Memory fragmentation is caused by a combination of the allocation strategy used by the memory allocator, the sizes and alignments of the internal data structures, combined with the memory allocation behavior of your software application. A common misconception is that adding more physical memory will solve the fragmentation problem, instead it only means that it takes longer for the problems to be asserted.
Tackling the fragmentation problem is crucial for the 5G and LTE software as fragmentation problems may severely affect the service. Fragmentation problems are a well-known problem in LTE, but they can also be observed in newly deployed 5G systems.
In the context of this master thesis, you need to study and define techniques for how to detect, analyze and classify the memory fragmentation issues. It’s also crucial to be provide a clear visualization of the detected fragmentation problems in order to address and track the issues.
The following steps are envisioned as part of the thesis work:
· Identify the allocation patterns and propose a visualization method.
· Propose metrics for detecting fragmentation based on different factors and system parameters (like amount of traffic in the 5G application, number of connected users, etc …).
· Analyze and classify the fragmentation based on the factors and parameters.
· Verify and test the visualization with 5G and LTE software.
This project is targeting students in electrical engineering, computer science and computer engineering.
