物联网（IoT）出现的时间并不长。这是一个不断发展的新概念。无处不在的计算、无线技术、传感技术、互联网协议（IP）和设备混合在一起，以便设计一个系统，在该系统中，虚拟或抽象世界与真实的世界相遇，并且它们彼此持续地交互。无线传感器网络与物联网集成可以创造奇迹。在传感器领域部署了许多传感器，所有这些传感器都通过物联网网关将其生成的信息发送到云中的应用程序，这有助于将传感器的内部网络与万维网连接起来。不同类型的传感器向网关转发不同类型的信息。例如，存在发送关于温度的信息的温度传感器、将关于患者的心跳的信息发送给医生的传感器等等。本文的目的是优先级的流量/数据由不同的传感器产生的消息队列遥测传输传感器网络（MQTT-SN）网关，以减轻延迟的数据包，这是必要的时间关键型应用程序。
It has not been much time since the Internet of Things (IoT) came into existence. It is a fresh concept that is always evolving. Ubiquitous computing, wireless technologies, sensing technologies, Internet Protocol (IP) and devices are mingled together in order to devise a system where the virtual or abstract world meets the real world meet and they interact continuously with each other. Wireless Sensor Networks on being integrated with IoT can work wonders. There are numerous sensors deployed in the sensor fields, all of them sending information generated by them towards an application in the cloud through an IoT gateway which helps to bridge the internal network of sensors with the World Wide Web. Different kinds of sensors forward different types of information towards the gateway. For instance there are temperature sensors that send information regarding temperature, sensors that send information about a patient’s heart beat to the doctor and so forth. The objective of this paper is to prioritize the traffic/data generated by different sensors in a Message Queue Telemetry Transport for Sensor Networks (MQTT-SN) Gateway in order to mitigate the delay of data packets which is necessary for time critical applications.
