efficient industries with major impact in the quality of work and the generated industrial value and competitiveness. To achieve such digitalization, massive connectivity will be progressively introduced to industrial processes, mainly by extending existing machinery interfaces and integrating to existing industrial infrastructures and information systems on a first stage. This integration of Information Technologies (IT) and Operational Technologies (OT) by itself imposes challenges beyond what is envisioned by the 5G architectures since, industrial processes are not only critical in terms of reliability, latency and security but also in their architecture, heterogeneity and ownership model which will require more flexible network architectures to complement those envisioned by 5G. In this research proposal we aim to address industrial requirements to support digitalization. The research work will be centered in the study and development of mechanisms to enable ultra-reliable and low latency industrial wireless communications. The envisioned communication technology should support robotics eliminating the need of wires, while ensuring high reliability (99.999%), low latency (<1ms) and secure links. The research work will explore the features provided by novel physical layer technologies, based on mmWave (>30Ghz) bands and exploit redundancy mechanisms to achieve the desired performance.

Sustainable computing
This research proposals aims at taming the energy consumption of computing services in the future Internet. This is a pressing need for a greener society, considering that the worldwide energy consumption of computing facilities is expected to rise to 1/4 th of the world´s electrical energy by 2030. Emerging applications, such as extended reality, smart health, smart factories and autonomous driving, to name a few, require massive amounts of computation resources to process huge volumes of data that will be generated by Internet of things (IoT) devices. Multi-access edge computing (MEC) technology provides such computation services right at the network edge and enables important opportunities to impose stricter and greener computing policies. This proposal will target the edge computing space with the goal of cutting down their carbon footprint, adopting novel green design principles and techniques, and taking advantage of energy harvesting technologies to be installed at the network edge.
The thesis will explore different paradigms for renewable energy origin certification and thus contribute to a trustful green computing. Ideas based on blockchain concepts such as distributed oracles will be explored.
Requirements:
Candidates must have a strong programming background, fluency in English (spoken and written) and excellent analytical and writing skills. Experience in blockchain and smart contract design will be highly appreciated.
In addition to the requirements stated in the call, all candidates applying for this thesis proposal must send a short report describing: i) Computing and blockchain background of the candidate; ii) Programming skills and already developed projects; iii) The research interests of the candidate (within the framework of the proposed thesis). This report must be sent directly to xvilajosana@uoc.edu. Only candidates fulfilling all requirements (general requirements of the call and specific requirements of this thesis proposal) will be considered.

Terrestrial and satellite networks coexistence and complementarities
In this research line we will be analysing the evolution of the communication ecosystem for IoT Satellite networks, following emerging standards such as the LR-FHSS promoted by the LoRaWAN Alliance or the new initiatives driven by the 3GPP consortium under the Non-Terrestrial-Networks (NTN). The goal of the thesis is to develop mechanisms to take advantage of coexisting terrestrial and satellite infrastructures, while mitigating the impact of satellite downlinks and terrestrial uplinks to the nearing base stations. At the ground segment, policies to reduce the potential impact of a numerous set of packet replicas received by the different stations into the backbone infrastructure will be studied.

Next generation of MSX systems MSX was one of the first personal computer standards, developed by Kazuhiko Nishi (西 和彦) in the 80’s, and leading to a family of 8-bit microcomputers that was well known in Japan, parts of Europe (especially, Spain and Holland) and Brazil. This new system was backed by companies such as Sony or Toshiba. Even though relatively niche outside of Japan, it had a sizeable impact in these western countries, introducing japanese aesthetics through what would later become important software companies and franchises (e.g. Konami).
At present time, Nishi himself is creating a new generation of MSX systems. Now, not as personal computers, but as hobbyist home machines with different purposes, such as IoT, supercomputing, or Smart TV systems.
This is a multidisciplinary research line that intends to work with the prototype of the upcoming MSX 0 standard, an M5Stack IoT device that tries to encapsulate many different types of sensor systems. Its main goal is to find its niche in the current ecosystem. This may encompass aspects ranging from the social aspect (investigating the reasons behind retro computing in the 21st century), studying the human-computer interface of the new systems, still based on the 80’s computers, and the design and development of software protocols that enable its sensors systems to function or enhance its capabilities.
Note: There is the possibility that Nishi himself acts as co-supervisor of this thesis, in a more hardware/software oriented thesis.
