Distributed Composition of Highly-Collaborative Services and Sensors in Tactical Domains

Abstract

Software systems are often built by composing services distributed over the network. Choreographies are a form of decentralized composition that models the external interaction of the services by specifying peer-to-peer message exchanges from a global perspective. When third-party services are involved, usually black-box services to be reused, actually realizing choreographies calls for exogenous coordination of their interaction. Nowadays, very few approaches address the problem of actually realizing choreographies in an automatic way. These approaches are rather static and are poorly suited to the need of tactical domains, which are highly-dynamic networking environments that bring together services and sensors over military radio networks. In this paper, we describe a method to employ service choreographies in tactical environments, and apply it to a case study in the military domain.
