论文摘要
将常规的事物/对象连接到Internet可以从任何地方监视和控制此类事物，通常称为物联网（IoT）。事物之间或与其他实体（例如服务器）之间进行交流，以便可以从事物中收集信息，同时可以采取适当的措施。许多物联网应用程序采用的突出的通信方法与出版/订阅（P/S）范式有关。任何愿意提供一些数据的通信实体都会向服务器（代理）宣布其意图，并将自己确立为此类数据/主题的发布者。愿意接收任何已发布数据的实体，将自己注册为经纪人作为订户。只使用一个经纪人可能会导致瓶颈和单点失败，而当拥有多个经纪人时，一个人最终可能会遇到困难。这项工作为独立经纪人联合会提供了可扩展，有效的提案，无论经纪人出版商和订阅者与哪种经纪人相关联，订阅者都可以获取所有出版物。
Connecting usual things/objects to the Internet allows the monitoring and control of such things from anywhere, which is usually referred to as the Internet of Things (IoT). Things communicate among themselves or with other entities (e.g., a server) so that information can be gathered from things whilst proper actions can be taken upon them. A prominent communication approach adopted by many IoT applications is related to the Publish/Subscribe (P/S) paradigm. Any communication entity willing to provide some data announces its intention to a server (broker), establishing itself as a publisher for such data/topic. Entities that are willing to receive any published data, register themselves to the broker as subscribers. While employing just one broker might lead to a bottleneck and a single point of failure, when having multiple brokers one could end up having difficulties with their management. This work presents a scalable and efficient proposal for the federation of independent brokers, by allowing subscribers to get all their publications no matter to which broker publishers and subscribers are associated with.
