A paper by Fabian Kaup, Florian Jomrich, David Hausheer, entitled “Demonstration of NetworkCoverage – A Mobile Network Performance Measurement App” was accepted for presentation at International Conference on Networked Systems (NetSys 2015). Optimizing the Quality of Experience (QoE) of mobile applications over cellular networks requires detailed knowledge of the underlying network and it’s performance. Parameters of interest are, besides the signal strength and availability of technologies, the Round-trip Time (RTT) and available throughput of individual cells at a given location. This information is generally not readily available. Therefore, an Android application measuring the cellular network performance was developed. This demonstration shows the NetworkCoverage App, being implemented to provide visual feedback of the measured network quality to the users, and sample the cellular network in an efficient manner to later support traffic scheduling improvements based on reliable data.
