--Cloud computing makes highly scalable services to be used over Internet on as per need basis. In cloud the user data is processed remotely on unknown machines. Cloud computing has some risks for both the customer and the cloud provider. Usually cloud computing services are offered by a third party provider who owns the infrastructure. It moves the application software (services) and databases...

The Internet provides tremendous flexibility, in that it can support a wide variety of services, and accessibility, in that these services can be invoked from anywhere. However, the current Internet architecture does not easily support service portability. If users want their service names to be persistent then they must stick with the same service provider because service names, such as email ...

Recent studies show that much of Electronic Commerce activities will be conducted via the Internet, such activities encompassing business-business as well as client-business and administration-business relationships. However, the Internet has not been designed to support such activities and it lacks many features, as Quality of Service requirements or Charging and Accounting facilities. At the ...

The Internet today offers primarily a best-effort service. Research and technology development efforts are currently underway to allow provisioning of better than besteffort Quality of Service (QoS) assurances. In this article, we develop a spot pricing framework for intradomain expected bandwidth contracts with loss based QoS guarantees. The framework builds on a nonlinear pricing scheme for c...

The paper proposes a new method for the analysis and evaluation of the Quality of Service (QoS) in a mobile Internet access scenario. In particular, the paper proposes a throughput evaluation method based on PathChirp algorithm. The end-to-end bandwidth was estimated by means of the Self Loading of Periodic Streams (SloPS) technique. The obtained measurements were then analyzed by estimating th...

An Electronic-Service (E-Service) can be defined as a collection of network-resident software programs that collaborate for supporting users in both accessing and selecting data and services of their interest present in a provider site. Examples of eservices are e-commerce, e-learning, e-government, e-recruitment and e-health applications. E-Services are undoubtely one of the engines presently ...

To access services on the Web, users need quite often to have accounts, i.e. user names and passwords. This becomes a problem when the number of accounts keeps increasing at the same time password is a very weak form of authentication exposing the users to fraud and abuses. To address both mentioned issues we propose a Mobile Universal identity, which by combining Internet identifiers with mobi...

Countries around the globe have an ageing population that faces problems such as cognition, memory and visual difficulties. Mobile devices and products are part of daily life and to utilise them the role of internet service providers is essential. This research-in-progress paper aims to identify and evaluate factors that influence the older population’s (over 50 years) selection of an internet ...
