Our life is becoming faster day by day by the blessing of the internet of things (IoT). It plays a vital role to reduce the time to complete a computer-based or IT related work. Cloud and fog computing are one of the main elements of IoT which helps to provide service accurately in fewer times. A significant portion of the work related to fog and cloud computing indicates that fog computing is better...
Cloud architectures have become increasing common in the IT industry and academic circle. However, most cloud architectures only focus on availability but ignore economic effectiveness. Based on Eucalyptus, this paper proposes an effective way to balance high availability and economic profits. We designed a forecast mechanism using three new modules: the forecast module, adjustment module, and collection...
Challenges in bioinformatics include tools to treat large-scale processing, mainly due to the large volumes of data generated by high-throughput sequencing machines. Besides, many of these tools are not user friendly, and do not distribute their workloads properly. In federated cloud environments, even though services and resources are shared and available online, the processes of a workflow execution...
This paper introduces a new trust management system (TMS) for the cloud computing domain. The wide majority of these systems do not fulfill the requirements of today's cloud environments which are characterized by heterogeneity in providers, capabilities and users. As such, they are limited to few aspects of trust. In fact, they are bound to a single function or a direct interaction with the cloud...
Traditional models of computing with wireless sensors imposes restrictions on how efficiently wireless sensors can be used due to resource constraints. Newer models for interacting with wireless sensors such as the Internet of Things and Sensor Cloud aim to overcome these restrictions. This tutorial will discuss a sensor cloud architecture that enables different wireless sensor networks, spread in...
For notification distribution, we have designed and implemented a mobile device management system called Meta XA. Meta XA is based on an event-driven architecture combined with the complex event processing technology. In this paper, we propose an approach to bringing Meta XA into the cloud computing domain, without having to change its architecture.
Although migrating library applications to Cloud environment is not an easy task, many libraries are interested in using Cloud infrastructure services broadly across their businesses, whether is about a Public, Private or Hybrid Cloud. One of the migration expectations is the scalability of digital preservation architectures in Cloud environments. In this paper we address the scalability and portability...
The paper introduces the basal principles of Vector Space Model, the architecture of Hbase cluster, and relational conceptions, makes a science and technology dissertation retrieval system based on cloud computing technology, and gives steps of realization. The application experiment shows it can deal with search requests rapidly, advances a little precision ratio, and has effective application value.
We propose a new structuring mechanism and architecture for construction of overlay networks spanning multiple clouds. We have designed and implemented Suorgi for this purpose, a run-time that supports extensibility of cloud infrastructures. Novice users can now construct their private cloud overlay networks without explicit programming knowledge. Key to support this is meta-code, preprogrammed code...
With the development of 3G mobile technology, the mobile learning (M-Learning) platform research becomes the demand of the Times. Based on cloud service for convenient hardware resource allocation and ontology for good individual learning, the system architecture of mobile learning platform is proposed and some key techniques are studied in this paper. Finally, a kind of M-learning platform framework...
