Support Mobile And Data Synchronous With Named Data Networking

The current internet architecture is increasingly challenged by the large-scale data distribution, the popularization of mobile devices, network data security and other fac-tors.Named Data Networking is the most influential instance of Information-Centric Networking, which may become a kind of future network architecture. Changing the existing communication model, such as using named data rather than the address in the hourglass, caching data in router, the consumer driving and ensuring data itself security with data signature technology, makes the NDN essentially support mobility, distribute the large-scale data and ensure data security.In this paper, the research content is the two aspects of mobile support and data syn-chronization application with Named Data Networking, and the following three issues are successfully solved:1) How to quickly and effectively forward the interest packet to the content source;2)How to successfully deploy mobility support scheme to a Seamless Mobile Visual Communication System project;3) How to design data synchronization application, which runs in the multi-user concurrency circumstance.The mobility support of Named Data Networking has been a hot research. How-ever, NDN can only support consumer mobility but not producer mobility. The vast majority of existing solutions support mobility by proxy server, which can bring the problem of flooding and network delay. Combined with the idea of hierarchical, mo-bility support scheme named MobiNDN with Named Data Networking is proposed, and we verify the correctness and performance of MobiNDN scheme with simulator experiments in ndnSIM.In order to verify the correctness of the MobiNDN and test its performance in real experimental platform, An experimental platform, which consists of ten network nodes, has been built on the campus network of University of Science and Technology of China. And On this platform, we successfully deploy an new project named Seam-less Mobile Visual Communication Using ICN Mechanism with routing management, mobility support, meeting management and privacy protection. In the end, MobiNDN scheme is proved that it is available and its performance is good by experiments.Data synchronization is a good research direction, which can play NDN’s advan-tages. ChronoSync, which can’t handle multi-user concurrency,is the first distributed synchronization application with distributed algorithm in NDN. In order to solve this issue, I propose a data set synchronization scheme named TreeSync based on time label, where the user can distribute in a tree topology in a time by the rule that high level users only can reply low level users. Using the new data structure to save data and record data state, TreeSync can complete group Internal data synchronization with the time label and three kinds of interest packets. In the end, our scheme is proved that it can not only deal with multi-user concurrency but also have robustness.
