One of the main obstacles to the adoption of Wireless Sensor Networks (WSNs) outside the research community is the lack of high level mechanisms to easily program them. This problem affects distributed applications in general, and it has been replied by the Software Engineering community, which recently embraced Service Oriented Programming (SOP) as a powerful abstraction to ease development of...

Page 1 of 6 Weapons of Mass Disruption: Denial-of-Service Attacks Ronnie Johnson September 2009 Introduction The Internet is an open communication medium whose communications protocols were not designed to be security conscious, exposing the Internet to attack by anyone with basic computer skills. There are numerous threats on the Internet; however, this paper will focus on a particular attack ...

This paper presents a pair of role-based access control models for workflow systems, collectively known as the W-RBAC models. The first of these models, W0-RBAC is based on a framework that couples a powerful RBAC-based permission service and a workflow component with clear separation of concerns for ease of administration of authorizations. The permission service is the focus of the work, prov...

This paper describes the design and implementation of MOBY, a network for mobile peer-to-peer exchange of services and data. Constraints on computing power of mobile devices, limited hardware, networking, and software resources, and ad-hoc nature of mobile clients pose considerable challenges from the points of view of supporting performance goals, ease of service integration, and adaptation. T...

With the rapid usage rate of mobile phone and advances in healthcare technology, as well as current concerns arise over public’s health, mobile health are attracting the attention of more and more people. Although previous studies on the adoption of mobile services are quite extensive, few focus on public users’ adoption of mobile health service (MHS). In this study, we examine the determinants...

Digital services can be thought as internet based applications that fulfil users’ needs and their quality represents a basic element during the delivery process. In such a context, usability is one the main quality parameters and it refers to the ease of benefiting from the functionalities and the information the service provides. We propose a list of quality parameters and a formal model suita...

Success in online services cannot promise the success in corresponding mobile services. To understand the mobile service adoption behavior under the context of online service transition, this study, taking mobile payment as an example, from a trust transfer perspective, examines users’ acceptance of mobile payment using the TAM (Technology acceptance model). A field survey with 220 mobile payme...

Multimedia multiparty applications on the Internet are commonly supported by specific servers containing all the required functionalities in a centralized manner. The IP Multimedia Subsystem (IMS) is the current paradigm of the Next Generation Network (NGN) model. It provides a set of basic service enablers and functions beyond IP connectivity, such as multimedia session control, presence and g...
