CHESTNUT: A QoS Dataset for Mobile Edge Environments
This dataset addresses the need for reliable data to improve QoS prediction in mobile edge computing, though it is incremental as it builds on existing datasets by adding dynamic features.
The authors tackled the lack of dynamic attributes like time and geographic location in existing QoS datasets for mobile edge environments, resulting in a novel dataset that accurately records these attributes to support more accurate QoS prediction.
Quality of Service (QoS) is an important metric to measure the performance of network services. Nowadays, it is widely used in mobile edge environments to evaluate the quality of service when mobile devices request services from edge servers. QoS usually involves multiple dimensions, such as bandwidth, latency, jitter, and data packet loss rate. However, most existing QoS datasets, such as the common WS-Dream dataset, focus mainly on static QoS metrics of network services and ignore dynamic attributes such as time and geographic location. This means they should have detailed the mobile device's location at the time of the service request or the chronological order in which the request was made. However, these dynamic attributes are crucial for understanding and predicting the actual performance of network services, as QoS performance typically fluctuates with time and geographic location. To this end, we propose a novel dataset that accurately records temporal and geographic location information on quality of service during the collection process, aiming to provide more accurate and reliable data to support future QoS prediction in mobile edge environments.
