【摘要】 总结了最新物联网发现服务,并结合半分布P2P技术提出了一种改进型EPC网络发现服务:根据物品流通特性对P2P网络进行分簇,并提出"互不干涉"策略来实现域内与域外不同的信息传递方式。本服务可以及时处理冗余信息及垃圾信息,使网络通信更加快捷畅通。改进后的系统在提高查询效率,减轻超级节点的负担、减少对超级节点的依赖,提高信息安全等方面有很大进步。更多还原

【Abstract】 The latest discovery service methods are summarized.And a new EPC network discovery sevice based on the hybrid P2P structure is put forward.According to the caracters of goods,the P2P network is clustered.And put forward "non-interference"strategy to realize the different information transfer between the intra-domain and extra-domain.Redundant information and rubbish on the network can be cleaned out soon.After amelioration,the system is greatly improved increasing searching efficiency,alleviating supper-point’s burden and so on.更多还原
