New generations of cloud applications are increasingly complex and pose lower latency requirements. e la er is forcing the industry to reduce network latency by adding computation nodes near the edge of the network, also known as Fog Computing. To utilize the Fog nodes efficiently, the dynamic placement and migration of application components must be supported. To this end, a Fog- aware application...
Ambient intelligent services often need to be executed at computing devices whose computational resources are limited. To solve this problem, such services intensive tasks should be offloaded to cloud computing. However, there is a gap between access control models in ambient intelligent services and cloud computing, where the former tends to be context-dependent and the latter to be subject-based,...
Offloading context-aware services with intensive tasks to cloudcomputing infrastructures is useful. However, we have a problemresulting from differences between context-centric access controlmodels for pervasive computing and subject-based access control modelsfor cloud computing. To solve this problem, this paper proposes alocation model for spatially specifying containment relationships ofpersons,...
Existing research on implementing the mobile cloud computing paradigm is typically based on offloading demanding computation from mobile devices to cloud-based servers. A continuous, high quality connection to the cloud infrastructure is normally required, with frequent high-volume data transfer, which can have a detrimental impact on the user experience of the application or service. In this paper,...
Mobile Cloud Computing has been worldwide accepted as a concept that can significantly improve the user experience when accessing mobile services. Mobile applications have become more popular all across the world. By removing the limitations of mobile devices with respect to storage and computing capabilities and providing new integrated levels of security by centralized maintenance of security-critical...
The exponential increase in the number and types of mobile devices, along with their ever-growing sets of capabilities, have enabled the development of new architectures that aim to harness such heterogeneity. Transient Clouds (TCs) are examples of mobile clouds which are created on-the-fly by the devices present in an environment to share their physical resources (e.g., CPU, memory, network) and...
The Internet of Things (IoT) has given rise to new types of data, emerging for instance from the collection of sensor data and the control of actuators. The explosion of devices that have automated and perhaps improved the lives of all of us has generated a huge mass of information that will continue to grow exponentially. For this reason the need to store, manage, and treat the ever increasing amounts...
The increasing penetration rate of feature rich mobile devices such as smartphones and tablets in the global population has resulted in a large number of applications and services being created or modified to support mobile devices. Mobile cloud computing is a proposed paradigm to address the resource scarcity of mobile devices in the face of demand for more computing intensive tasks. Several approaches...
With the rapid development of mobile cloud computing, the identity authentication has become more and more important. but most of the authentication methods were authenticating device rather than users. Context aware information, such as, operational context, personal context, spatial context, and environmental context, can provide users with their really needed services without any explicit requests...
Contextual information are used to describe situations of entities (users and devices) and their interactions. Applications need such information in order to adapt their behaviour in response to changes in the entities context. In certain scenarios and in particular machine to machine, the integration of a large number of components makes the management of the generated contextual information a very...
Context-aware systems offer entirely new opportunities for application developers and for end users by gathering context data and adapting systems' behavior accordingly. In this paper, we propose a Context Aware ESB (CA-ESB) that will publish and discover services based on location context. The main modules of the framework consist of Context Provider (senses location context), Context Aware Logic...
The existing reminder system uses limited context information and has limited functions, so it can't meet users ' needs. This paper presents intelligent business assistant based on context-aware computing platform in a grid computing environment. The platform uses the context modeling and reasoning technology and analyzes the system in the grid environment. At last, the intelligent business assistant...
We consider geographically distributed data centers forming a collectively managed cloud computing system, hosting multiple Service Oriented Architecture (SOA) based context aware applications, each subject to Service Level Agreements (SLA). The Service Level Agreements for each context aware application require the response time of a certain percentile of the input requests to be less than a specified...
Traditional Learning Management Systems (LMS) failed in providing pervasive and personal services since lacking flexibility and adaptivity. This paper addresses the problems in existing LMSs and reviews related technologies in improving interoperability, reusability, flexibility and cost efficiency, followed by proposing a new framework design using service-Oriented architecture.
We observe two of the recent trends in information technology. Cloud Computing (CC) is widely accepted as an effective reuse paradigm. Mobile Computing with Mobile Internet Device (MID) such as iPhones and Android devices becomes a convenient alternative to personal computers by integrating mobility, communication, software functionality, and entertainment. Due to the resource limitations of MIDs,...
