Chapter 2, Problem 2.1E
Explanation of Solution
A system to control anti-lock braking in a car:
- The most appropriate generic software process model for controlling anti-lock braking in a car is Waterfall model.
- The anti-lock braking is a safety-critical system.
- In the waterfall model, for the proper functioning of the anti-lock braking system of the car, the analysis and design requirements must be scheduled without any flaws before the system implementation.
A virtual reality system to support software maintenance:
- The most appropriate generic software process model for a virtual reality system to support software maintenance is Incremental development.
- The system requirements keeps on changing and it cannot be predicted before the implementation and it requires complex
programming for the software. - This software is not a critical system.
A University accounting system that replaces an existing system:
- The most appropriate generic software process model for a University accounting system that replaces an existing system is Waterfall model.
- Because of the existing system, the system requirements can be predicted.
- This is mission-critical system and the requirements are stable and reusable.
An interactive travel planning system that helps users plan journeys with the lowest environmental impact:
- The most appropriate generic software process model for an interactive travel planning system is the prototype model and incremental development model.
- The requirements of the user may change and fast delivery is essential to be implemented.
- Therefore, the prototype model will save the development time to focus on essential function first to be later completed.

1. Smart Home Automation:o Connect a temperature sensor and a fan to a home gateway.o Configure the home gateway so that the fan is activated when the temperature exceedsa set threshold (e.g., 30°C).2. WiFi Network Configuration:o Set up a wireless LAN with a unique SSID.o Enable WPA2 encryption to secure the WiFi network.o Implement MAC address filtering to allow only specific clients to connect.3. WLC Configuration:o Deploy at least two wireless access points connected to a Wireless LAN Controller(WLC).o Configure the WLC to manage the APs, broadcast the configured SSID, and applyconsistent security settings across all APs.
