Introduction
The client wants the office must be designed smartly. The Office must support all the services
based on IoT devices where these devices are connected with each other through wireless sensor
networks. The IoT devices provided with the support of the server so that they can transfer the
information from one node to another. The company Gold Grabbers provide Computer services
and networking support so the designing of the IoT Smart Office task is assigned to the Network
Engineer (Cicirelli, et al., 2018).
The Office will be provided with the smart devices which include smart fans, smart door,
detector of CO2, Table Devices, Wind Speed Detector, Smart Lamp, etc. These devices will help
the employees to live smart life and the work become easy. The Office needs to be designed in
such a way that most of the work is performed in automatic way. The devices must be connected
with the wireless network and connected to the internet via ISP. There are several tasks to be
done for implementing the Smart Office design which includes adding different smart devices
and establishing a wireless network for connection. The proposes report include the steps and
other design for implementing the infrastructure based on smart devices.

Smart Office Design
1. Configuration of the Server
Figure 1: Main office
All devices connected as a requirement used devices in main office:
Windows (2) – The windows are designed in such a way that it can automatically close and open
according to the requirements.
Front Door – The Front door is opened and closes most of the time. The door gets open when
detecting the person coming near and get closed when the person goes out of reach.
Garage Door – The Automation is provided to the Garage Door also.
Lamp – The lamps are designed smartly that they start up when the room becomes dark there is
less light.
Wind Speed Detector – The Detector is placed for detecting the speed of the winds. The
warning is given if the speed goes high.
Ceiling Fan – The Ceiling fans are designed smartly which have the automation in the work and
work according to the detection. If the fan detects human then it will start working.
Carbon Dioxide Detector – The detectors are placed which detects the level of CO2 in a room.
Tablet Device – The tablet devices are used to control the function of the Smart Office.

We have a registration server in the ISP network:
Figure 2: ISP network
The IPS provide connection of these devices with the internet so that they can transfer the
information from one node to another. The devices are connected with the IPS using router.
There is a switch between the registration server and ISP cloud acting as a layer2 switch, not
more.
Figure 3: Registration server enabled
In the picture above, we can see the server is enabled but there is not any username and password
yet. Next step creating username and password.
Figure 4: User registration
To create username and password firstly need to access the registration server over tablet in main
office we can use server IP address to access in picture used domain. Username and password
are 11694652.

Figure 5: Check is it created or not
After registration, we can check it on IoT tab in the registration server. IoT devices are connected
with each other using the internet and transfer the information using the internet. The node to
node data is transferred.
Figure 6: DHCP settings on the server
DHCP is configured on server and subnet mask is 255.255.255.128, all clients will get IP starting
from 89.42.125.11. Dynamic Host Configuration Protocol (DHCP) performs the dynamic
assigning of the IP address.
Figure 7: DNS settings
DNS service also enabled on the server and added one A record. After that clients can access to
server from tablet or workstation with this domain. The clients are provided with the Tablet
which controls all the functions in the smart office by the smart devices. These Smart Devices
are provided with the internet connection which helps these devices to work according to the
command received by the tablet.

Figure 8: IP address configuration
The IP address of server is 89.42.125.10 and it is configured statically. Previously DHCP starting
IP address configured to 89.42.125.11 with that prevented IP conflict. The IP conflict is the
situation where the two devices got the same IP address and these devices are considered as End
Points. This will cause anyone forms these endpoints to be unable to use the Network (Cianfrani,
Listanti & Polverini, 2017).

2. Configuration of the wireless devices
Figure 9: Wireless Configuration on main office wireless router
SSID of is wireless network is OfficeNet. The authentication method is WPA-PSK and PSK pass
phrase is 11694652. Encryption is AES. As the security is required for the proposed design so
the designing of the server using the AES algorithm will enable the user to protect the network
from unauthorized access and the organizational data is also protected for fraud.
Figure 10: LAN network configuration
LAN network of the main office;
IP address 172.16.10.1
Subnet 255.255.255.0.
All IoT devices in the main office getting IP from router in these ranges. The range is also
important to consider ass the data transmission need continues connection so the range of LAN
network must be high and continues (Liang, Yu & Zhang, 2015).
Figure 11: WAN interface settings
WAN interface of WIFI router is getting IP from the server DHCP pool. DHCP pool provides
the IP for the clients on the server so that they can use the IP address for accessing the internet.
The operation can be performed by the device on the Network.

3. Setting up of the Smart Devices in Office
Configure the Smart Devices to register with Registration Server first need to connect office
wireless router all devices for that need to enable wifi adapter. This will help to connect all the
devices with the server or network.
Click the Device icon in the workspace to open the device configuration window, and push the
"Advanced" button near the bottom right of the window
Click the I/O Config tab -> Network Adapter -> choose PT-IOT-NM-1W (this is a wireless
network adapter)
Figure 12: Wireless adapter configuration
Figure 13: Wireless configuration
Next Config tab
Selected Wireless0 tab from left. Entered OfficeNet for the SSID.
Then selected WPA-PSK and entered PSK Pass Phrase 11694652.
AES is automatically chosen for Encryption.
Figure 14: Registration to server

Selected left Settings tab in the Config tab. Display Name as Smart Device.
Gateway/DNS IPV4 to DHCP.
Changed the IoT Server type from Home Gateway to Remote Server. Entered the IP address of
the server 89.42.125.10 and the IoT account User Name 11694652 and Password 11694652
created earlier.
Clicked the Connect button. Once connected the Connect button change to Refresh
Figure 15: Login to the server from tablet
Sign in to the server with domain www.mukheshreddy.com. Username is 11694652 and
password is 11694652.
Figure 16: Devices connected to the server
After signing in we see all connected devices to the registration server. Now we can control all
devices from here. All the devices are provided with the one point controlling and can be
accessed from this point. The tablets are used for controlling all the functions in the Smart
offices.

4. Protocols setup for transmission
Figure 17: Devices connected to the server
Devices communicating with the server over TCP protocol and used port 31000. The
communications between the devices are important to consider as the communication is only the
reason for establishing the network. The above image shows hows the devices are connected
with each other in the server.

5. Remote Branching
Figure 18: Remote branch
The remote branch connected directly to ISP cloud network. The cloud network is provided with
the cloud where all the data and related information are stored. The proposed system contains the
cloud where all the data related to the smart system are stored and necessary tasks are performed
using these data. The Remote branch work on the basis of these cloud network which also
provided with the cloud services.
Figure 19: Branch office inside the network
Figure 20: WAN interface of the wireless router
WAN interface is configured DHCP and router getting IP from the server. The above image
shows the WAN interface using wireless router. This shows how the network can be considered
in terms of routing.
