ENG233 Internet of Things (IoT) Jan 2024 Presentation GROUP-BASED ASSIGNMENT This assignment is worth 15% of the final mark for ENG233 Internet of Things (IoT). This is a group-based assignment.

You should form a group of a maximum 4 members from your seminar group. Each group is required to upload a single report via your respective seminar group site in Canvas. Please elect a group leader. The responsibility of the group leader is to upload the report on behalf of the group. In your 1-page cover sheet, please include the names and SUSS student PI numbers of all group members who have contributed to the completion of this project. Students will be assessed on their project design solutions, implementation, and report requirements. The material references for this assignment can are study units notes and references provided in the study units. You should review these materials before beginning the assignment. You may also find it necessary to perform additional research in order to provide better answers to the questions. 1. Introduction To build a good IoT solution, a good solution architect needs to have the fundamental understanding of how to identify and define the real business and operational problems. How to prioritize them for the benefits and impact. In the process of designing the solution, architect shall then break down the problem into various technical stacks of the IoT solution, and then solve the entire problem from the end-to-end workflow perspective. This GBA aims to give students an opportunity to identify and articulate an IoT problem, and how to evaluate various components to solve the problem. The students will apply their knowledge acquired in the classroom primarily in the areas of sensors and devices, connectivity and communications protocols, cloud, fog and edge computing on an agriculture problem to justify their solutions to meet design requirements, which will guide the implementation of various components of the solution. 2. Learning Objectives The GBA provides learning objectives in identifying and defining the problems, applying design thinking and system thinking, evaluating and selecting various sensors, communication protocols and computing technologies. In this process, students will be able to extend their learning experience to designing a real-world application, a Location Intelligence IoT Solution. Page 2 of 5 3. Project Description IoT has applications in all industries. National Public Hospitals (NPHs) in Singapore need to track their patients, and utilization status medical equipment for operational efficiency, emergency response, optimization of services, and management of resources. National Public Hospitals (NPHs) is looking to create an IoT enabled patient tracking system from check-in to check-out, and an intelligent equipment monitoring system. Patient Tracking and Equipment Monitoring System (PTEMS) There are 5 NPHs across Singapore. Each NPH serves between 100-200 patients of which 10- 20 patients are hospitalized. Each NPH needs to track their patients' location within hospital campus seamlessly from registration to check out, including their hospitalization period. NPHs also need to monitor patient's critical vitals to address any emergency scenario. NPH have medical equipment which needs to be shared among patients during hospitalization period. NPH needs to track the equipment location and utilization status to plan the allocation. Report format The GBA report should present answers in accordance and meet the requirements as stated in the questions. All answers should be explained with reference where necessary. 4. System Specifications The digitalization team at NPH is looking to build PTEMS to meet following expectations: 1. Be able to locate all patients within an accuracy of 3 meters in the hospital campus. 2. Be able to track the dwell time with location and time stamp of patients. 3. Be able to monitor patients' vital stats (Heart Rate, Blood Pressure). 4. Be able to locate all medical equipment within an accuracy of 3 meters and utilization status (status and duration of utilization as per allocation). 5. Solution Design Approach The Solution will be designed in 3 key steps. 1. Design the system model based on the operational flow. 2. Identify potential components in each solution stack. (Sensors, Connectivity, Computing) 3. Evaluate and select right components, evaluate technical integration, and finalise the best fit end to end solution. Page 3 of 5 6. Report Requirements The project report should include suggestions and justifications given with respect to the solution design and implementation requirements. 1. Define the requirements by designing the operational workflow and by answering the following: (a) Plan and draw patient journey workflow AND medical equipment management workflow "without" PTEMS in place. (Description: 10 marks, workflow diagram: 10 marks. Total 20 marks) (b) Identify at least 4 key operational problems that can be addressed by PTEMS. Propose and apply a ranking methodology/rubric to prioritize the problems. (Description: 10 marks, Ranking Rubric: 10 marks. Total 20 marks) 2. Identify, recommend and provide information of at least TWO (2) options each in the solution component selection matrix. Describe why you consider them as potential options. Feature Type of sensors to Type of connectivity Type of computing capture the data & communication infrastructure infrastructure to transfer the data Locate all patients 1. within an accuracy of 2. 3 meters. Dwell time with location and time stamp of patients Locate all equipment 1. within an accuracy of 2. 3 meters. Utilization Status of 1. all equipment. 1. 2. 1. 2. 1. 2. 2. 1. 2. 1. 2. 2. 2. 1. (Each option: 1 mark, Total 24 marks) Page 4 of 5 3. Evaluate options identified in Question 2 and provide valid technical reasons to propose ONE(1) best fit option that you would proceed with to build ITOS. Feature Locate all patients within an accuracy of 3 meters. Dwell time with location and time stamp of patients Locate all equipment within an accuracy of 3 meters. Utilization Status of all equipment.
