ANGELA is an HTTP adaptive streaming and edge computing simulator that was developed to address limitations of other simulators. It focuses on video streaming and edge computing mechanisms. ANGELA imports real radio traces or data from NS-3 for accurate wireless simulations and reduces simulation time. It also simulates various adaptive bitrate algorithms located at the client, edge, or server. ANGELA provides metrics to evaluate streaming quality and supports custom video datasets and machine learning techniques. The developers hope to publicly release ANGELA to evaluate new adaptive streaming and edge computing approaches.
