Probabilistic Model Checking Techniques for Drone Swarms

Lead Research Organisation: Imperial College London
Department Name: Computing

Abstract

We will investigate the use of probabilistic model checking techniques to verify drone swarm systems. This will involve extending these techniques to enable modelling of systems where the size is potentially unbounded and not known at design-time. We will also develop tools that implement these techniques and demonstrate their applicability on protocols from swarm robotics.

Description This award developed new techniques to verify the behaviour of systems that involve an unknown number of participants. Some examples of such systems include drone swarms, network protocols, and Internet of Things devices. While techniques have previously been developed to verify these, they did not cover the case of probabilistic systems, where the outcome of actions is not fixed but instead follows a probability distribution. In this award, we have created new techniques for addressing the verification of these unbounded probabilistic systems, and implemented them into a software package. We gave some example applications of our toolkit to verify a number of scenarios, with a particular focus on case studies from swarm robotics.
Exploitation Route The software package developed in this award could be used by other researchers and/or people in industry in order to verify further systems. Additionally, the techniques developed could be further expanded with additional research in order to enable the modeling of even richer scenarios.
