“…Cooperative artefacts [23] sport a reasoning engine which is specifically tailored for mobile ad hoc networks. Similar to the Fact Space Model, it offers devices the means to reason about a distributed knowledge base representing their immediate environment using Prolog-like rules.…”

“…Its data-driven reasoning strategy aligns well with the fact that changes to the knowledge base should be promptly reflected in the application's behaviour. This section provides a more thorough analysis of the differences with a goal-driven backward chaining strategy such as the one used in cooperative artefacts [23].…”

“…The underlying reason for this restriction is that in order to respond to the availability of new data, the inference engine needs to be triggered explicitly. For instance, Strohbach et al issue a new attempt to prove a predefined set of goals whenever a change in the distributed knowledge base is observed [23]. Each such attempt completely reconstructs the proof which can be both costly and time-consuming (e.g.…”

Abstract. Coordination languages for ad hoc networks with a fluid topology do not offer adequate support to detect and deal with device disconnection. Such a disconnection is particularly relevant if the device provided context information rather than emitting messages, as such context information then becomes invalid. This paper proposes the Fact Space Model which establishes a logic coordination language on top of Lime's federated tuple space. In the model, the federated space offers applications a consistent view of their environment over which they can reason using logic rules. These rules encode which conclusions may be drawn from the presence of particular facts, and are similarly used to ensure the consistency of these conclusions when devices go out of range. By allowing applications to add application-specific hooks to these rules, the application programmer is offered a general-purpose mechanism to respond to the discovery and disconnection of devices.

“…However, using imperative programming languages, collaboration has to be explicitly programmed as a distributed application. A different approach is the arteFACT framework [10]. It consists of a Prolog interpreter, utilizing business rules in form of Horn clauses and proves for inconsistencies.…”

Collaborative Business Items -or CoBIs -are an approach to build pervasive computing systems in order to support business processes with mobile assets and items. CoBIs enable the delegation of tasks originally located in stationary large back-end systems down to mobile assets and items. For instance, these tasks include the direct, i.e. item-centric, monitoring and detection of hazardous situations like they may occur when working with chemical goods. We refer to this delegation as logic on the items. The items are augmented by sensor technology and made aware of their surroundings and actions imposed on them. Collaboratively, they are able to reason on common states and enforce pre-defined conditions with only temporary support of stationary back-end computer systems. As a result CoBIs allow a more fine-grained, immediate, realtime and stable control of the handling of items. This paper presents the CoBIs fundamentals and results derived from implementations in a workplace safety scenario on handling various chemical goods. The results back up our claim that for the use of business logic in critical -e.g. dangerous -environments relocation of business logic onto items is required.

Abstract. Many programming models have been proposed to facilitate the development of context-aware applications. However, previous work does not offer support for building customised systems and has largely been targeted at a single application domain. In this paper, we describe MoCoA, a flexible middleware framework that permits the rapid development of context-aware applications and supports deployment scenarios ranging from augmented artefacts to city-wide smart-space applications. Crucially, MoCoA supports a small set of programming abstractions that are suitable for building a wide range of context-aware applications for deployment in a fixed or (ad hoc) mobile environment. For each of these abstractions, MoCoA provides a set of implementations via a library of components. We present three applications of the MoCoA framework that demonstrate both the use of the programming abstractions and the flexibility of the framework.
