assignment in wireless network sensor and IOT ..

• This assignment gives a large room for the student to be innovative and to propose their own ideas
• Marks will be awarded as follows (details is in the rubric on Canvas) o Depth of literature review
  • Figures, plots and illustrations (drawn by the student) o Clarity of writing and equations o Novelty and innovation o Sound assumptions and parameters o Simulation code o Proper references
• The assignment should be written in LaTeX format using IEEE Conference Template. It is suggested to use the online Overleaf editor on: https://www.overleaf.com/project. Feel free to use any other LaTeX editor (online or offline).
• Use IEEE citation style
• It is expected to have a document of 4-6 pages long – double column format (3000-4500 words) – excluding the code which should be submitted separately
• The student is expected to develop a code to simulate/analyze the selected concept, the code needs to be neatly written with clear annotation (comments). Also, it needs to be consistent with the assignment text and well explained.
  • The code needs to be (written in ASCII format) with sufficient annotation to allow the examiner to understand the code. o Coding/scripting language needs to be either in Matlab (or Simulink), Python, or

C/C++

• It is indeed allowed to use libraries and functions (both built-in and external), however it should be clearly identified in the code which part was developed by the student and which part was taken from other sources.
• The code contribution of the student should be significant and not just adjusting available online codes

• State your assumptions inside the assignment document! Marks are awarded to sound assumptions
• Important note about plagiarism:
  • You should write the assignment yourself. Under no circumstances any part of this assignment can be written by anyone else (unless otherwise

some quoted text is clearly stated and referenced)

• Plagiarism will not be tolerated and heavy loss of marks (or zero mark) will be incurred with possible wider academic penalties.
• The rules apply similarly to the developed codes

Topics

Below are the topics that will be allocated to students,

Topic 1 Radio coverage designs for LPWAN access network (undergraduates)

The objective is to design radio coverage (downlink) for a NB-IoT access network to cover Melbourne metropolitan area. The project will use existing cellular tower locations as provided on Canvas (“TowersLocations.csv”, assume the tower height as 30 m). The main outcomes of the project are:

• The project will provide literature review for (but not limited to):
  • Brief overview of NB-IoT standard o NB-IoT coverage and performance o NB-IoT limitations
  • State-of-the-art coverage design approaches for NB-IoT (or in Cellular coverage in general)
• Map(s) showing the locations of the import sites locations
• Graph(s) for the Block error rate (BLER) vs. SNR (for two repetition rates 1 and 32)
• Graph (s) for the radio coverage of NB-IoT (in terms of the received signal strength – dBm)
• Graph (s) for the radio coverage of NB-IoT (in terms of the signal to noise ratio)
• Two plots for coverage contour for two different repetition rates 1 and 32. Take 5% BLER as the threshold
• Additional figures and results as needed

Hints: 

• You could make use of Matlab NB-IoT package to extract the block error rate (BLER) vs. SNR and utilize this for mapping the SNR into coverage. See this tutorial.
• You could make use of Matlab “RF Propagation” toolbox. See this example.
• You could make use of geoplot function in Matlab to show the location of the towers
• See 3GPP recommendations for NB-IoT design parameters (noise floor
• Use transmit power of 40 watts with 3 directional antennas at each site (each having gain of 12 dBi)
• Use frequency 900 MHz for the simulation
• Use Longley-Rice model as your radio    propagation

model

If something is not stated in the question       use       your    own assumptions       and      explain             the reason for such selection.

Topic 2 IoT (LPWAN) access network over UAVs (Post-graduates)

This project is similar to “Topic 1” where the objective is to simulate the downlink radio coverage for an NB-IoT eNB (base station) fitted onboard of a flying UAV. The location of the UAV is over Melbourne CBD, hovering above the intersection of Bourke Street and Elizabeth Street. The project will make use of the open street map file on canvas “melbourne.osm” that includes the buildings’ height as shown in the figure below. The main outcomes of the project:

• The project will provide literature review for (but not limited to):
  • Brief overview of NB-IoT standard o NB-IoT coverage and performance o Using UAV for providing cellular coverage (what are the pros / cons of UAVs) o State-of-the-art coverage design approaches for NB-IoT (or in Cellular coverage in general)
• Map(s) showing the buildings and the UAV (as points at different heights 30 m , 90 m, 120 m, 150 m, 250m)
• Graph(s) for the Block error rate (BLER) vs. SNR (for two repetition rates 1 and 32)
• Graph(s) for the radio coverage of NB-IoT (in terms of the received signal strength – dBm) for heights 30 m , 90 m, 120 m, 150 m, 250 m.
• Graph(s) for the radio coverage of NB-IoT (in terms of the signal to noise ratio) for the specified heights
• Four plots for coverage contour for two different repetition rates 1 and 32. Take 5% BLER as the threshold
• Additional figures and results as needed

Hints: 

• You could make use of Matlab NB-IoT package to extract the block error rate (BLER) vs. SNR and utilize this for mapping the SNR into coverage. See this tutorial.
• You could make use of Matlab “RF Propagation” toolbox, (the ray tracing feature)
• You could make use of _siteviewer function in Matlab to show the location of the towers
• See 3GPP recommendations for NB-IoT design parameters (for the noise floor)
• Use Tx power of 10 watts at the UAV with an isotropic antenna gain 0 dBi
• Use frequency 2100

MHz         for         the

simulation

If something is not stated in the question use your own assumptions and explain the

reason for such selection

Suggest your own project!

There is also a possibility for you to suggest your own project. However, the following conditions apply:

• The project should be sufficiently related to IoT access networks
• The project should include significant coding (simulation) and novel contribution
• Should not be your Capstone project or a variation of your Capstone project
• Should submit a project proposal by week 7, the proposal (150-300 words) should include:
  • Expected deliverables o Methodology
  • Significance

Some directions are for other projects:

• Simulating the performance of NB-IoT network under interference from ISM band
• Modifying LoRa modulation to applied on acoustic communications, where IoT devices can communicate with each other acoustically.
• IoT over satellite access network (or system)

The project needs to be approved by the course coordinator in order to be considered as an alternative!
