An underlying cloud computing feature, outsourcing of resources, makes the service-level agreement (SLA) a critical factor for quality of service (QoS), and many researchers have addressed the question of how an SLA can be evaluated. Lately, security SLAs have also received much attention to guarantee security in a user perspective and provide optimal and efficient security service in the secur...

Radio spectrum is a scarce and non-reproducible natural resource hence spectrum management policies play a vital role in ensuring the efficient use of spectrum. Optimum usage of radio resources will be done by sharing these resources among various radio services. Last two decade has seen a tremendous growth in Indian telecommunications because of effective policies launched by governing body an...

The goal of this paper is to identify and analyze Web 2.0 services and usage models appropriate for assisting the realization of Inclusive Universal Access (introduced by Derntl and Motschnig-Pitrik as an extension to Universal Access) particularly in cooperative learning and knowledge sharing environments. The analysis is backed by previous research and experience either at the authors’ or oth...

The proliferation of the Internet has revolutionized the way people work together for business. People located at remote places can collaborate across organizational and national boundaries. Although the Internet provides the basic connectivity, researchers all over the world are grappling with the problems of defining; designing and implementing web services that would help people collaborate ...

Data in real-time databases has to be logically and temporally consistent. The latter arises from the need to preserve the temporal validity of data items that reeect the state of the environment that is being controlled by the system. Some of the timing constraints on the transactions that process real-time data come from this need. These constraints, in turn, necessitate time-cognizant transa...

In Intelligent Transportation Systems new applications based on cooperative approach are being created. These applications are characterized by the real time reconstruction of the driver environment used in combination of on-board sensors and cooperative system information. In this paper, we propose a traffic modeling and 802.11p access categories mapping of three main ITS services: warning to ...

Web Services has emerged as a dominant paradigm for constructing and composing distributed business applications and enabling enterprise-wide interoperability. A critical factor to the overall utility of web services is a scalable, flexible and robust discover mechanism. This paper improves UDDI specification, thus it could guarantee usability of response and append grid-like monitoring informa...

Recent experiments in collaborative working have shown some technical limitations that delay the massive deployment of such applications. These limitations concern the support of a variable multimedia quality of service (QoS) that is often insufficient, multicast services badly adapted to the group requirements, and over all, the cooperative features of persons involved in a group work session ...

This paper presents a development and an evaluation of a mobile mashup generator system to compose mobile mashup applications and Tethered Web services on a mobile device (TeWS). With less programming efforts, our system and description language framework enables a rapid development, a reusability of working components and a delivery of new cooperative mobile mashup applications. Working compon...
