Infrastructures for Smart Cities: Towards Sharing Actuators

Abstract: Smart cities require the deployment of sensors and actuators, connected to a network infrastructure. A number of current solutions are vertical, in the sense that a set of sensors, actuators and even the network, are dedicated to one application (traffic control, light control, …). There is a trend towards horizontal solutions, in which sensors, actuators, and the network infrastructure, can be shared between actors and applications. Sharing sensors, typically between several monitoring applications, is technically much simpler than sharing actuators. In this talk, we will see what it means to share actuators, define a notion of conflicting commands, and see what type of access control protocol can be used to guarantee safety properties and atomicity in the presence of such conflicts. Since actuators influence the physical world, actions cannot be undone. This raises specific problems for the definition of a transaction-like mechanism.
