“…Previous approaches on the development of context-aware services have largely been at the design [2] or implementation stages [12,14] of the software lifecycle. In [14], the authors propose an approach to include context in the composition of Web services.…”

“…There has been significant recent interest within the pervasive computing community for representing context-aware services at different stages of the software lifecycle. However, most of these efforts have concentrated on the design [2] or implementation stages [12] while little work has been done during the initial phase of design, such as architecture design.…”

With the proliferation of ubiquitous computing devices and mobile internet it is envisaged that future pervasive services will be increasingly large-scale and operate at an inter-organizational level. Therefore, designing and implementing pervasive services will be a more complex and challenging task. Building software architectural models of concurrent and distributed pervasive services and their compositions provide engineers a better understanding of how these complex services inter-operate and help uncover any errors during the early stages of the software lifecycle. In this paper, we propose a novel approach based on behavioral modeling and analysis techniques for representing pervasive software services and verifying process behavior of these models against specified system properties. As part of ongoing research, we model the crosscutting context-dependent behavior of our services as aspect-oriented models using a custom Unified Modeling Language (UML) profile, and apply model transformation techniques to automatically translate the aspects into state machine based behavioral representations to facilitate rigorous software process analysis. The approach is explored using an existing case study in transport and logistics.

“…We employed up to 9 Boolean BDD variables to encode our scenario, corresponding to a model of size 2 9 . Notice that the properties presented above could not be checked using a standard model checker, because of the introduction of conditions over transitions and because our requirements reason about these conditions over transitions.…”

“…Among others, semantic web services technologies [23] are one way to deliver the required metadata to services. Some frameworks and architectures such as SOCAM [14], MyCampus [33] and CACS [22] are examples of the usage of semantic information (ontologies) agents to discover, compose, select and execute automatically services based on context information.…”
