Coursework Submission Requirements
- An electronic copy of your work for this coursework must be fully uploaded on the Deadline Date of Friday 08/04/2022 using the link on the coursework Moodle page for COMP1797.
- For this coursework you must submit a single PDF document. In general, any text in the document must not be an image (i.e. must not be scanned) and would normally be generated from other documents (e.g. MS Office using “Save As .. PDF”). An exception to this is hand written mathematical notation, but when scanning do ensure the file size is not excessive.
- There are limits on the file size (see the relevant course Moodle page).
- Make sure that any files you upload are virus-free and not protected by a password or corrupted otherwise they will be treated as null submissions.
- Your work will not be printed in colour. Please ensure that any pages with colour are acceptable when printed in Black and White.
- You must NOT submit a paper copy of this coursework.
- All courseworks must be submitted as above. Under no circumstances can they be accepted by academic staff.
The University website has details of the current Coursework Regulations, including details of penalties for late submission, procedures for Extenuating Circumstances, and penalties for Assessment Offences.
DETAILED COURSEWORK SPECIFICATION: This is individual coursework.
Mini-project: “Choosing the best LPWAN technology.”
Scenario: You are employed as a Solution Architect for Emerging Technologies in a leading IoT networking company. One of your main responsibilities is to architect and design solutions to meet functional and non-functional customer requirements. Your latest project is about IoT-based smart agriculture applications. You have been asked to architect and design a cattle health monitoring solution leveraging Low Power Wide Area Network (LPWAN) devices and protocols. The devices (equipped with sensors) are deployed through a collar that is attached to each cow and report data on the cow’s health (e.g. body temperature to predict the onset of disease). You have been provided with the following customer requirements:
- Ease of deployment – A quick deployment with minimal additional infrastructure. The data is transmitted consistently for years without needing costly, frequent maintenance.
- Extensive coverage – A consistent connectivity for the wide-area ranches. The real-time data on cow wellbeing and location is received at a gateway/gateways to monitor cattle.
- Cost-efficiency – Following the deployment, a return on investment (ROI) is received in less than a year through an increase in ranch productivity and efficiency.
Task 1: Propose two potential LPWAN solutions that can be used in the above scenario. Critically discuss why the two solutions were selected. Note: Your company is able to support Sigfox, LoRaWAN, NB-IoT and LTE-M.
[20 marks]
Task 2: For each of the three customer requirements (ease of deployment, extensive coverage, and cost-efficiency), critically discuss if and how each of the two proposed solutions satisfies the requirement. Your answer should include an explanation of which solution would be more beneficial for each of the three requirements.
[60 marks]
Task 3: Give a brief overview of two additional benefits that the customer would have if your proposed solutions were chosen.
[20 marks]
DELIVERABLES
The final output is a report maximum 2000 words long (excluding references). The discussion needs to be supported by appropriate references presented in the Harvard referencing style. There is a 20% penalty if the report does not abide by the rule of a length of strictly no more than 2000 words (excluding references).
ASSESSMENT CRITERIA
The precise marking scheme is included within the template of the paper and is repeated here for clarity:
Task 1: 20 marks = each solution x 10 marks Task 2: 60 marks = each requirement x 20 marks Task 3: 20 marks = each benefit x 10 marks
Each task needs to be supported by appropriate references presented in the Harvard referencing style.
