The current generation of connected devices and the Internet of Things augment people’s capabilities through ambient intelligence. Ambient Intelligence (AmI) support systems contain applications consuming available services in the environment to serve users. A well-known design of these applications follows a service architecture style and implement artificial intelligence mechanisms to maintain an awareness of the context: The service architecture style enables the distribution of capabilities and facilitates interoperability. Intelligence and context-awareness provide an adaptation of the environment to improve the interaction. Smart objects in distributed deployments and the increasing machine awareness of devices and people context also lead us to architectures, including self-governed policies providing self-service. We have systematically reviewed and analyzed ambient system governance considering service-oriented architecture (SOA) as a reference model. We applied a systematic mapping process obtaining 198 papers for screening (out of 712 obtained after conducting searches in research databases). We then reviewed and categorized 68 papers related to 48 research projects selected by fulfilling ambient intelligence and SOA principles and concepts. This paper presents the result of our analysis, including the existing governance designs, the distribution of adopted characteristics, and the trend to incorporate service in the context-aware process. We also discuss the identified challenges and analyze research directions.

“…On the other hand, we try to integrate them within the server side, which does not rely on any capability of clients. Ahn and Nah (2010) proposed a Web service framework based on service-oriented architecture, called LOCA (LOcation-based Context-Aware Web services) framework. LOCA discovers available Web services based on client location information and preference.…”

Purpose-The purpose of this paper is to develop a facade for seamlessly using locating services and enabling easy development of an application with indoor and outdoor location information without being aware of the difference of individual services. To achieve this purpose, in this paper, a unified locating service, called KULOCS (Kobe-University Unified LOCating Service), which horizontally integrates the heterogeneous locating services, is proposed. Design/methodology/approach-By focusing on technology-independent elements [when], [where] and [who] in location queries, KULOCS integrates data and operations of the existing locating services. In the data integration, a method where the time representation, the locations and the namespace are consolidated by the Unix time, the location labels and the alias table, respectively, is proposed. Based on the possible combinations of the three elements, an application-neutral application programming interface (API) for the operation integration is derived. Findings-Using KULOCS, various practical services are enabled. In addition, the experimental evaluation shows the practical feasibility by comparing cases with or without KULOCS. The result shows that KULOCS reduces the effort of application development, especially when the number of locating services becomes large. Originality/value-KULOCS works as a seamless facade with the underlying locating services, the users and applications consume location information easily and efficiently, without knowing concrete services actually locating target objects.

“…[4,5]. Location-based services in ubiquitous computing environments is a rich domain of research [6][7][8][9], in which services make use of location information in particular to better provide relevant ubiquitous services. The application of location-based services is popular in many domains such as navigation and traveler services [10,11], shopping and entertainment services (e.g.…”

With the huge number of offerings in the mobile application market, the choice of mobile applications that best fit particular objectives is challenging. Therefore, there is a demand for a platform elevating the momentum of mobile applications that can adapt their behavior according to the user's context. This paper proposes AppaaS, a context-aware platform that provides mobile applications as a service. AppaaS uses several types of context information including location information, user profile, device profile, user ratings, and time to provision the best relevant mobile applications to such a context. AppaaS supports state preservation, where user-specific data and application status are stored for the user's future reference. Experimental validation demonstrates that AppaaS alleviates the burden on mobile users to find applications that work best for a particular situation. It also enables application providers to dynamically control access to the functionality of their applications. Performance evaluation results show that AppaaS can employ cloud elastic resource provisioning to offer flexible scalability, while satisfying certain QoS constraints. Experimental results also support a conclusion that with little overhead handling context information, AppaaS can bring remarkable benefits to provisioning mobile applications as a service.
