Introduction

You are given a scenario based on Wireless Sensor Network to simulate using Network Simulator 3 (NS-3) OR Matlab environment. You need to set up the network using appropriate topology, and select appropriate protocol layers for the application given, and generate data points for variables as per the instructions below. Each data point must be an average of five simulations.

Coursework specifications: You can choose option I or II

Option I

  1. Create a 500x500 grid of sensor nodes
  2. Select an appropriate application for the above WSN grid
  3. Incorporate appropriate values for initial energy level at the nodes; appropriate combination of static and mobile nodes
  4. Choose appropriate topology, and run the simulation for ANY TWO of the protocols: Flooding, AODV, DSDV, DSR and LEACH; Use the simulation run time of 20.
    1. Evaluate and compare the performance of the routing protocols by measuring ONE OF THE COMBINATIONS given below of the following network parameters over a period of time.
      1. Throughput
      2. PDF
      3. End-to-end delay
      4. Energy consumption at node/network level
      5. Remaining energy of the sink
      6. Evaluate the performance of WSN in terms of the parameters given in section E against the variable ‘network size’ (ranging from 10, 50, 100 etc. nodes or similar ratio) of which 10% of the nodes are mobile (choose your own mobility patterns).

COMBINATIONS: (i and iii), (i and iv), (i and v), (ii and iii), (ii and iv), (ii and v), and (iv and v)

Option II

  1. Create a grid of sensor nodes; Use 100 nodes to start with.
  2. Incorporate appropriate values for initial energy level at the nodes; appropriate combination of static and mobile nodes
  3. Choose appropriate topology, and run the simulation for LEACH protocol; Use the number of rounds as 100 to start with.
  4. Evaluate and compare the performance of the routing protocol by measuring the following network parameters over a range of ‘number of rounds’.
    1. Throughput (Number of packets received by the BS)
    2. Number of dead nodes
    3. Energy consumption at node/network level
    4. Evaluate the performance of WSN in terms of the parameters given in section D against the variable ‘network size’ (100, 200, 300, 400 and 500 nodes) of which 10% of the nodes are mobile (choose your own mobility patterns).
    5. Evaluate each of the network size for a range of ‘number of rounds’ (100, 300, 500, 800 and 1000). You will need to discuss the network behaviour and the rational in detail in your report.

Assessment and Feedback

Assessment of the CW is via submission of a written report by 9th May 2021. A written feedback will be provided by 4th June 2021. This is an individual assessment.

Marking Scheme: The marking scheme for the CW is given in the following table

Marking scheme for the assignment

Component

Marks

The sensor network is setup correctly in terms of topology and protocol layers. The simulation generates data points without error.

30

A

The report explains the simulation setup, process, and the results well. The simulation results are presented clearly using a range of format including tables, graphs etc.

25

B

The report includes a detailed original discussion around the performance evaluation of the network based on the results obtained.

20

C

The report follows appropriate structure prescribed for a standard technical report and includes a range of sections (for example, but not restricted to introduction, literature review, simulation and analysis, conclusion and suggestions for future work, references) to the benefit of the report.

15

D

The report includes appropriate literature review and referencing system

10

E


Recommended reading:
Class notes and supplementary information from Canvas, and literature search using appropriate search tools.

Problems completing your assessment – what to do if you are unable to complete an assessment

If something serious happens that means that you will not be able to complete your assignment by the deadline, you need to contact the module leader as soon as possible. There are a number of things that can be done to help, such as extensions, and alternative assessments, but we can only arrange this if you tell us. To ensure that the system is not abused, you will need to provide some evidence of the problem. More guidance is available at                      https://www.ljmu.ac.uk/academic-registry/student/registry-services/assessment- coursework-and-examination/problems-completing-your-assessment.

NOTE: Any coursework submitted late without the prior agreement of the module leader will receive 0 (zero) marks.

Academic Misconduct

The University defines Academic Misconduct as ‘any case of deliberate, premeditated cheating, collusion, plagiarism or falsification of information, in an attempt to deceive and gain an unfair advantage in assessment’. The School takes Academic Misconduct very seriously and any suspected cases will be investigated through the University’s standard policy (Academic Misconduct Policy). If you are found guilty, you may be expelled from the University with no award.

It is your responsibility to ensure that you understand what constitutes Academic Misconduct and to avoid it – your programme guide contains further information.
