Introduction
Hoarders is a Perth based which requires to make his Perth office a smart office. The company
wants to install several smart devices in the main Perth office so that the operation of several
basic living is either controlled by a tablet or are fully automated. The company implemented the
IoT Smart Office for the client which provides a different level of experience and makes all the
work easy to implements. The company also wants to control the smart devices using the tablet
from its remote office which is in Kalgoorlie. Following are the list of smart devices that are to
be installed in the Perth office –
 1 x Ceiling Fan
 2 x Windows
 1 x Front Door
 1 x Carbon Dioxide Detector
 1 x Garage Door
 1 x Tablet Device
 1 x Wind Speed Detector
 1 x Lamp
All of these devices in Perth office needs to connect to a single Wireless router and the router
must be connected to a cable modem. The company will be using common ISP “Perth Pods” for
connecting Perth office and remote Kalgoorlie office. All the devices have a high-speed internet
connection so that they can communicate with each other and can carry the information related
to the detection by the sensors. The operation to be performed by the devices are basically
depend upon the program which is used when the sensors detect any object. The network
establishment will improve the connectivity between the nodes and provide optimized
connectivity.

Part 1
Designing the office of Perth according to the requirement of the company –
1. Adding the wireless router, tablet, cable modem, ISP cloud, and registration
server
Figure 1: Adding wireless router, tablet, cable modem and ISP cloud in Perth Office
In figure 1, we add a tablet to it connect through Wireless router in the Perth office which is
connected to the cables modem via Straight through cable. The cable modem is connected to the
ISP cloud using coaxial cable. The above image shows the infrastructure of the devices in the
office and how these devices are arranged so that the efficient network of IoT devices can be
developed.

Figure 2: Connecting Registration server to ISP
In figure 2, the registration server is connected to the ISP cloud using the straight-through cable.
The ISP provides the connection of the IoT devices to the internet and enables them to share the
information over the server.
Figure 3: Wireless Router Configuration
In figure 3, is the configuration of the wireless router in Perth Office. The configuration includes
setting up SSID to “OfficeNet”, authentication mode to WPA-PSK, passphrase to 11694267 and
6 | P a g e

encryption type to AES. The Encryption technique helps the system to securely transfer the
information from one node to another node. The process of transmission over the wireless
network increases the risk of attack on data or data loss, so the encryption technique is used. The
key is provided only to authorized users.
Figure 4: Setting up IoT service on the Registration server
In figure 4, is the setting up of IoT service over the Registration serve in which we have to just
switch on the service. The username and passwords are provided to the clients so that they can
access to the server. The IoT devices are set up on for the Registration server.

Figure 5: Setting up the service for DHCP on the Registration server
In figure 5, DHCP service is setup where DNS server is the IP address of the registration server
itself i.e., 111.10.20.30 and the pool IP address starts from 111.0.0.0 /16. The above image
shows the services setup for the DHCP which is responsible for the device or any user to get the
IP address so that it can connect to the internet and start the communicating.
Figure 6: Connecting tablet to the wireless router
In figure 6, we set SSID to “OfficeNet”, WPA-PSK passphrase to 11694267, and encryption
type to AES. The wireless network is established for the communication between the devices and
the system.

2. Connecting Smart devices and registering them to IoT server
Figure 7: Adding smart devices to the Perth office
In figure 7, we add all the smart devices that are required by the company like a door, fan,
windows, etc. The above image shows the setup for the smart office using IoT devices and
providing automation to the office. The smart office concept is implemented using IoT
technology.

Figure 8: Wireless Module to a smart device
In figure 8, the wireless module is added to the smart device. For this we have to select PT-IOT-
NM-1W module which is the wireless module and now the device can be connected using
wireless medium. This procedure is to be followed to all smart devices with respect to make
them wireless. The Wireless Network faces the issues related to the security so the main concern
while implementing the Wireless Network is on the security of the data.
Figure 9: Connecting smart devices to the wireless router
In figure 9, is the configuration that has to be followed for all the smart devices in order to
connect them to wireless router. For this set SSID to “OfficeNet”, WPA-PSK passphrase to
10 | P a g e

11694267, and encryption type to AES. AES is one the best algorithm of the encryption and
provided with the optimized methods.
Figure 10: Registering a user on IoT Registration Server
In figure 10, we register a user on the tablet via browser by accessing the web page on IP address
of Registration server i.e., 111.10.20.30. After opening this web page, we get an option to sign
up now. In that sign up now page we enter 11694267 as username and password and hit create.
