Service Oriented Architecture (SOA) is an approach to build distributed systems that deliver application functionality as services are language and platform-independent. Web service one of the fundamental technologies in implementing SOA based applications. modular, self-describing, self-contained loosely coupled applications can be published, located, invoked across web. As number web increase...

Web Service Discovery can be described using OWL-S. It follows web service discovery model because it has conceptual and trivial semantic web service descriptions using service profile ontology of OWL-S. The Web Service Discovery model uses Web Service matchmaking algorithm which enlarges matching techniques used in Structural Case Based Reasoning, allowing the retrieval of Web services based o...

Dynamic service discovery and late binding to the most appropriate network service will be the key characteristics of future adhoc networks. In adhoc networks, the nodes are mobile and the multihop environment does not rely on an existing communication infrastructure. Mobile nodes dynamically establish routes among themselves to form a network “on the fly”. “Appropriateness” of a service is a s...

Success of Web services mainly depends on the availability of tools facilitating usage of technology within the addressed B2B integration problems. One severe problem in loosely coupled systems is service discovery including a sufficient matchmaking definition. The concept for service discovery in web service architecture is UDDI providing limited querying functionality and not being capable to...

Service discovery is a crucial feature for the usability of mobile ad-hoc networks (MANETs). In this paper, Minimum Dominating Forward Node Set based Service Discovery Protocol (MDFNSSDP) is proposed. MDFNSSDP has the following characteristics: 1)It minimizes the number of coverage demanding nodes in the current node’s 2-hop neighbor set. 2) It minimizes the size of dominating forward node set ...

The research of Web service discovery can be distinguished into two layers: service discovery model and service discovery algorithm. In this paper a kind of services discovery model named WSDBC (Web Service Discovery based on BalanceChord) is proposed in order to extend the Web services discovery scope and improve discovery efficiency. In order to achieve load balancing between different nodes ...

AbstrAct Web services form the core of e-business and hence, have experienced a rapid development in the past few years. This has led to a demand for a discovery mechanism for Web services. Discovery is the most important task in the Web service model because Web services are useless if they cannot be discovered. A large number of Web service discovery systems have been developed. Universal Des...

A two-step indexing based method which indexes services by their ontologies is proposed for efficient and quick semantic service discovery. In first step, for a given service request, a set of candidate services are chosen from the index by matching the ontologies of the request with the keys of index. In the second step, the request is semantically matched with candidate services ranked by the...
