Results in brief
Reconfigurable intelligent surfaces-based energy harvesting sustainable wireless communication systems.
The project RISESWCS was dedicated to the study and research of RIS assisted energy harvesting wireless communications. In this project, the key goals were to analyze and optimize the performance of RIS assisted communication systems while also providing energy (wirelessly) to ambient users. This was a very timely topic for research due to the exceedingly large number of low power devices that will be deployed in near future where the need for replacing batteries is difficult to fulfill. Specifically, four key research objectives were devised as given below: 1-Characterize the mathematical relationship between average performance metrics such as data rate, outage probability, and EH efficiency; and the system parameters such as number of RIS elements, total transmit power, and transmission bandwidth. Work package 1 (WP1), carried out at TAU, aims at achieving RO1. RO1 is measurable and verifiable by analytical formulations and relationships obtained for performance metrics and system parameters. 2-Building on the groundwork of RO1, develop optimization algorithms for maximizing the performance under practical limitations on the feedback requirements and subsequently devise low complexity distributed implementations of the developed optimization algorithms. RO2 will be achieved at TAU through WP2. RO2 is measured and verified by the developed optimization algorithms. 3-Develop a simulation software toolbox for easy verification and demonstration of the newly obtained results. This toolbox will be named RISESWCS and can be exploited both in academia and industry. RO3 will be achieved through WP3 at TAU. The success of RO3 is measured and verified by the developed toolbox. 4-Provide abstractions of the results of RO1 for encompassing the large-scale network analysis to assess the feasibility of the large networks and to devise cross-layer optimization techniques for efficient use of available resources. WP4 will be responsible for achieving RO4 and the tasks of WP4 will be partially carried out at TAU and UVIGO. This feasibility study will provide measurable and verifiable performance tradeoffs as function of system parameters.

Project objective
The essential role of digital technologies in modern society together with the profound changes introduced are reflected in the second Digital Agenda for Europe: 2020-2030 which is focused on radically improving digital infrastructure and providing ubiquitous public services by 2030 through gigabit connectivity in a low cost manner. This project considers low cost reconfigurable intelligent surfaces based energy harvesting sustainable wireless communication system (RISESWCS) for substantially improving the physical layer and medium access layer performance of the future wireless communication systems. Moreover, this project will provide a practical feasibility study for employing low cost RISs as a radio access network technology for a large scale wireless powered communication network with wideband transmissions. The project will systematically begin with the analysis, optimization of the RISESWCS at the physical layer and provide the performance analysis and optimization techniques for improving the data rate, coverage and energy efficiency at the physical layer. In this step, the practical aspect of the project will be ensured by carrying out the analysis and optimization by incorporating the realistic scenario into the system model which include imperfection in the channel state information, centralized overhead information unavailability and dependence of the reflecting angles in RIS elements on impinging frequencies. Then, the research will be extended to incorporate the medium access layer (MAC) for providing a holistic view for the large RISESWCS. In particular, MAC layer techniques, in terms of resource block allocations, scheduling and routing mechanisms, will be developed while considering the requirements of 6G wireless networks in terms of different fundamental performance metrics of MAC layer such as collision probability, packet loss and delay. Finally, the project will summarize the feasibility conditions for deploying RISESWCS in a real scenario.
