Service discovery is one of most challenging issues now-a-days because of the increasing number of services but a very few techniques are available for their efficient discovery. It is worthless if there are abundant services available but we cannot avail our desired services only because of the irrelevant discovery system. The semantic based service discovery is proposed to enhance the discove...

Emerging service-oriented architectures are pushing towards on-demand and ‘‘on the fly’’ composition of applications and business processes. In order to support service composition, the underlying infrastructure must provide a facility for on-demand discovery of services and service components. Discovery becomes challenging when services span heterogenous and independently administrated domains...

The ability to locate useful on-line Web Services is becoming critical for today’s service-oriented business applications. A number of efforts have been put to enhance the service discovery process by using conceptualised knowledge, called ontology, of particular service domains to describe service characteristics. This paper presents an ontology-based approach to enhance descriptions of Web Se...

Various approaches in service engineering are based on service markets where brokers use service matching in order to perform service discovery. For matching, a broker translates the specifications of providers’ services and requesters’ requirements into her own specification language, in order to check their compliance using a matcher. The broker’s success depends on the configuration of her l...

This paper presents a research initiative, which aims at developing replication mechanisms for the dynamic management of the content of several Universal Description, Discovery, and Integration (UDDI) registries (Curbera et al., 2003). These replication mechanisms are intended to be deployed in an environment of Web services (Papazoglou & Georgakopoulos, 2003). By content of an UDDI registry, w...

Advent of mobile and wireless computing has changed traditional way of computing and communication based on wired networks. Users in mobile environment expect the same computing luxury which they used to enjoy in fixed computing environment. With a plethora of wireless hardware and software services present, the challenge is to determine how best we can utilize them. Service Discovery aims to s...

In an expected future multiaccess and multiservice IEEE 802.11 environment, the problem of providing users with useful servicerelated information to support a correct rapid network selection is expected to become a very important issue. A feasible shortterm 802.11-tailored working solution, compliant with existing equipment, is to publish service information encoded within the SSID information ...

This paper proposes a market-place based architecture, where users can detect wireless network services, negotiate with the identified service providers about price and service features, select the best service, and finally configure their devices according to the selected service. The architecture automates these different steps by the use of agents that represent the involved entities such as...

Service discovery over the Web is considered a crucial issue; in particular, flexibility of the discovery process, that is, the ability of recognizing not only exact matches between the requests and offers, but also partial ones, needs to be enhanced. We have defined a composite approach to flexible service matchmaking with different matching models. In this paper we present the novel differenc...
