Design and Implementation of a Multiprotocol IoT Gateway

Jose Macias, Harold Pinilla, Wilder Castellanos, Jose Alvarado, Andres Sánchez

摘要:

在未来几年中,大量设备的互连预计将导致现实和虚拟世界之间的新形式的交互。在这个被称为物联网的前景广阔的场景中,预计不同的物体,如传感器,工业机器人,汽车,家用电器,将连接到互联网。物联网的主要挑战之一是高度异构设备的互操作性,主要是在所使用的通信能力和网络协议方面。因此,不同设备的互连模型涉及称为网关的中间设备。该网关是一个集中式元素,用于管理组成物联网应用程序的设备。此外,它对于将信息传输到互联网至关重要,特别是当许多物联网设备不是基于IP的时候。本文描述了物联网网关的实现,该网关允许通过不同的无线技术交换数据并将这些数据转发到互联网。所提出的网关具有重要的优势,如:支持多协议互连;远程配置无线节点的传感器和执行器管理;灵活的算法,将传感器获得的数据转换为统一的格式传输到云服务器;由于MQTT协议的高效数据传输,能耗低。为了证明所开发的网关的有用性,进行了概念验证测试。所实现的场景由2个无线节点组成,负责感测环境变量并通过不同的通信协议将数据传输到网关节点。所得到的结果表明,从远程无线节点到网关的同时数据传输的可行性。

英文摘要:

In the coming years, the interconnection of a large number of devices is expected, which will lead to a new form of interaction between the real and the virtual world. In this promising scenario, known as the Internet of Things, it is expected that different objects, such as sensors, industrial robots, cars, appliances, will be connected to the Internet. One of the main challenges of the Internet of Things is the interoperability of highly heterogeneous devices, mainly in terms of the communication capabilities and network protocols used. As consequence, the interconnection model of the different devices involves an intermediary device, known as gateway. This gateway is a centralized element for the management of the devices that make up an IoT application. In addition, it is essential for the transmission of information to the Internet, especially when many IoT devices are not IP-based. This paper describes the implementation of an IoT gateway that allows the exchange of data through different wireless technologies and forwarding of such data to the Internet. The proposed gateway has important advantages such as: supporting for multiprotocol interconnectivity; remote configuration of wireless nodes for sensor and actuators management; a flexible algorithm to translate the data obtained by sensors into a uniform format for transmission to a cloud server; low energy consumption due to efficient data transfer over the MQTT protocol. In order to demonstrate the usefulness of the developed gateway, a proof-of-concept test was implemented. The implemented scenario consists of 2 wireless nodes responsible for sensing environmental variables and transmitting data to the gateway node through different communication protocols. The obtained results show the feasibility for simultaneous data transmission from the remote wireless nodes to the gateway.
