DST is developing Survivable, Communications and Autonmous Delivery Service (SCADS), an autonomous swarming framework that supports ‘data-ferrying’ to allow the exchange of user information when end-to-end connectivity cannot be achieved, including urban environments, where line of sight cannot be achieved, or denied RF environments, where an adversary seeks to prevent RF communications.
In such environments, SCADS makes use of additional autonomous assets (e.g., Unmanned Airborne Vehicles –UAVs) bearing communications resources and leveraging delay tolerant network protocols to provide communications between disconnected nodes. SCADS uses emergent behaviour techniques to minimise the coordination management traffic required between nodes, avoiding the need to centrally control them.
This presentation will cover the underlying research into multiple data-ferrying behaviours operating in difficult environments will be presented, as well as results from a recent successful real-world trial providing data-ferrying between disconnected ground nodes using multiple UAVs.
