Due to the increasing number of cloud applications, the amount of data in the cloud shows signs of growing faster than ever before. The nature of cloud computing requires cloud data processing systems that can handle huge volumes of data and have high performance. However, most cloud storage systems currently adopt a hash-like approach to retrieving data that only supports simple keyword-based enquiries,...
IoT and Internet technologies brought more opportunities for museums to interact with their visitors or potential visitors. Smart phone and Mobile APP is widely accepted and took ways to protect local culture. In this research, a museum APP investigation and a questionnaire survey are performed. We summarized the functions of existed museum APP and the demands of young people, and then give a museum...
JointCloud provides a large-scale, flexible, and elastic computing resource platform. Big data systems such as MapReduce and Spark are widely deployed on this platform for big data processing. How to choose a cloud platform in accordance with the need of customers is a problem. Current performance benchmarking suites can choose suitable cloud platforms for customers. However, they do not consider...
Due to the limited computing resources in mobile devices, it is desirable to offload the computation intensive and time sensitive tasks to the network edge. This paper aims at optimizing the total consumption cost incurred by the usage of the limited computational resources in mobile edge (e.g. small cell, access point, macro base station) while satisfying all the computational demands from each network...
To support the various services quickly and flexibly, intelligence and automation are the key characters for future network resource management. How to build a big data based Telco cloud resource management framework is very important currently, which can leverages the power of Network Function Virtualization (NFV) and enhances telecom operators' availability of service, efficiency of resource, and...
Recently, iBeacon is popular used in many fields to push notification to visitors or customers by smart phone APP installed beforehand. Local culture protection organization, such as museum, historic relics park, etc., has the task to disseminate local culture via new IT. iBeacon and smart phone APP, two hotspots research, can be used to push and illustrate local culture information. This research...
Network Function Virtualization (NFV) and Software Defined Network (SDN) technologies makes it possible for the Telco Operators to assign resource for virtual network functions (VNF) on demand. Provision and orchestration of physical and virtual resource is crucial for both Quality of Service (QoS) guarantee and cost management in cloud computing environment. Auto-scaling mechanism is essential in...
The 21st century is the information age, the society benefits from the rapid development of high-speed broadband Internet. Of course not only society benefits, but also more multifarious technology platform derived from it. It also produced a new computing model - cloud computing, which is particularly important. Cloud computing refers to that cloud computing can deploy corresponding resources according...
Education informatization is paid more attention to the development of web technologies recent years. Finding an effective way to make the best of existed public education resource distributed in different areas is an emergent task. Cloud computing technology is popular and utilized in many fields, and many facts show that it's a good way to resolve the bottlenecks of public education resources. In...
nfrastructure-as-a-service (IaaS) is one of several main styles of Cloud Computing, in which virtualized computing resources are managed as a pool and provisioned on demand. When virtual machines are provisioned, a big amount of time is spent on image transfer from central image repository to target nodes. In this paper, we present an image cache mechanism, which can greatly reduce the provision time...
