Abstract

Network communication and micro-electro-mechanical embedded technologies have attracted much attention in recent years. Through these technologies, the capabilities of sensing, identification, and communication can be embedded in various smart devices. These smart devices can automatically connect to the Internet and form an intelligent network called Internet of Things (IoT). However, these devices are embedded with different wireless communication interfaces such as Wi-Fi and ZigBee. This paper presents the design and implementation of an IoT access point that supports functionalities of coordination of various wireless transmission protocols. Based on the existing Wi-Fi access point, we have embedded a ZigBee module and implemented ZigBee and UPnP protocols into the designed IoT access point, which supports ZigBee communication capabilities over the Internet.

Summary

Introduction

The Internet of Things (IoT) has attracted much attention because of the provided functionalities that can advance humanity in terms of intelligence, automation, convenience, etc. The smart power meter sends information wirelessly to the access point and the information is further forwarded to user devices through the Internet. Numerous wireless technologies had been integrated and designed for various purposes, most applications of smart home neglect a well-designed wireless technology—ZigBee. ZigBee is an efficient short-range wireless technology in terms of power consumption and deployment scalability [21]. ZigBee is an efficient short-range wireless technology in terms of power consumption and deployment scalability [21] It is a low-power wireless transmission protocol, providing a suitable data rate for control and monitoring purposes. After designing the working system in an access point, we implement the IoT AP that is suitable for convenient deployment in a smart home and covers both the gateway and AP.
