摘　　要：依据RFID网络特征和行为的形式化描述,基于发布/订阅系统构建了RFID网络模型。RFID网络是构建在IP网络层之上的重叠网,借助代理(broker)的消息存储转发、匹配和路由机制,实现阅读事件的多对多异步通信,阅读事件与应用之间无须预先确定相关关系。实验验证了这种网络模型的有效性,可以满足将来大规模泛在RFID应用的需求。According to the formal description of the properties and behaviors of RFID （radio frequency identification） network, RFID network model based on publish/subscribe system was established. RFID network belonged to a kind of overlay network built on IP networks, where many-to-many communication was set up for reading events asynchronously with aid of brokers which store and forward, match and route messages by the designed mechanisms, and relations between RFID readings and their applications didn＇ t need prearranged. Experiments show good effects of such a new model, which can be used for meetingwith the demands of large scale ubiquitous RFID applications in the future.
