Dynamic Communications Re-planning Using a Vector Symbolic Architecture

Military / Coalition Issue

The Military relevance of this task is in a future coalition context where analytics applications can be automatically composed of sensors and services that may be distributed across the coalition network and owned by different coalition partners. This is sometimes referred to as the Internet of Battlefield Things (IoBT). How is it possible to discover the required component services and compose the necessary workflows to perform distributed analytics tasks? Is it possible in contested environments to be resilient against network fragmentation and loss of computational assets?

Core idea and key achievements

The core idea is that sensors, data and services (essentially anything) can be described as symbolic semantic binary vectors. Essentially everything is described as a vector of vectors. These vectors have mathematical properties that can be exploited to provide a new way of performing service decentralized peer-to-peer service discovery with no requirement for centralized control. Our key achievement has been to show how to create these vectors from service and sensor descriptions and how these vectors can be bundled together to create new vectors that describe the service workflows that describe the required analytics applications.

Implications for Defence

Using vector representations of sensors, data and services provides an important new way to rapidly configure available assets to perform new tasks in highly dynamic military operations. In a coalition setting the use of semantic vector representations offers the potential to discover and make use of assets owned by other coalition partners to perform required tasks.

Readiness & alternative Defence uses

We have already demonstrated that how the vector representation can be used to perform tasks such as dynamic communications re-planning and to discover and orchestrate NATO Future Mission Network (FMN) services. These demonstrations have used representative simulations of mobile ad-hoc networks (MANET) environments. Higher technology readiness levels (TRLs) could be archived by demonstrating the technology operating in actual wireless networks.
