Today's age of information and communications technologies (ICTs) in urban areas revolves around the application of the Internet of Things (IoT) and application of IoT in smart city constructs. IoT has enabled cheap but reliable ubiquitous computing for modern day ICT needs. As a result, the military community is actively looking into application of IoT for its operational needs. Federation and interoperability become complex for IoT implementation in the huge jungle of protocols and technologies available for IoT. This problem becomes critical in humanitarian assistance and disaster recovery operations where multiple agencies need to collaborate to bring quick and effective relief to disaster struck areas. Message Query Telemetry Transport (MQTT) is such an IoT-based protocol that is widely adopted in the industry for lightweight but reliable messaging. This article tries to provide insight into federation based on MQTT with a prototype implementation between military and civilian ICT systems. This federation concept would enable lightweight, vendor-agnostic, and interoperable message exchange while using existing information sources and preventing stove-piped systems.

基于MQTT的联邦用于城市人道主义援助和灾难恢复行动

当今城市地区的信息和通信技术（ICT）时代围绕着物联网（IoT）的应用以及物联网在智慧城市建设中的应用。物联网使廉价，可靠的普适计算能够满足现代ICT的需求。因此，军事界正在积极地研究物联网的应用以满足其运营需求。在物联网可用的协议和技术的巨大丛林中，联合和互操作性对于物联网实施变得复杂。这个问题在人道主义援助和灾难恢复行动中变得至关重要，在人道主义援助和灾难恢复行动中，多个机构需要合作，以便为受灾地区提供快速有效的救济。消息查询遥测传输（MQTT）是一种基于IoT的协议，已在业界广泛用于轻量级但可靠的消息传递。本文试图通过军事和民用ICT系统之间的原型实现来提供对基于MQTT的联合的见解。这种联盟概念将在使用现有信息源并避免使用炉灶式管道系统的同时，实现轻量级，与供应商无关且可互操作的消息交换。
