We implement a collision prevention system, called pSafety, which instantaneously informs pedestrians and drivers of the potential threatening accidents. Unlike other systems, pSafety alerts pedestrians of threatening vehicles coming from not only the line-of-sight, but also non-line-of-sight due to obstructions of the wall corner or other vehicles. pSafety collects GPS information from smartphones...
Video sharing traditionally is an upload-then-share process for users. Users upload videos to cloud servers expecting their friends to login and share from these data centers. Therefore, real-time sharing is not possible since prior to the transmission, the uploading requires reformatting and transcoding the video file. This is both energy and time consuming especially that the cloud server is long-distant...
Authentication and key exchange are fundamental techniques for enabling secure communication over mobile networks. In order to reduce implementation complexity and achieve computation efficiency, design issues for efficient and secure biometrics-based remote user authentication scheme have been extensively investigated by research community in these years. Recently, two biometrics-based authentication...
Cloud computing is expected to provide quick, agile, stable and reliable services. Existing Cloud computing network architecture is very complexity. In order to improve security, management and energy saving in cloud computing network, this article proposes a simplified cloud computing network architecture based on OpenFlow, Autonomic and Identifier Locator split technologies. This new network architecture...
When platform sharing digital ocean information is taken as new era's basic infrastructure of serving ocean information, ability of safeguarding social work and level of Existing ocean resource exploitation are and environment protection are upgraded awfully , at the same time, it also become an important research direction about digital ocean. In this paper, on the base of analyzing frame sharing...
To cope with rapidly increasing Internet usage nowadays, providing Internet services using multiple servers has become a necessity. To ensure sufficient service quality and server utilization at the same time, effective methods are needed to spread load among servers properly. Existing load balancing methods often assume servers are homogeneous and consider only one type of resource, such as CPU....
With the resurgence of virtualization technologies and the development of multi-core technologies, the combination of the two becomes a trend. Therefore, inter-VM communication becomes a key part in how to improve the performance of virtual machines (VMs) basing on multi-core platform. In this paper, we first analyze the characteristics of multi-core tasks and the properties of virtual machine environment,...
Grid Computing is an effective computing paradigm widely used in solving complex problems. There are a variety of existing grid middleware systems which support operation of grid infrastructures, including CNGrid GOS, EGEE gLite, Globus Toolkit, and OSG Condor etc. These grid infrastructures focus on encapsulating underlying computing and storage resources and providing necessary basic services such...
