Assignment: Wireless Networks and Security
Purpose
The purpose of the assignment is to compare the wireless communication technologies and evaluate their performance. Students will be able to complete the following ULOs:
a. Compare standards-based technologies used in various networks;
b. Test and evaluate various wireless networks performance;
Length: 1500 - 2000 words.
Description
Wireless networks performance varies from wired networks, the latter uses a guided medium and wireless networks use unguided medium for transmission. To design and simulate wireless networks the network simulator - 2 (NS - 2), an open source discreet event simulator could be used. The NS-2 simulator is a widely used simulation tool, which could generate trace files for analysis and comes with a network animator to visualize the network performance.
This assessment requires students to compare and evaluate the performance of wireless routing protocols using the NS-2. The assessment requires students to design a wireless network topology in NS-2 and evaluate the generated trace files for two different wireless routing protocols. The students are required to carry out a critical analysis of the results of the two routing protocols, by plotting graphs and discussing the outcomes.
This things have to be done.
1. Design a wireless network consisting of 20 nodes; the dimensions for the given topology are 400x300. The agent type should be UDP and the traffic CBR. The simulation should run for 300 seconds. Uniform deployment of nodes is required and the nodes are required to transmit packets over the network. The wireless node configuration should include the NS-2 energy model.
2. Run the simulation on two different routing protocols such as DSDV, AODV, DSR, and TORA. Critically analyse the trace files in terms of packets sent, received, dropped and energy consumed. These parameters should be plotted on graphs and discussed in detail
3. Include screenshots of the NAM displaying the nodes uniformly deployed during the simulation and add at least 3 screen shots of the simulation.
4. Appendix I should include the tcl script used in each simulation.
Format your assignment according to the following formatting requirements:
1. The answer should be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides.
2. The response also includes a cover page containing the title of the assignment, the student's name, the course title, and the date. The cover page is not included in the required page length.
3. Also include a reference page. The Citations and references should follow APA format. The reference page is not included in the required page length.
