Analyzing the network coding and its application in mobile P2P network, a novel network coding dynamic node selection method in mobile Peer-to-Peer (P2P) network is proposed, which the hierarchical network structure divides the nodes into super node (SN) and ordinary node (ON). Considering the heterogeneous and dynamic characteristics, Part coding node (CN) selection program is adopted, which overcomes the defects of the current popular overall coding selection method. Comparing the centralized structure and overall distributed one, semi-distributed topology is used to balance the network load and maintain the unified management, which SN and ON is collaborated to manage network. Except that, the CN number evaluation mechanism based on feedback reflects the network environment changes, and can adjust the system parameter adaptively, which makes the whole system is fit for the real mobile P2P network. The simulations made by NS-2 verify the better performance of network coding than the traditional storeand-forward mechanism.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
