Testing Smart Smoke Detectors Under Simple Network Disruptions

Objective:

This Bachelor’s thesis investigates how smart smoke detectors behave when their network connection is disturbed. The main goal is to check whether basic fire detection and alarm functions still work under simple network-related issues.

Potential Work Packages (not exhaustive):

• Set up one or more smart smoke detectors in a simple test environment (devices provided)
• Learn how the devices communicate (e.g., via app or cloud)
• Simulate basic network disruptions (e.g., turning off Wi-Fi, blocking internet access, jamming)
• Test how the devices respond in a simulated fire situation while the network is disrupted
• Check if the app gives warnings or logs about the problem
• Document and summarize the results

Optional Extensions (depending on time and interest):

• Try out other types of disruptions (e.g., overloaded Wi-Fi)
• Compare different devices

Note:

This topic is well-suited for students with an interest in IT security, embedded systems, and networked devices in real-world use cases. It is strongly recommended that students have prior experience with networking and embedded systems — for example, through successful completion of courses such as Embedded Systems Architecture. Basic familiarity with system-level analysis and protocol behavior will be beneficial.
