“…The composer generates composition plans and stores it in a plan repository in a cloud. Yang et al [72] propose an architecture for mobile Web service discovery, aiming at avoiding intermittent connections and overcoming delay and bandwidth limitations. Their architecture enables mobile users to download and execute services locally in order to avoid unnecessary back and forth communication.…”

Abstract-For many years mobile devices were commonly recognized as Web consumers. However, the advancements in mobile device manufacturing, coupled with the latest achievements in wireless communication developments are both key enablers for shifting the role of mobile devices from service consumers to service providers. This paradigm shift is a major step towards the realization of pervasive and ubiquitous computing. Mobile Web service provisioning is the art of hosting and offering Web services from mobile devices, which actively contributes towards the direction of Mobile Internet. In this paper, we provide the state of the art of mobile service provisioning as it currently stands. We focus our discussions on its applicability, reliability, and challenges of mobile environments and resource constraints. We study the different provisioning architectures, enabler technologies, publishing and discovery mechanisms, and maintenance of up-to-date service registries. We point out the major open research issues in each provisioning aspect. Performance issues due to the resource constraints of mobile devices are also discussed.

“…Although we use the term 'data item' in this paper as a physical representation of the data, data broadcast is not restricted to this as it can also be extended to disseminate types of services on the web [49,50]. Mobile clients, upon receiving information from the mobile broadcast services, (depending on the application type), may request other services based on the information that has been obtained.…”

Mobile broadcast services with MIMO antennae in 4G wireless networks

The deployment of wireless data broadcast to empower mobile information services as a resource-conserving means offers significant benefits due to the scalability feature offered by the technology. In this paper, we present a novel and holistic data broadcast management approach in 4 G wireless networks with multiple-input multipleoutput (MIMO) antennae. The proposed scheme consists of three elements, namely: (i) broadcast ordering; (ii) Global indexing; and (iii) merging data structure. With the integration of these elements, we expect to obtain substantial efficiency for mobile computing clients when retrieving data on-air. We have experimentally evaluated the performance of the proposed model including comparison with the relevant schemes. The results from the experiments affirm the effectiveness of our proposed approach in respect to minimizing query access time and conserving energy utilization of the clients.

“…In broadcast, producers send information over a medium on which consumers can listen. One example, in wireless environments, is that of a mobile service (producer) broadcasting the requested information via a wireless channel [43]. In multicast, information is sent to a specific set of consumers.…”

Abstract-The event-driven, or notification-based, paradigm has attracted much research interest in areas such as distributed systems, databases, workflow, and grid computing. However, little attention was devoted to event-driven service-oriented architectures (SOAs). In this paper, we propose a novel framework for event-based interactions in SOAs. First, we introduce various notification patterns for event-driven SOAs. We define two taxonomies for dissemination protocols in SOAs: The interaction taxonomy identifies the different models through which Web services interact with each other and the filtering taxonomy classifies the events and services involved during dissemination. Second, we propose a dissemination pattern called implicit notification. In contrast to publish-subscribe, implicit notification does not require consumers to explicitly subscribe with producers. We define a model for implicit notifications and introduce a family of protocols for enabling this pattern. Finally, we describe a prototype implementation for a disaster management case study and conduct experiments to assess the performance of the proposed protocols.
