“…Based on these concepts, we have addressed in [6] the composition of mobile distributed systems at both middleware and application level by modeling functional and nonfunctional properties of services and introducing conformance relations for reasoning on composability. Building on this work, we introduce in this section semantic modeling of mobile services so as to offer enhanced support to the interoperability requirements of mobile distributed systems.…”

“…Capability is further related to a set of messages employed in the related conversation; class Message is used to represent such messages. Conversations are specified as processes in the π-calculus [4], as introduced in [6]. We model communication between service components as exchange of one-way messages.…”

“…Conformance in terms of interaction protocols is checked over the associated π-calculus processes, as detailed in [6]; this implicitly includes the realized interaction models. For interaction models, conformance may alternatively be asserted by semantic reasoning on the related individuals of class Connector.…”

“…However, interoperability requirements of mobile distributed systems are wider, concerning functional and non-functional interoperability that spans both middleware and application level; conformance relations enabling reasoning on interoperability are further required. In our previous work [6], building on software architecture principles, we elaborated base modeling of mobile software components, which integrates key features of the mobile environment and allows for reasoning on the correctness of dynamically composed systems with respect to both functional and non-functional properties. Building on this work as well as on SOA and Semantic Web principles, we introduce in this paper semantic modeling of mobile services to enable interoperability and dynamic composition of services.…”

“…Specifically, we introduce OWL-based ontologies to model the behavior of mobile services, which allows both machine reasoning about service composability and enhanced interoperability. We note that our focus is on the functional behavior of services; specification of the non-functional behavior of services and definition of related ontologies is part of our future work, still based on [6]. We further point out that our approach to interoperability is generic, thus, it may as well apply to non-mobile systems.…”

Abstract. Today's wireless networks and devices support the dynamic composition of mobile distributed systems according to networked services and resources. This has in particular led to the introduction of a number of computing paradigms, among which the Service-Oriented Architecture (SOA) seems to best serve these objectives. However, common SOA solutions restrict considerably the openness of dynamic mobile systems in that they assume a specific middleware infrastructure, over which composed system components have been pre-developed to integrate. On the other hand, the Semantic Web introduces a promising approach towards the integration of heterogeneous components; current semantics-based approaches are, however, restricted to application-level interoperability. Combining the elegant properties of software architecture modeling with the semantic reasoning power of the Semantic Web paradigm, this paper introduces abstract semantic modeling of mobile services that allows both machine reasoning about service composability and enhanced interoperability at both middleware and application level.

Abstract. The emergence of portable computers and wireless technologies has introduced new challenges for middleware. Mobility brings new requirements and is becoming a key characteristic. Mobile devices may move around different areas and have to interact with different types of networks, services and may be exposed to new communication paradigms. Thus, mobile distributed systems need to dynamically detect and adapt their interaction protocols to interoperate with services available in the environment. As a result, middleware for mobile devices must overcome two heterogeneity issues to provide interoperability in the mobile environment, i.e, heterogeneity of discovery protocols and of interaction protocols between services. Whereas adaptation techniques from reflective middleware are suitable for the latter, it is more problematic for the former if both issues are addressed concurrently. Specifically, reflective mechanisms consume too many resources like bandwidth, memory and CPU, which are limited on the mobile devices. This paper first highlights why current solutions to interoperability fail to realize service discovery protocol interoperability with both high performance and low resource consumption. Second, this paper addresses this open issue by using software architecture concepts enhanced with event-based parsing techniques to provide efficient, lightweight and flexible mechanisms to bring full service discovery interoperability to any existing mobile platform.

Abstract. In this paper we motivate an Architecture Description Language (ADL) for mobile distributed systems based on the π-calculus. Different from other approaches, the non-functional properties, which are essential when mobile architectures are described, are treated in a flexible manner by inserting logical formulae for expressing and checking non-functional properties into π-calculus processes. A formal example is given to illustrate the approach before the constituents of the ADL are sketched.
