PhD Studentship: Service level assurance of Smart Infrastructures (supported by BT)

University of Bristol - Civil Engineering Department

The project:

An EPSRC Industrial CASE award PhD studentship is available at the University of Bristol in collaboration with BT.

The Internet of Things has emerged as a new paradigm able to drive extra efficiencies out of existing city infrastructures, decreasing the size of new investment necessary to meet growth requirements. By installing sensors in a city environment, authorities could get a near real-time view of situations and take appropriate actions to improve citizens quality of life.

BT’s Data Hub approach provides additional benefits through the delivery of a platform to pull sensor data feeds together but also supporting an ecosystem of partners and tools to trade the data; that is the Data Hub brings together Data Providers who make sensor data feeds available with own licences, privacy terms and SLA guarantees and Data Consumers (citizens, app developers or even SMEs) who subscribe to use certain data feeds of interest. In this digital ecosystem, the key challenge is how to guarantee and maintain SLAs, when end-to-end service delivery engages multiple authorities, each authority owing a separate domain of control over the part of the service they are responsible for.

Additionally, with computational logic being pushed to the edge, e.g. analytics closer to gateways and sensors, end-to-end orchestration becomes an overarching concern aimed at optimal co-ordination of multiple aspects of the ecosystem e.g. edge apps (containers), network (NfV), cloud apps, data streams. Also, the physical nature of sensors being devices installed around the city manifests a further SLA challenge: how do we guarantee reliable data feeds from sensors over dire circumstances such as extreme weather conditions or vandalism.

The PhD should focus on techniques and approaches for End-to-end SLA management in an IoT/Data hub ecosystem environment considering areas like:

  • (i) predictive analytics that can foretell trends and could determine a high possibility of disrupting SLAs
  • (ii) how we can best detect problems with feeds and where there have been SLA affecting matters, how to handle reporting these without a large strain of searches etc. on the hub, and how to issue repudiation e.g. service credits
  • (iii) orchestration techniques that optimise deployment of IoT devices, network connectivity parameters, app logic deployment etc, to guarantee end-to-end customer SLAs.
  • (iv)

Candidate requirements: 

We are looking for an enthusiastic student with at least a 2:1 Honours degree or equivalent in Computer Science, Electrical & Electronic Engineering or Communications Engineering.  Candidates should have a deep knowledge of computer networking in a variety of environments (particularly UNIX), excellent understanding of system architectures for big data computation (high performance computing, very large databases), knowledge of Internet of Things networking and data harnessing protocols, understanding of computer security fundamentals.

Funding:

This 4-year scholarship covers full UK/EU (EU applicants who have been resident in the UK for 3 years prior to 1st September 2017) PhD tuition fees and a tax-free stipend at the current RCUK rate (£14,553 in 2017/18) plus an additional ‘top-up’ by the industrial partner (when all contracts are in place).
