With the raising number of Internet services, automatic service discovery will be a very important feature in future network scenarios, e.g., in self organizing ad hoc networks. With service discovery, devices may automatically discover network services including their properties, and services may advertise their existence in a dynamic way. This paper compares some well–known service discovery ...

This paper describes our experience with the use of Universal Description, Discovery and Integration (UDDI) technology for supporting location-based service discovery. Our goal is to allow Web Services to be associated with physical locations and then queried according to spatial criteria. This would enable location-based applications to use local UDDI registries to discover the Web Services th...

Service discovery is a critical aspect in the Service Oriented Computing approach. A model, a methodology and a tool environment based on ontologies are proposed in this paper. The requester and provider perspectives are discussed, both to support the service publication phase and the search phase. The proposed service ontology is based on functional aspects and it is organized on three layers,...

Wireless Mesh Network is an emerging technology that allow users to access information and services electronically using service discovery protocol. The seamless connectivity and mobility feature of WMN motivated us in the design of efficient and scalable service discovery scheme that assures certain level of quality of service. The proposed model uses routing clients which communicate with Ser...

Automatic service discovery is essential for the usability of self-configuring Mobile Ad Hoc Networks (MANETs). Existing service discovery solutions are either directory based or directory-less. The directory based approaches are fast and reliable but have the complexity of maintaining directories in the dynamic MANET environment. On the other hand, the directory-less approaches use broadcasts ...

Service Discovery is expected to become a crucial application of mobile ad hoc networks (MANETs). A number of existing service discovery protocols is mainly aimed at infrastructure-based and/or 1-hop ad hoc wireless networks. In this paper, we propose a novel mechanism using hierarchical grid architectures for service discovery in MANET. The geographic area of MANET is partitioned into 2D logic...

Web Service discovery and composition is one of the key objectives of Service Oriented Architecture (SOA) which provides a loosely-coupled environment and enables flexible assembly of existing web services. Service discovery plays a vital role in the overall process of the service discovery and composition. The Web Ontology Language for Services (OWL-S) has emerged as the de facto standard for ...

We provide a conceptual model for context aware Semantic Web Service (SWS) discovery, which can utilize realtime legacy data from external systems and support user contextbased service discovery and selection. This model offers advantages over current SWS technology which cannot be easily applied to different domains or be integrated with legacy systems. Using this conceptualization we propose ...

Service discovery plays an important role in mobile ad hoc networks (MANETs). The lack of central infrastructure, limited resources and high mobility make service discovery a challenging issue for this kind of network. This article proposes a new service discovery mechanism for discovering and advertising services integrated into the Optimized Link State Routing Protocol Version 2 (OLSRv2). In ...
