This paper proposes a novel middleware for service selection in mobile ad-hoc networks with a particular focus on scenarios immediately and subsequently afterwards an emergency. The proposed middleware, operating on a mobile user’s hand-held device and collecting the user’s contexts through machine-to-machine connectivity, has three major contributions as compared to the current literature. The middleware,...
Service-Oriented Architecture (SOA) is a software paradigm with a uniform means to offer, discover, compose services' capabilities to meet desired effects with measurable performance expectations. While most of today's SOA tools support service process compositions by considering only functional attributes, additional support for composing service processes by non-functional attribute is needed. In...
Context-aware service provisioning for mobile phones is challenging because of diverse user contexts and mobile applications. The context recognition process generally reduces the device performance due to the competitive use of limited resources in the mobile phone. While extensive attempts have been made to provide appropriate services based on user context, previous work is limited to supporting...
Mobile devices like PDAs or mobile phones have become widespread. Similarly network functionality like GSM, Bluetooth or WLAN has become a standard. Nevertheless, not many applications take mobility into account. An application and its communication component are tightly coupled and the application assumes that network behavior does not change. Here in this paper we propose a new lightweight architecture...
Component integration plays a decisive role in service-oriented architectures (SOAs). The technical implementation must faithfully reflect business and enterprise integration requirements. This implies a good understanding of the globally observable message choreography but also of how messages are handled by the involved components and by the SOA middleware. In this paper, we present a solution to...
This paper describes a service-oriented self-configurable middleware architecture to support autonomous sensor networks. Scheduling and load balancing that is integrated in our proposed service-oriented middleware achieve self-configuration. If an error occurred in a self-configurable network it is able to overcome it by different services, that makes the network more reliable and stable. In the case...
Service-oriented architecture supports the dynamic establishment of composite services issued from different organizations and delivers a large spectrum of innovative services. In such distributed environment, authentication and authorization processes require flexible access control to deal with heterogeneous services' directories and dynamic network of identity providers. Federated identity management...
