“…Jeckle's and Zengler's Active UDDI [28] is an extension to the UDDI's invocation API in order to enable fault-tolerant and dynamic service invocation. It is able to detect changes in availability of services and replaces unavailable services with alternative ones from the registry, which provide the same functionality.…”

Web services are gaining high popularity and importance on mobile devices. Connected to ad-hoc networks, they provide the possibility to establish spontaneously even complex service-based workflows and architectures. However, usually these architectures are only as stable and reliable as the underlying network infrastructure. Since topologies of mobile ad-hoc networks behave unpredictably, dependability within them can be only achieved with a dynamic replication mechanism. In this paper we present a highly flexible solution for replication and synchronization of stateful Web services and discuss the behavior of the implemented prototype in large-scale simulations.

Abstract-Service-oriented architecture has become the standard paradigm for software component integration. However, with the permanently increasing amount of available services and dynamic changes, the complexity of such service infrastructures, their maintenance, and consequently the expenditures spent for their operation increase equally. To deal with these effects, an improvement of service composition and discovery becomes necessary, especially a higher degree of automation. Following the idea of Autonomic Computing, which similarly aims at automating processes and workflows to a high degree, service composition and discovery have to proceed autonomously, which will on the one hand side reduce human involvement to a minimum, but on the other side require certain capabilities on the part of these mechanisms. For these purposes, in this paper we define prime criteria that have to be fulfilled for an autonomic service discovery. Based on that we present a comprehensive survey on existing service discovery approaches and evaluate to which extent they already fulfill these criteria. As a result, the paper reveals that there already exist some approaches that support or even fulfill a couple of the proposed criteria, which principally enables autonomic properties, but what is missing is an holistic approach focusing explicitly on providing autonomic properties.

“…Recently, several research initiatives have identified the need for enhanced service directories (Akkiraju et al, 2003;Jeckle and Zengler, 2002;ShaikhAli et al, 2003) or extended service descriptions. The WASP project (Pokraev et al, 2003) extends the functionality of UDDI by introducing UDDI+, an attempt to improve the existing service discovery mechanisms regarding semantic and contextual features.…”

In modern heterogeneous environments, such as mobile, pervasive and ad-hoc networks, architectures based on web services offer an attractive solution for effective communication and inter-operation. In such dynamic and rapidly evolving environments, efficient web service discovery is an important task. Usually this task is based on the input/output parameters or other functional attributes, however this does not guarantee the validity or successful utilization of retrieved web services. Instead, non-functional attributes, such as device power features, computational resources and connectivity status, that characterize the context of both service providers and consumers play an important role to the quality and usability of discovery results. In this paper we introduce context-awareness in web service discovery, enabling the provision of the most appropriate services at the right location and time. We focus on contextbased caching and routing for improving web service discovery in a mobile peer-to-peer environment. We conducted a thorough experimental study, using our prototype implementation based on the JXTA framework, while simulations are employed for testing the scalability of the approach. We illustrate the advantages that this approach offers, both by evaluating the context-based cache performance and by comparing the efficiency of location-based routing to broadcast-based approaches.
