Context Model Based on Ontology in Mobile Cloud Computing

Abstract

Abstract. Mobile Cloud Computing has become as a new IT paradigm because of the growth of mobile device like smartphone and appearance of Cloud Computing environment. This mobile cloud environment provides various services and IT resources according to users' requests, so an effective management of service and IT resources is required. Hence, this paper designs a context model based on ontology in mobile cloud computing in order to provide distributed IT resources and services to users based on context-awareness information. As the context model proposed in this paper uses context-aware information, it enables to provide more accurate personalized services and manage distributed IT resources.

Towards Intelligent Distributed Computing: Cell-Oriented Computing

“…It has rapidly modified the information technology scene and eventually made the goals of utility computing into a reality [15]. In order to provide distributed IT resources and services to users based on contextaware information, Jang et al designed a context model based on the ontology of mobile cloud computing [16]. In the same area of smart cloud research, Haase et al [17] discussed intelligent information management in enterprise clouds and introduced eCloudManager ontology in order to describe concepts and relationships in enterprise cloud management .…”

Efficient Security Method Using Mobile Virtualization Technology And Trustzone of ARM

“…Mobile virtualization technology has been used across many different embedded systems. Its technology has been represented by a very thin software abstraction layer called virtual machine monitor (VMM) or hypervisor [1,2,6,7]. A common platform comprises hardware, operating system, and user applications in the vertical order.…”

“…The domain isolation is valuable for security and reliability of the software systems. The reason VMMs hold great potential for security is that they can play an important role in creating separate domains in a physically single machine [1,2].…”

“…Recently, mobile virtualization techniques have been used for reinforcing the system security and reliability because they provide isolated domains on which various systems with different security policies reside simultaneously [1,2,11]. Several studies are effective virtualization to analyze malicious code or to prevent mobile device from trying hacking.…”

“…But today's mobile security solution is simply to detect malicious code or stay on the level of mobile device management. In order to overcome these limitations of mobile security and the problems, it is needed that mobile virtualization-based security technology which fuses mobile security technologies with virtualization technology, can be run on a variety of mobile devices, and can be operated on the latest Android and Linux operating system for smartwork environment [1,2,3,4].…”
