This paper presents a design and implementation method of living streaming system based on multi-service nodes collaboration. The system uses the entropy weighting method to dynamically determine the weight factor of each service node and uses the coordinator node to collect the load information of service nodes and perform global optimal distribution of loads. The collection terminal uses RTMP (Real...
This paper proposes a framework of change detection with multi-source remote sensing images through collaboration of multiple operators. Firstly, pre-processed images are distributed to different operators. Then the images are classified by the operators independently. Finally, with uploaded classification results, change detection result can be derived through evidential fusion based on PCR5 rule...
With the development of information technology, a growing number of users begin to use Internet as a platform to plan their itinerary collaboratively. During the online itinerary planning process, collaboration plays an increasingly significant role. As the number of users grows, it is challenging to support more and more participants to plan itineraries online collaboratively, due to the requirement...
This paper uses retrieval technology to create a video content analysis system for collaborative film production. Present film production handles all contents as digital files and demands the collaboration of remote locations. This process requires contents transfer among locations and also collaboration tools like comment-based communication. For more creative collaboration, automatic content analysis...
The prediction of online video session progress is useful for both optimizing and personalizing end-user experience. Our approach for online video recommendation is to use the session progress information instead of using a traditional rating system. We approach the prediction of session progress as a matrix completion problem, and complete the session progress matrix using noisy low-rank matrix completion...
Content Centric Networking (CCN) is a new emerging network architecture, shifting from an end-to-end connection to a content-centric communication model. A number of content-oriented characteristics, such as name-based routing, arbitrary topology and ubiquitous caching make caching in CCN different from the previous works. In this paper, we focus on the collaborative caching in CCN and propose a dominating-set-based...
Named Data Networking [1] has an intrinsic distributed nature, which eases decentralizing formerly centralized protocols as discussed in [12], [10]. Nevertheless, implementing fully distributed protocols for many-to-many communications remains challenging. The NDN architecture, built upon CCN [3], makes the following assumptions in order to place content as the narrow waist of the communication stack:...
Based on the in-depth research of the P2P technology, we propose an implementation scheme of the P2P communication system for the wireless network environment, design a new hybrid structure model and describe the query mechanism, which can be used in the two-level domain of the distribution structure, in addition, we also design the P2P transmission protocols, which are quite fit for the wireless...
We propose a novel collaborative caching framework to support spatial query processing in Mobile Peer-to-Peer Networks (MP2PNs). To maximize cache sharing among clients, each client caches not only data objects but also parts of the index structure built on the spatial objects. Thus, we call the proposed method structure-embedded collaborative caching (SECC). By introducing a novel index structure...
Wiki is a collaborative writing tool. Applying Wiki to English writing can support peer revision effectively. Generally speaking, the Wiki-based platform of English writing set up on some official Wiki websites, which can't fulfill the needs of teaching, such as lacking adequate management support for the teaching of English writing. Our project designs and develops a Wiki-based Peer-revision Platform...
Vehicle trajectories are widely used in varies of applications. As to car navigation applications, typical usages of trajectories include correcting the digital maps, finding out the traffic jams, looking for the locations of cars. In this paper, it is assumed that trajectory data of expert drivers implies ldquobest practicerdquo routes, which will be helpful to naive drivers during driving. Therefore...
This paper focuses on the reputation of e-learning system services and the evaluation arithmetic. It gives out the content of reputation in e-learning services. In this paper, it adopts fuzzy hierarchy process quantitative analysis method to analyze the reputation service levels of the e-learning system evaluation, and gives the hierarchical structure and description of e-learning system's reputation...
