With the popularity of mobile Internet and the rapid development of data mining, we can collect users' behavior trajectory and find regularity from a large amount of data. In this paper, we use the WiCloud system to obtain students' trajectory information, and propose a spatial-temporal clustering method based on K-means algorithm, which clusters students into three types: study-oriented, enclosed...
Information and Communication Technology is always walking in the forefront of human education. Now, it is the stage where human education has to adapt itself to the developing technologies. In 2016, the Natural Science Foundation suggested that people need to use the human-technology to improve and extend the human learning. This paper provides the concept of Software Defined Class (SDC), where the...
A smart campus refers to a campus where modern information and communication technologies bring more convenience to campus life, assist campus users to improve and more efficiently accomplish their daily activities, and enhance social interactions. Regarding the high demand of services such as mining campus users' semantic information, building augmented reality assisted mobile campus and smart class,...
With the rapid development of mobile Internet, the ways in which users access the network become diverse, which provides much convenience for us to collect huge amount of users' behavior information. In this paper, we combine data acquisition based on wireless access and brand analysis innovatively. This paper analyzes proportions of mobile terminal brands on campus using the data collected from WiCloud...
Routing problems find applications in many location-based services. Existing works which answer route queries mainly focus on static road networks rather than time-aware road networks. Observe the fact that (i) the same road segment may be driven with different speeds during different time intervals, and (ii) users usually prefer driving on a route that consumes minimum energy within a travel time...
As a promising technology for the future Internet, network virtualization makes it possible to reshape currently ossified network architecture. This paper proposes a limited scale-free model for construction of virtual networks topologies, aiming to reduce network average path length and achieve a simplified virtual network. In the progress of constructing, new links are added into the initial network...
Compared with the traditional stiff and decentralized security mechanisms, software-defined security SDS provides a flexible and centralized solution through extract security strategy from the hardware to the software. A variety of software-defined security architecture has been proposed, basically like SDN three layer, let the control layer separate from the data layer. Now, however, these software-defined...
Software-defined Networking, known as SDN, is a novel architecture that decouples the control plane from the data plane, and opens a programmable network. However, it is common practice for network operators to divide the large-scale networks into multiple domains and manage the networks by using a group of controllers. Designing a scalable SDN control plane becomes a critical problem. In this paper,...
Mobile Edge Computing (MEC) provides mobile and cloud computing capabilities within the access network. Network Functions Virtualization (NFV) leverages standard IT Virtualization technology to decouple the network functions from the underlying physical infrastructure. Basing on the ICT demand, MEC can be consolidated into NFV, as a network element within access network. This paper presents an architecture...
Mobile Edge Computing (MEC) aims to provide mobile and cloud computing capabilities within the radio access network, and emphasizes the openness of the internet which can transfer the real-time radio network information into context-related services. In this article, we research the state-of-the-art technology of mobile and cloud convergence, then propose WiCloud, a MEC platform, which integrates...
With the rapid development of mobile Internet, the way users access the network becomes diverse, which provide much convenience for us to collect huge amount of users' information. In this paper, we present a model of measuring relationship between two users in campus and build a wireless data analysis system called WiCloud to verify our model. This work has several potential applications such as...
In the last two years, ETSI's NFV Management and Orchestration working group has defined the NFV reference architecture. Network Function Virtualization (NFV) intends to decouple the network function from dedicated network appliance through virtualization technologies. As security is an important issue in the context of NFV environments, but the ETSI NFV architecture didn't involve much about security...
Mobile Edge Computing (MEC) provides mobile and cloud computing capabilities within the access network, and aims to unite the telco and IT at the mobile network edge. This paper presents an investigation on the progress of MEC, and proposes a platform, named WiCloud, to provide edge networking, proximate computing and data acquisition for innovative services. Furthermore, the open challenges that...
With the popularity of wireless networks and the prevalence of personal mobile computing devices, understanding the mobility of users in wireless network is of great significance to the social network analysis. As the usage of computing and communication devices reflects their social connectivity with others, We design a new data collection way which based on wireless detection, and according to the...
Human detection and tracking is a key and fundamental problem of smart devices and intelligence applications. Currently, video surveillance and infrared image surveillance are the mainstream solutions of this problem, however suffering from multiple complex difficulties. Meanwhile, the high penetration rate of Wi-Fi equipment and smart phones and mature technology of Wi-Fi positioning make it possible...
In order to study the distribution law of human mobility time attribute and identify the individual identity according to the law, six months real data is collected in different scenarios through the Wireless-Data-Collection-Analysis-System developed by our laboratory. On the basis of AIC, we analyze the time distribution from the perspectives of wireless hotspot group users and individual users respectively...
This article aims at controlling Optical Networks in software method based on OpenFlow Extension. We abstract OTN equipment on Layer Class and combine it with OpenFlow to achieve unified management of data and optical plane.
This paper describes the work done to test the interoperability of northbound interface implemented in the controllers of a transport SDON prototype. A test framework named NBI Platform is introduced and used in this test.
With the development of Mobile Internet and the rapid growth of mobile social communication and mobile video, the network scale has been growing rapidly and the energy consumption is too huge to be ignored. Current estimates indicate that Information and Communication Technology (ICT) is responsible for a fraction of the global energy consumption ranging between 1% and 2%, among which, the consumption...
Software Defined Network (SDN) is an emerging architecture which can simplify network management and enable innovation through network programmability by decoupling the control plan and the data plan of the network. However, traditional SDN architecture is not suitable for all cases; a single controller may become a performance bottleneck in a wide area network. While current multiple controller solutions...
