Nexus - Middleware for Decentralized Service-Oriented Information Fusion
Abstract
We present Nexus a robust and scalable middleware for decentralized service-oriented information fusion. As a project in the UK Ministry of Defense, Defense Technology Center, Nexus is driven by the goals of Network Enabled Capability (NEC). It provides support for discovering, structuring and fusing information key operations enabling the NEC vision. It is built on top of three key concepts--- service oriented computing based on web services, a peer-to-peer architecture and goal-oriented automatic service composition. Combining these three concepts, Nexus delivers agile information fusion capability via a loosely collaborating set of information and fusion services deployed in the service network. Although no strict restrictions are imposed, the fusion services are supposed to provide a higher-level fusion capability on the level 2 and 3 of the JDL data fusion hierarchy [12]. Implementation of peer-to-peer service oriented information fusion based on JXTA and web services is described, together with a demonstration application exploiting these fusion capabilities to support an emergency response scenario.
