In recent years, diverse solutions for service discovery in mobile ad hoc networks have been proposed. These solutions basically follow two approaches: the first one considers routing and service discovery as separate activities (i.e. implementing independent protocols for each activity); the second one integrates routing and service discovery into a single protocol. Based on this second approa...

Nowadays, portable electronic devices allow users to access available resources wherever they are. In this sense, announcement and discovering of services and resources are two central problems to be solved in ubiquitous computing. Despite the fact that many service and resource discovery protocols exist, they are limited to a concrete network technology and most of them do not face mobility an...

In this work we present a service discovery system that supports flexible queries using partial keywords and wildcards. It is built upon a Chord network and it guarantees that any existing data that match a query is found. The main feature of this service is to use a proxy server layer with a mechanism for data distribution that reduces the number of nodes involved in the searching process.

In this position paper we propose a framework for proactive SLA negotiation that integrates this process with dynamic service discovery and, hence, can provide integrated runtime support for both these key activities which are necessary in order to achieve the runtime operation of service based systems with minimised interruptions. More specifically, our framework discovers candidate constituen...

Decentralized systems have emerged as an alternative to centralized approaches for dealing with dynamic requirements in new business models. These systems should provide mechanisms that contribute to flexibility and facilitate adaptation to changes in the environment. In this paper, we present two self-organization mechanisms for a decentralized service discovery system in order to improve its ...

Selected service-discovery systems allow clients to issue multicast queries to locate network devices and services. Qualifying devices and services respond directly to clients; thus, in a large network, potential exists for responses to implode on a client, overrunning available resources. To limit implosion, one service-discovery system, UPnP, permits clients to include a jitter bound in multi...

The semantic Web service discovery has been given massive attention within the last few years. With the increasing number of Web services available on the web, looking for a particular service has become very difficult, especially with the evolution of the clients’ needs. In this context, various approaches to discover semantic Web services have been proposed. In this paper, we compare these ap...

The past few years have seen the Grid is evolving as a service-oriented computing infrastructure. It is envisioned that various resources in a future Grid environment will be exposed as services. Service discovery becomes an issue of vital importance for utilising Grid facilities. This paper presents RSSM, a Rough Sets based service matchmaking algorithm for service discovery that can deal with...

With the advent of service oriented architecture, Web services have gained tremendous popularity. This warrants the need to establish an effective and reliable process of Web service discovery. This paper presents a novel approach to enhance the accuracy of Web service discovery by finding semantically similar Web services for a user query using the support-based latent semantic kernel. The emp...
