Communication architecture for autonomous passenger ship

Novel innovations have been witnessed in the past few years in the field of technology for autonomous vehicles. These have been exploited in various applications in the maritime domain; one such application is the proposal to develop autonomous passenger ships (APS) or ferries for carrying passengers in urban waterways. Such technology requires the integration of several components to support the safe and secure operation of the ferries. In this paper, a communication architecture is proposed, that satisfies pre-established communication requirements and supports autonomous and remotely controlled functions of an APS. The architecture was designed using the Architecture Analysis and Design Language (AADL); this enabled an iterative design process to be followed and allows for future improvements. The proposed architecture is verified by showcasing the role of the different architectural components in addressing the requirements and in supporting the expected functions in a number of operational scenarios based on the expected operations of an APS use case called "Autoferry." Furthermore, the proposed architecture has been evaluated by demonstrating its ability to achieve the expected performance according to the requirements, in simulated experiments using the network simulator GNS3.
