The problem facing the security and defence communities is the volume, complexity and timeliness of information. In particular the ability to locate and access the right ICT service at the right time is crucial to achieving real-time responsiveness and situational awareness. The Nexus system is a Peer-to-Peer (P2P) agent-based middleware that creates a fully distributed and highly resilient Service Oriented Architecture (SOA). The combination of a structured P2P overlay network and autonomous service discovery, delivers a powerful capability to support real-time operations in either security or defence applications. This paper outlines the overall architecture of the Nexus system and its application in a defence scenario with a detailed review of the service selection algorithm utilised, termed Mercury. Mercury provides an autonomous, efficient and distributed service selection framework and collaborative algorithms for SOA construction and real-time adaptation.
