Lead Research Organisation: University of Essex
Department Name: Computer Sci and Electronic Engineering


Higher rates, lower latencies, and lower energy consumptions: Future communications systems and most of their applications rely on significant improvement in these three directions which are conflicting in nature. Fast and reliable communication infrastructure is essential for advancements of various industries: from mobile broadband to intelligent automotive cars, from smart cities to smart grids, or from telemedicine to haptic communications. These applications are vital for higher human life quality and rapid economic growth. The prospect of fast future communications will not be possible unless a fine tuning between all of the above three conflicting requirements is achieved, which has proved to be challenging over the past years.

Adaptive radio resource allocation (RRA) techniques that efficiently manage the system resources have shown promising improvements when considering only one or two of these directions. On the other hand, energy harvesting technologies are emerging as a promising solution for reducing energy consumption of the communication devices, while maintaining the system throughput. Despite the challenging nature of improving the system performance in all of the above three directions, because of the recent progress in the adaptive RRA techniques and energy harvesting technologies, it is now the time to tackle this challenge. Coupling the RRA techniques and energy harvesting technologies has a great scope to significantly improve the overall system performance, which is yet to be exploited. This project aims at developing novel cross-layer RRA techniques that benefit from energy harvesting technologies and optimally tune the system parameters to flexibly optimize the trading between rate, delay and energy consumption.

Planned Impact

The project impact plan is designed to maximize the impacts of the project results on the potential beneficiaries, listed as

1: Academia: Academic and research communities across different disciplines can benefit from the gained knowledge of this project. Researchers concerned with theoretical and practical aspects of wireless communications and networking, signal processing and low-power communications devices can benefit from the gained knowledge of this project. The project results will be published in several well-known journals and conferences. The PI will present a keynote in CROWN workshop at Lancaster University and will also apply for tutorials in ICC and GlobeCom. Two research visits will be planned to further extend the project's academic impacts.

2: Telecommunication industries: Since the project deals with fundamental requirements of future wireless networks, the project outcomes will be useful for UK and international Telecommunications industries. The results of WP1 provide fundamental and useful understanding of the system performance that is critical for communication systems design and developments. The proposed transmission techniques of WP2-WP4 also provide a foundation for design of future transmission protocols. We utilize our industry link with Rinicom to validate and assess the applicability of our results for practical situations that are concerns of the communication industries. Rinicom will provide us with access to its testbed and platform at its Lancaster location. We will utilize the locality of the company and plan to either visit the company every three months, or invite a member of the company to our meetings at the university. The PhD student will be encouraged to take the intern-ship offer of the company, which will help her/him to gain experience of applying the proposed algorithms of WP2 and WP4 in practical networks settings.

3: Other industries: The merger of different disciplines is bringing into picture possibility of exciting new applications. The transfer of skills through communication links, also coined as haptic communications, requires robotics and communications industries and researchers to work together. The possibilities of very low-power communications devices through energy harvesting is appealing to healthcare services. The sustainable sensor networks through energy harvesting are useful in military applications. The various industries involved with these technologies can indirectly benefit from the outcomes of the project.

4: General public: The ultimate beneficiaries of the project outcomes will be the general public. There are countless applications that can emerge if the communication networks can overcome the current inadequate performance shortfalls. These applications, for example, smart cities, can improve the quality of human life. A project website at Lancaster University domain will be created to provide timely updates of the project news and outcomes to public access. Short technology news will be distributed through Lancaster University news website. We use social media to announce the outcomes, news and events related to the project.

5: Project staff: The project will be an excellent opportunity for the RA who can build on his/her research background and gain valuable research training during the work of the project, interaction with Rinicom, and also through the planned academic visit. The project is also a good opportunity for the PhD student, who will be hired through studentship offered by the SCC as a support for this EPSRC first grant proposal, to gain research and practical skills as working part of a group and through Rinicom intern-ship. Finally, the PI will benefit from the project through gaining experience in project management and preparing a foundation for a longer research program that aims at facilitating a cross-discipline research framework that will focus on enabling new applications for communication systems.
Description As part of the work that was carried out we discovered and proposed:1: a practical simple tradeoff relation between EE and SE of systems with low latency requirement was developed and tested. The result was published in an IEEE Transactions on Communications. 2: A closed-form expression for the performance of a cooperative relying channel with energy harvesting technologies both at the transmitter and at the relay was found. These results were tested using Matlab simulations. these findings were published in IEEE Transactions on Communications.
Further results are published in two journal papers in IEEE Transactions on Communications in 2018 and 2019.
Exploitation Route The PI is engaged with creative industries through a project proposal submission on how to improve the productivity of freelancers and micro-businesses using digital connectivity. The project proposal has gone through the first stage.

The first stage and second stage of this bid were successful, but the last stage was not. The PI will keep working and reaching out to other research disciplines that could benefit from the outcomes of this project.
