Practical 4
Aim:
To create and simulate a simple Ad hoc network.
Devices / Tools Used:
Computer System, Wireless Routers:-2, PCs:-5, Cisco Packet Tracer.
Practical 5
Aim:
To understand, read and analyze the routing table of a network.
Devices / Tools Used:
Computer System, Router PT:-3 , SwitchPT:-3 , PCs:-3 , per pair Cisco Packet Tracer.
Step 1:Open the Cisco Packet Tracer software.
Step 2:After successfully starting, go to Routers and select Wireless Router (Router-PT).
Step 3:Go to Switches and select PT-Switch.
Step 4:After that, go to End Devices and select PCs.
Step 5:Then go to Connections and select the first wire (copper straight-through) to connect all the devices.
Step 6
Write the IP addresses that you have to assign to each device.
Step 7:Assign the IP address to all devices.
Step 8:Hover on the router wire and see the router cable name.
Step 9:Then go to Config → Ethernet type and assign the IP address to the router by clicking on that particular router.
Step 10
Now it is time to connect the routers. Hover on the wire between routers and complete the connection.
Step 11: Then give IP to routers. If your wire symbols turn green, it means your connection is correct.
Step 12: That’s it. If all red symbols turn green, then all your connections are correctly connected.
Step 13: Now it’s time to set all IPs in RIP on all routers. For this, go to router settings, then Config, and select RIP.
Step 14: Now it’s time to check whether our message is transmitted to all devices or not. Sometimes it may show failed because it needs to wait 30–40 seconds to connect, so retry the transmission.
Step 15: If the message is sent or received properly, then you have successfully completed this practical.
Practical 6
Aim:
To implement a Wireless Sensor Network simulation.
Step 1
Open the Cisco Packet Tracer simulator on your computer.
Step 2
After the software starts, go to Network Devices and select AccessPoint-PT.
Step 3
Go to End Devices and add the following devices to the workspace:
PC
Laptop
Tablet
Smartphone
Step 4
Connect the PC and Laptop to the wireless network:
Click on PC
Go to Physical tab
Turn the device Off
Remove the existing port/module
Add the wireless module linksyswmp300N
Turn the device On
Step 5
Repeat the same wireless module installation process for the Laptop.
Step 6
For security, configure the SSID on the Access Point:
Click Access Point
Go to Config → Port
Enter SSID
Enter WEP Key
After this configuration, the connections will appear disconnected.
Step 7
Connect the PC to the Access Point using the SSID:
Click PC
Go to Desktop
Open PC Wireless
Click Connect tab
Select the Wireless Network Name (SSID)
Enter the WEP Key
Step 8
Repeat Step 7 for the Laptop.
Step 9
Connect the Tablet and Smartphone:
Click the device
Go to Config
Select Wireless0
Enter the SSID and WEP Key
Now all the devices should be connected to the wireless network.
Step 10
Test the connection:
Send a message (or ping) from PC to Laptop.
✅ Result: The Wireless Sensor Network simulation is successfully completed.
Practical 7
Aim:
To create MAC protocol simulation implementation for wireless sensor network.
Devices / Tools Used:
Computer System, Wireless Router, PC, Laptop, PC, Smartphone , leptop , pc Cisco Packet Tracer.
Practical 8
Aim:
To simulate Mobile Ad hoc Network using directional antenna.
Devices / Tools Used:
Computer System, Home Gateway, Smartphone, IoT Devices (Fan, Light, Window, Motion Sensor), Cisco Packet Tracer.
Practical 9
Aim:
To create a mobile network using cell tower, central office server and web server and simulate the connection between them.
Devices / Tools Used:
Computer System, Wireless Router, Cell Tower, Central Office Server, Web Server, Smartphone, Router, Hub, Cisco Packet Tracer.
Step 1
Open the Cisco Packet Tracer software or simulator.
Step 2
After successfully starting the software, go to Network Devices → Wireless Devices and select:
WRT300N
Cell Tower
CO-Server (Central Office Server)
Step 3
Then go to End Devices and select:
Smartphone
Server-PT
Step 4
Go to Network Devices → Hub, select Hub-PT and then go to Router and select 1841 Router.
Step 5
Make the connection with the appropriate wire and devices.
Use Copper Straight-Through wire for the following connections:
WRT300N ↔ Hub-PT
Hub-PT ↔ 1841 Router
Hub-PT ↔ Central-Office-Server
Use Copper Cross-Over wire for the following connection:
1841 Router ↔ Server-PT
Use Coaxial wire for the following connection:
Central-Office Server ↔ Cell Tower
Step 6
Set the IP Address so that packets can be transferred from one device to another.
WRT300N
Config → Internet → Static
STATIC IP Address: 20.0.0.2
Gateway: 20.0.0.1
1841 Router
FastEthernet0/0 → 20.0.0.1 → Click ON
FastEthernet0/1 → 21.0.0.1 → Click ON
Server-PT
Gateway: 21.0.0.1
FastEthernet0/0: 21.0.0.2 → Click ON
Now all red symbols will turn green.
Step 7
Send a packet from Smartphone to Server-PT.
(It may take a few seconds to connect, so initially it may show Failed.)
If the connection status is Successful, then the practical has been successfully performed.
