Task

This Assignment assesses the following module Learning Outcomes (from Definitive Module Document):

Successful students will typically:
LO1: have a knowledge and understanding of the complex problems and issues arising when mobility occurs in networks.
LO2: have a knowledge and deep understanding of the complex problems and issues arising when network applications have different quality of service requirements.
LO3: be able to discuss and critically evaluate protocols intended to solve problems or address new applications that arise in mobile networking.
LO4: be able to articulate and critically evaluate protocols intended to solve complex problems or address new applications that arise in multimedia networking.
 
Task 1
Write a python script to emulate the following environment. Completion of this task will require the knowledge and understanding of the lab material and will require extra knowledge that can be obtained through self-study and research. The topology should be as the following illustration.
 
The illustrated topology in Figure 1 consists of 6 access points and 4 stations. The stations can represent a smart hand-held device which can vary from to a laptop, UE or to any WiFi compatible device. The topology above should be pushed towards the Mininet API using a python script with the following information and criteria. Please adhere to the mentioned settings and configurations and deviating from the given settings may reduce the full marks given.
