IoT devices are being used in a wide range of applications, including healthcare, and smart cities. To perform sensing of their environment, IoT devices are typically deployed as a distributed system. There has recently been increased interest in these devices to perform more complex tasks. One issue is that many of these devices have limited processing power, data storage, power storage, and other constraints. Because of these resource constraints, IoT devices will be unable to perform computationally expensive tasks such as machine learning and will require support from more powerful computing devices. One possibility could be an Edge-based digital twin for the machine learning-based process running on the IoT device, where the computation could be offloaded. While there are numerous potential benefits to this compatible digital twin system, implementing these solutions will necessitate careful planning and consideration of trust establishment and privacy if maximum benefits are to be realised. The computation offloading between the digital twin and its physical counterpart will require trustable, secure, and privacy-conscious communication.
This project aims to accelerate the development of a digital twin by implementing trustable computation offloading. It will extend the life of the IoT network by offloading heavy computations to the network's more powerful devices and will develop novel models to support the development of trustworthy computation offloading based on digital twins. It is an interdisciplinary research project within the School of Computing that combines research expertise and previous research results in IoT trust establishment, machine learning, and pervasive computing.
Applicants should hold, or expect to obtain, a First or Upper Second Class Honours Degree in a subject relevant to the proposed area of study.
We may also consider applications from those who hold equivalent qualifications, for example, a Lower Second Class Honours Degree plus a Master’s Degree with Distinction.
In exceptional circumstances, the University may consider a portfolio of evidence from applicants who have appropriate professional experience which is equivalent to the learning outcomes of an Honours degree in lieu of academic qualifications.
If the University receives a large number of applicants for the project, the following desirable criteria may be applied to shortlist applicants for interview.
The University offers the following levels of support:
The following scholarship options are available to applicants worldwide:
These scholarships will cover full-time PhD tuition fees for three years (subject to satisfactory academic performance) and will provide a £900 per annum research training support grant (RTSG) to help support the PhD researcher.
Applicants who already hold a doctoral degree or who have been registered on a programme of research leading to the award of a doctoral degree on a full-time basis for more than one year (or part-time equivalent) are NOT eligible to apply for an award.
Please note: you will automatically be entered into the competition for the Full Award, unless you state otherwise in your application.
The scholarship will cover tuition fees at the Home rate and a maintenance allowance of £19,000 (tbc) per annum for three years (subject to satisfactory academic performance).
This scholarship also comes with £900 per annum for three years as a research training support grant (RTSG) allocation to help support the PhD researcher.
Due consideration should be given to financing your studies. Further information on cost of living
