Question 1

a. Health Monitoring System

The health monitoring system can be implemented in health care institutions through which it is possible to create a smart home where wearable and IoT-enabled devices collect information about daily activities and the physiology of its inhabitants. The edge-gateway-cloud pattern can be applied in the architectural elements of the system, which is effective for developing a smart home. An edge-gateway is a virtual router for the organization to develop a VDC network, and the network services include firewall, NAT, static routing, VPN, and balancing. The edge gateway can be created with the help of architectural development, allowing the organization to configure all settings. Edge cloud architecture is a cloud-based distributed system used to maintain activities in care homes for monitoring purposes. The Internet of Things (IoT) is also instrumental in developing elements for creating a system to track daily activities. The software functions play an important role in each tier, managing inputs effectively to produce the desired outputs. This system is developed through careful planning, managing a talented team, and collaborating with project team members.

b.The core requirement of the Internet of Things is asset identification, capable of providing proper services to clients. EPC, uCode, and OID are effective systems for adopting a hierarchical code structure. This structure encourages modularity and provides a proper framework for coding and management, making it preferable to a flat structure. uCode is used to identify individual objects, issuing codes to manage the structure and framework for better performance and tracking. OID structures the system and develops suitable computerized systems to monitor daily activities. Thus, a hierarchical structure is beneficial for developing cloud computing systems where wireless systems and technological infrastructure aid software developers in creating software to manage activities and develop smart homes. The health monitoring software helps organizations track health-related outcomes, using daily tracking systems to monitor individuals' conditions while ensuring data safety and security. The hierarchical structure in IoT and software services is essential for understanding and tracking health care systems effectively.

Question 3

a. GPS (Global Positioning System) is a satellite-based radio navigation system owned by the United States government and operated by the United States Space Force. It is effective in tracking the position of individuals and identifying required locations. However, in dense urban settings, GPS receivers' accuracy diminishes. The main cause of performance loss is satellite signal blockage due to high buildings, trees, and bridges. Urbanization factors such as tunnels, high building constructions, trees, and mountains obstruct satellite signals, reducing GPS system efficiency. Additional factors like satellite geometry, atmospheric conditions, signal blockage, and receiver design/quality also negatively affect GPS performance, diminishing its accuracy.

In the era of technical advancement, other options for tracking locations using smartphones exist when GPS fails. Alternatives like PinMe allow individuals to track locations without GPS, even if Wi-Fi is off. Smartphone users can manage applications to track locations, using tools such as Google History through Google Maps, the Smartphone time zone tracker, and sensor information. If connected to a Google account, locations can be tracked via Google location history and timeline. However, alternatives like PinMe have limitations, such as dependence on air pressure readings and elevation/weather conditions. Other drawbacks include data loss, inaccuracy in Google history, and internet loss, which affect location tracking accuracy. While GPS is an efficient tracking method, alternatives like PinMe and Google history/timeline offer backup options, despite their limitations.

Question 4

a.The college plans to develop an indoor localisation system to track students in the Malet Street building. This system will use a smartphone application to track students successfully within the campus. The system should include a proximity sensor and appropriate code to track students. Web mapping tools, such as GPS and Google Maps, are essential for students to share their locations with the college authority. The college should also develop a Wi-Fi-based positioning system (WPS), which functions even when GPS is inaccurate. Through WPS, students can be tracked effectively by the authority. Wireless access points and signaling are crucial for developing WPS, enabling the college to create an indoor positioning system for tracking students. This wireless communication system will allow students to share their location using appropriate technology.

b.The capabilities of WPS, GPS, and telecommunication systems are crucial for users to share their locations accurately. Students can manage smartphone applications to share their locations without obstacles. The college must invest in financial resources and technological advancements, including Information and Communication Technology (ICT) and the latest IT framework, to develop the system for tracking students efficiently.

c.Consumer privacy is a major factor in developing the system. The college should implement a cloud computing system to protect gathered data and information about students, complying with the General Data Protection Regulation (GDPR) 2018. The cloud system will manage student data safely. Data can be stored automatically using WPS and GPS, ensuring proper management. The college must invest significantly in developing the indoor positioning system, creating WPS, and developing the smartphone application to benefit students on campus. Technicians must protect gathered data and track students around the campus accurately using timelines and location data.
