Service discovery studies in vehicular networks that guarantee QoS requirements to service requesters are very important. To the best of authors’ knowledge, none of the existing service discovery protocols in vehicular networks have been provided in the literature that guarantee QoS to service requesters and to the vehicular network. For efficient service discovery in vehicular networks, it is ...

Mobile devices are inherently scarce in resources, necessitating the need to cooperate among them for performing tasks that cannot be done alone. This cooperation is in the form of services that are offered by other devices in the network. To get benefit from the services offered by other devices, they have to be discovered. Service Discovery Protocols (SDPs) are used for this purpose. This is ...

Service discovery enables users to access information, resources and services anytime, anywhere. This involves a client, a service provider and an infrastructure for service registration and lookup. Clients use service discovery protocols (SDPs) to issue a service request to a service registry or an individual service provider. In this paper we investigate the suitability of existing SDPs for m...

This report presents the specification of the Unified Service Query Language (USQL), which is aimed at supporting the discovery of heterogeneous Web, Peer-to-Peer, and Grid services. At the conceptual level, USQL establishes an abstract and service type-independent viewpoint of the service properties, which are constrained by service requesters through their search criteria. At the grounding le...

Web services are the new paradigm for distributed computing. A critical factor to the overall utility of Web services is a scalable, flexible and robust discovery mechanism. Traditional centralized indexing scheme can’t scale well with a large distributed system. In this paper, we first use an ontology-based approach to capture real world knowledge for semantic service annotation. Then we use a...

Web services provide a standard means for the interoperable operations between electronic devices in a network. The mission of Web service discovery is to seek an appropriate Web service for a service requester on the basis of the service descriptions in Web service advertisements and the service requester’s requirements. Nevertheless, the standard language used for encoding service description...

Discovery of services and other named resources is expected to be a crucial feature for the usability of mobile ad-hoc networks (MANETs). Different types of service discovery architectures are distinguished by the extent to which Service Coordinators (SCs) are implemented in the network. SCs are nodes that hold a central repository for the caching of service attributes and bindings of servers l...
