The maintenance and management for the current Fourth Generation (4G) networks are still in a manual and semi-automatic manner, which are costly and time-consuming. This imposes a great challenge on the network management of heterogeneous, software-defined and virtualized Fifth Generation (5G) systems. With the advent of network intelligence, a possibility on intelligent management is opened for the...
To address the explosively growing demand for mobile data services in the 5th generation (5G) mobile communication system, it is important to develop efficient content caching and distribution techniques, aiming at significantly reducing redundant data transmissions and improving content delivery efficiency. In heterogeneous cellular network (HetNet), which has been deemed as a promising architectural...
Vehicular Ad-hoc Networks (VANETs) are formed by a huge number of vehicles which act as the network nodes and communicate with one another. This emerging paradigm has opened up new business opportunities and enables numerous applications ranging from road safety enhancement to mobile entertainment. A fundamental issue that impacts the successful deployment of VANET applications is the security and...
This stage manage system is designed specifically for the integrated-control console of visual-effect equipment. System architecture, functional implementation and technical solution are proposed detailedly in this paper. This system is established based on C/S framework. Data transmission between the stage management console of visual-effect equipment and the integrated-control system is implemented...
We describe in this paper the advantages of HTML5 local storage, and introduce the application of HTML 5 local storage technology in the system. As a new kind channel and service mode of cultural communication, the service system of theater 3D model can display the 3D information of theater. There will be data load repeated when the customer opens the system again. In order to reduce the redundancy...
Node.js is one of the better-known frameworks and environments that support server-side JavaScript development. Many frameworks provide a full-featured Web stack, such as Connect and Express. Finally, many libraries available for client-side JavaScript that were written to comply with the Common JS module system also work with Node. In my work, we leverage node.js platform to construct a 3D theatre...
Hybrid streaming delivery over converged mobile and broadcast networks can enable operators to transmit multimedia contents in a more efficient and flexible way. Consequently, the functions related to hybrid streaming delivery are recently standardized in the IP-based service layer standards for DVB-H, i.e. DVB-IPDC and OMA BCAST standards. In both standards, seamless service switching is one of the...
Over the last 2-3 years, the importance of data-intensive computing has increasingly been recognized, closely coupled with the emergence and popularity of map-reduce for developing this class of applications. Besides programmability and ease of parallelization, fault tolerance is clearly important for data-intensive applications, because of their long running nature, and because of the potential for...
Botnet is a hybrid of previous threats integrated with a command and control system and hundreds of millions of computers are infected. Although botnets are widespread development, the research and solutions for botnets are not mature. In this paper, we present an overview of research on botnets. We discuss in detail the botnet and related research including infection mechanism, botnet malicious behavior,...
A critical component of today's commercial search engines is an advertisement platform. The current state-of-the-art of such platforms is primarily based on advanced keyword matching to determine the relevance of advertisements for users' queries. However, such keyword matching techniques suffer from missing user intent when the query domain is visual as opposed to textual. To handle such a domain,...
In this demonstration, we present VisiAds, a vision-based online advertising platform which allows advertisers to bid on image content as opposed to text keywords. The demonstration shows an implementation of the platform designed specifically for mobile application scenarios. It can be used by advertisers to trigger and deliver multiple advertisements based on a query image captured from a consumer-grade...
For assessing the security and optimal strengthening of large enterprise networks, this paper proposes a new approach uses configuration information on firewalls and vulnerability information on all network devices to build defense graphs that show the attack and defense strategy. Some models including a defense graph model, attack-defense taxonomy and cost quantitative model, and Attack-Defense Game...
Energy consumption and timely requirements are two key factors affecting the performance of mission-critical cyber-physical systems. Little work deals with scheduling a set of time-sensitive services in a finite time interval. We consider a server serving N users in time interval [0, T]. Each user demands its service to be completed in a strict deadline. Based on convex power-speed relationship, a...
