Abstract

This paper proposes a novel design methodology of Constrained Application Protocol (CoAP) protocol for an IoT-enabled mobile robot system to operate remotely and access wirelessly. These devices can be used in different applications such as monitoring, inspection, robotics, healthcare, etc. For communicating with such devices, the different frameworks of IoT can be deployed to attain secured transmission using different protocols such as HTTP, MQTT, CoAP, etc. In this paper, the novel IoT-enabled communication using the CoAP protocol in mobile robotic systems is attempted. A mathematical analysis of the CoAP model is carried out where this protocol provides a faster response within less time and less power consumption as compared to other protocols. The main advantage of the CoAP protocol is to facilitate Machine-to-Machine (M2M) communication which contains features like small packet overhead and less power consumption. An experimental prototype has been developed and several trials have been conducted to evaluate the CoAP protocol's performance for rapid communication within the mobile robotic system. Signal strength analysis is also carried out. This reveals that the reliability of sending signals is up to 99%. Thus, the application of the CoAP protocol shows enough potential to develop IoT-enabled mobile robotic systems and allied applications.

摘要

本文提出了一种新颖的受限应用协议（CoAP）设计方法，用于支持物联网的移动机器人系统进行远程操作和无线访问。这些设备可用于不同的应用，如监测、检查、机器人技术、医疗保健等。为了与这些设备进行通信，可以部署不同的物联网框架，以使用HTTP、MQTT、CoAP等不同协议实现安全传输。本文尝试在移动机器人系统中使用CoAP协议进行新颖的物联网通信。对CoAP模型进行了数学分析，与其他协议相比，该协议在更短的时间内提供更快的响应，且功耗更低。CoAP协议的主要优点是便于机器对机器（M2M）通信，其特点包括小数据包开销和低功耗。已经开发了一个实验原型，并进行了多次试验，以评估CoAP协议在移动机器人系统内进行快速通信的性能。还进行了信号强度分析。结果表明，信号发送的可靠性高达99%。因此，CoAP协议的应用显示出开发支持物联网的移动机器人系统及相关应用的巨大潜力。
