Pervasive systems are increasingly being designed using a service-oriented approach where services are distributed across wireless devices of varying capabilities. Service orchestration is a simple and popular method to coordinate web-based services but introduces a single point of failure and lacks the flexibility to cope with the greater variability of pervasive environments. Choreography in contrast advocates explicitly modelling systems as interacting peers that conform to rules of interaction. Choreography offers greater reliability and flexibility but leads to systems that are much harder to validate. In this paper we describe a novel intermediate approach, where given a logically centralised service orchestration, we automatically generate a distributed implementation that correctly enforces the orchestration behaviour. Our system handles all the synchronisation and consensus issues and ensures correctness. The system also incorporates a number of abstractions for grouping pervasive peers and coordinating pervasive peer-to-peer interactions.
