Cloud Computing, with its on-demand provisioning capability on shared resources, has emerged as a new paradigm for reducing IT costs. In this paper, we present the architecture of a provisioning system that simplifies the deployment of complex application services on a Cloud infrastructure. We will introduce the concept of Composite Appliance and explain how it can be implemented and utilized to simplify...
For several years the mantra has been “closing the Business - IT gap”, enabling business people to focus on strategic direction, while not being unnecessarily burdened by the complexity of the underlying support systems. The discipline of Business Architecture continues to evolve, attempting to bring rigor to the task of matching imprecise strategic needs to rigid IT systems. Increasingly literature...
Privacy preserving in location-based service (LBS) has been an important issue in Vehicular Ad hoc Network (VANET). Traditional k-anonymity algorithm dealing with location privacy protecting problem does not consider vehicle's mobility and inner collaborator. In this paper, we propose a new algorithm which uses dynamic and mobile aware anonymous peer selecting algorithm to improve the anonymity and...
This paper first presents a RFID-based mobile logistics monitoring system framework composed of mobile front-end application sub-system and back-end monitoring and service sub-system. The system architecture is designed, and the operating principle is described. The architectures and functions of the front-end application software and back-end monitoring software are discussed in detail. In practical...
Service-Oriented Architecture (SOA) provides a flexible architecture for service composition. Service composition can be integrated by atomic Web services developed independently by their providers. With increasing number of alternative services that implement similar functionality but provide different non-functional (QoS) characteristics, service composition becomes a service selection problem....
A mobile device such as Android device is emerging as a convenient client computing device with mobility and context-sensing capability. However, the computing power and hardware resource of the devices are limited due to the small form-factor. Consequently, large-scaled applications could not be deployed on these devices. To remedy the limitations, it is desirable to deploy some heavy-weight functionality...
Machine persistent connections. Evolving towards mobile and wireless pervasive networks, Internet has to entertain dynamic, transient, and changing interconnections. The vision of the Internet of Things furthers technology development by creating interactive environment where smart objects are connected and can sense and react to the environment. The resulted event flooding in such IOT environment...
Location-Aware computing is one important field in ubiquitous computing. Location-Aware applications play an important role in many fields, especially mobile systems and navigation systems. Additionally, the new Internet of Things depends deeply on technologies in Location-Aware Computing. Based on our survey, it is difficult to locate accurately with GPS in a building because of positions in different...
As a typical form of Cloud service, Software as a Service(SaaS) has been leading the adoption of Cloud to enable e-Business by the industries. There are growing number of SaaS services which could provide different aspects of capability enabling business to leverage Cloud platform to run and manage business processes, such as customer relationship management, supply chain management, finance and accounting...
Cloud computing often uses the multi-tenancy architecture where tenants share system software. To support dynamically increasing demands from multi-tenants, the cloud service providers have to duplicate computing resources to cope with the fluctuation of requests from tenants. This is currently handled by virtualization and duplication at the application level in the existing cloud environment, such...
