Research Methodology
Research gap analysis derived from 2 engineering papers in our local library.
The gap
The studies lack exploration of varying system parameters such as number of paths, users, and complexity in their respective domains.
Consensus across the literature
The papers collectively establish the need for broader parameter testing but leave open how these factors affect performance across different scenarios.
