Many pervasive services are embedded in smart homes. It is a great challenge to schedule these services due to the heterogeneity and the mobility of devices. In this article, we elaborate a context-aware service scheduling framework (CASSF), which discovers available services hosted on those heterogeneous and mobile devices, selects suitable services that meet task requirements (TR) and ultimately enhances user experience with content adaptation. Contributions of this article are in three folds. First, the device ontology is designed to describe device features including built-in services, which benefits the knowledge sharing and facilitates the service discovery; second, a context-aware service selection mechanism is proposed, in which available services and contexts including user situations, TR, device capabilities, etc. are taken into consideration. Furthermore, due to the heterogeneity and the diversity of devices, the content adaptation is introduced in the framework to improve user satisfaction. Based on the CASSF, a multimedia prompting system is implemented to assist the elderly with intelligent services, and the evaluation of the proposed framework is performed in term of the execution time. The experimental results showed the framework is feasible and effective.

“…Most of these service discovery protocols are implemented in service-oriented middleware platforms. Konark [4], and DEAPspace [5] and PDS [11,15] have investigated the service discovery and delivery issues in ad hoc networks with middleware platforms. DEAPspace provides a support for the discovery and the delivery of services in wireless single-hop ad hoc networks.…”

Opportunistic networks are one of the most interesting evolutions of the mobile ad hoc networks. In opportunistic networks, mobile devices can communicate with each other even if a route connecting them does not exist all the time. These networks have recently appeared as relevant supports for ubiquitous and pervasive computing.This paper presents a proxy-based model for an enhanced provision of application services in opportunistic networks. This model makes it possible for service providers to specify what services can be delivered by proxies, and what mobile devices are expected to act as proxies. The proxy selection can be performed either in a distributed and autonomic manner or in a centralised manner. This paper also presents some results of the evaluations of this model we have performed using simulation techniques.

“…Work on service discovery in mobile ad hoc networks focuses on using decentralized architectures to overcome the limitations of traditional discovery mechanisms, such as SLP [3], Jini [4], and UPnP [5], that rely on fixed infrastructure. Research in service discovery architectures for such mobile environments can be classified into lowerlayer service discovery protocols [8][9][10][11] and higher-layer service platforms [12][13][14].…”

Abstract. Existing approaches to service discovery have been developed primarily for environments with a fixed network backbone and typically rely on centralized components being accessible to potential service clients at any given time. The characteristic lack of a designated service infrastructure in combination with the highly dynamic nature of the underlying network topology renders such discovery mechanisms unsuitable for mobile ad hoc environments. This paper presents an approach to the discovery of ad hoc services that exploits the fact that the relevance of such services is often limited to specific geographical scopes. Service providers define the areas (proximities) in which their services are available. Clients register interest in specific services and are subsequently informed whenever they enter a proximity within which these services are available. Since ad hoc services can be stationary or may be moving with the location of their mobile providers our approach supports discovery of services with fixed locations as well as of those that migrate with their providers. Our approach has been implemented as a push-based proximity discovery service and its evaluation demonstrates that it is well suited for highly dynamic networks as it maintains neither routes nor overlay network topologies.
