Internet of Things

HTTP Commercial Process Module

The remote receives and sends commands to the internet of things access point via the HTTP

standard protocol. Hence, the ZigBee agent needs a web server. While there are many web servers,

for embedded systems, the GoAhead web server is a common choice. The web server is created

along with the device management framework which ensures that users do not have to work

with extra programs for application development supporting XML-RPC protocols and SOAP.

The primary goal of the web server is to oer support for JS (JavaScript) and ASP through

the use of the standard built-in CGI and the general CGI execution to run GoAhead, followed

by storing the files of the web pages on the file system or the ROM. Additionally, since this web

server is open-source in nature, therefore it can be used with a variety of platforms. Hence, it is

easy for the user to spread and edit the code easily.

Emergency Process Module

The ZigBee network’s switch from the power saving mode to the emergency mode is powered

by the Emergency Process Module. While remaining in the emergency mode, a short frame

is utilized by the ZigBee network which helps every device to report their observational data

with the coordinator.

Designing Smart Home

In order to oer control and access services to the remote users, a connection is established

between the IoT AP’s network layer and the ZigBee devices. Hence, a tablet or smartphone can

be used by the remote user for controlling those devices.

The following sections will describe the IoT access point development for a smart home

application. The paper defines two ZigBee devices with configurations; these are the on/o

power switch and the power meter. A simple home net business sells these devices while the

ZigBee alliance certifies them. First, we will discuss the ZigBee device configuration description

for the home automation system. Then we will present the wireless internet protocols and

lastly, we will discuss how the HTTP and UPnP are used for the verification of the ZigBee agent

operation.

ZigBee Home Automation Device Configuration

The paper mentions those ZigBee devices which the ZigBee Alliance certified to create the

ZigBee Home Automation Network. The internet of things access point establishes a connec-

tion with the on/o power switch, power meter, and the transceiver.

On/Off Power Switch

The use of this device is to maintain control of the power switch. There are two power switch

sets for the on/o power switch. Interface-wise, it comes with a wire which is tied to a nor-

mal home cable. The same wire can also establish a connection with the electronic device that

requires control. This switch boasts fixed power. Hence, the function is not too dissimilar to the

ZigBee networks’ power meter.

Power Meter

To determine the consumption of power and manoeuver the power switch, you can use the

power meter for the provision of power supplement with electronic devices, it comes with
