Token transmit in ring-link P2P network in the form of message, and node information could record in token in order to keep the structure of network for other nodes. P2P network use control speed parameter to reduce the number of tokens. Simulation shows that control speed parameter could effectively reduce the number of token in P2P network; with the increasing scale of the network, the average maintenance costs of node remain unchanged.","PeriodicalId":221663,"journal":{"name":"International Conference on Electronic and Mechanical Engineering and Information Technology","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115209655","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
