The implementation of the smart home is done with the new version of packet tracer, precisely PacketTtracer 7.1.
The Table 3.1 below shows the lists of the different devices used for the simulation and their functions.

Methodology of the design:
Figure 3.3. Methodology of the Design
The network topology used for the implementation of the smart home is represented in the Figure 3.3 above. The implementation consist of four part: the smart home, internet cloud, Iot server and 3G network. [11]
In the first part, we have a home network with different internet of things devices connected to the home gateway (home Wi-Fi router in the topology).
The second part of the network is the internet cloud (WAN) which is connected to the home Wi-Fi router through a cable modem in order to provide internet connection to the internet of things devices.
The third part concern the IoT (internet of things) server that register all the devices connected to it to provide more internet of things functionalities.
Then comes the last part of the topology “3G network”, the smart phone is connected to the cell tower for internet connection in order to remotely access the devices
The Algorithm is explained as follows
Step 1: Start the project.
Step 2: Open the pkt file and save the file.
Step 3: Add the required components to the workspace
Step 4: Connect all devices in workspace using wireless connection. Step 5: Configure the devices and setup internet service provider router. Step 6: Add Home Gateway to the Network.
Step 7: Connect smart Devices to the Wireless Network. Step 8: Add End User Device to the Network
Step 9: Stop

Devices configuration
This Figure 3.5 below show the simulation of the smart home with cisco packet tracer using the Methodology described in the previous page.
Home gateway, cloud, ISP (internet service provider) router, central office server, IoT (internet of things) Server, cell tower, smart phone and the car play an important role in the simulation.
Figure 3.5. Smart home with Cisco Packet Tracer
-Home gateway = used for assigning IP address to the smart devices and for smart devices registration. The home gateway get the IP address from the ISP Router automatically after that the connection to the cloud WAN is established. Also all the smart object connected to
the home gateway get an IP address from ISP router automatically via the cloud (WAN). The cable modem is used to connect the home gateway to the cloud.
The home gateway provide different programing environment to the devices that are java script, python, and visual basic. [12, 14]
Figure 3.6. Home Gateway
In the Figure 3.6 above, we can see different smart objects connected to the home gateway using wireless or Ethernet cable connection.
There are four Ethernet ports in the home gateway plus a wireless access point with the SSID “home gateway”. We can configure WEP / WPA –PSK/ WPA2 protocols in the home gateway for the wireless connection authentication. [14]
In order to connect the devices to the home gateway, we must select wireless since the devices will be connected using wireless connection, then we specify the SSID of the home gateway in the devices.
This Figure 3.7 is the smart light configuration to the home gateway. The authentication is disabled to just to keep the configuration simple. So we repeated this configuration in all the devices.
Figure 3.7. Smart Light Connected to the Home Gateway
ISP Router (internet service provider) as shown in Figure 3.8 is used to connect all the network interfaces to each other, the DHCP server is configured on it in order to assign IP address to every connected devices dynamically, whether they are smart devices or not smart in order to simulate the internet connectivity.[11]
The ISP router configuration is done with the cisco packet tracer command line interface. The configuration consist of hostname assigning and IP address configuration
