Science of Sensor Systems Software

Towards a unifying science for smarter sensor based systems

We will deliver new principles and techniques for the development and deployment of verifiable, reliable, autonomous sensor systems that operate in uncertain, multiple and multi-scale environments.


Science of Sensor Systems Software (S4) is an EPSRC programme grant for Glasgow University with Universities of St Andrews, Liverpool and Imperial College running from January 2016 until December 2020.

Research vision

Sensor systems are embedded everywhere: from transportation and lighting, to smart tags and flooded fields, providing information and facilitating real-time decision-making and actuation. Smart cities, internet of things, big data and autonomous vehicles all depend on robust sensor systems that can be trusted to deliver useful, timely and more reliable information.

Extracting information is far from straightforward: sensors are noisy, they decalibrate or may be misplaced, moved, compromised, and generally degraded over time, both individually and as a collective network. Uncertainty pervades the physical and digital environments in which the systems operate. There are increasing requirements to add more autonomy and intelligence, yet we understand very little about programming in the face of such pervasive uncertainty that cannot be engineered away. How can we be assured that a sensor system does what we intend, in a range of dynamic environments? How can we make such a system “smarter”? How can we connect the stochastic nature of environments, the continuous nature of physical systems, and discrete nature of software? Currently we cannot answer these questions because we are missing a science of sensor system software. The S4 programme will develop a unifying science, across the breadth of mathematics, computer science and engineering, that will let developers engineer for the uncertainty and ensure that their systems and the information they provide is resilient, responsive, reliable, statistically sound and robust. The vision is smarter sensor based systems in which scientists and policy makers can ask deeper questions and be confident in obtaining reliable answers, so the programme will deliver new principles and techniques for the development and deployment of verifiable, reliable, autonomous sensor systems that operate in uncertain, multiple and multi-scale environments.


The dashed arrows indicate the elements to be developed: linking software development and sensor system applications, deployment and the frames of reference that determine the dimensions of environment in which the systems operate.

Objectives: To develop the new foundational conceptual frameworks, theories, models, logics and reasoning techniques needed for analysis of capabilities, constraints and requirements of sensor system software.
Leader: Prof Muffy Calder with expertise in stochastic event-based modelling and reasoning, multi-scale and spatial modelling for virtual/physical systems, decision support for event-based condition monitoring, real-time verification, component-based modelling for biochemical systems and probabilistic analysis of software usage.


Objectives: To develop new techniques and tools for the abstract design and formal verification of both individual and ensemble behaviours of autonomous sensor systems.
Leader: Prof Michael Fisher with expertise in practical formal methods, temporal logics, programming languages, and the formal verification of autonomous systems.


Objectives: To develop the approaches that match the formal understanding of the problem space and the mission of a sensor network to its realisation, deployment, and adaptation in the field.
Leader: Prof Simon Dobson with expertise in building adaptive sensor technology to observe complex real-world processes in ways that respect end-to-end scientific constraints.


Objectives: To build a framework that enhances the programmability and maintainability of next-generation sensor/actuator systems at scale and that can also take as dynamical inputs control functionality and verification probes while supplying the data representing the frames of reference as assessed by the framework at run-time as measures of dynamic environmental context.
Leader: Prof Julie McCann with expertise in decentralised algorithms and protocols for low-powered sensing and control systems that dynamically adapt to their environments.


S4 will be driven and validated by end-user and experimental applications involving the following organisations: ABB, British Geological Survey, CENSIS, Freescale, Jacobs, Rolls-Royce, Scottish Canals, Thales, Topolytics, Transport Scotland.
