Wireless Network And Network Setup - Engineering Assignment Help

Assignment Task

OBJECTIVES: 

Upon completion of this lab, the student will be able: 

• To learn about the wireless network architecture. 

• To investigate different architectures of wireless networks. 

• To analyze the performance of wireless network under different design parameters.

NETWORK SETUP: 

In this example we will build a simple wireless network scenario. In this scenario, a network is consists of  five (5) wireless hosts placed randomly in 200 x 200 m2 area. The goal of this example is to investigate the  effect of CSMA/CA back-off time on the average delay. 

Create a new network descriptions file (.ned) file, with a network (WLAN). 

Place a Host module, channelmanage, and nlist module in the network space as in Figure 3.  

In this laboratory exercise we are going to create a module that works as a hub. Firstly we need to create a source file, where we describe the functionality of the model in terms of initialize stage  and through receiving message (handlemessage) stage.

In the source of the .ned file create a variable for number of hosts. 

And modify the Host module to an array of number of hosts. 

Create a new .ini file for the simulation run. 

In the .ini file, assign IP addresses for all hosts. 

Specify the background size (200 x 200), and number of hosts to be 5.
