VIDEO TRAFFIC MODELING IN HSDPA NETWORK SIMULATION

摘要

In this paper, we analyse streaming video traffic characteristics and the benefits of modeling streaming traffic based on trace files. We describe in detail an OPNET-based video traffic generator that reads video trace files and generates video packets as inputs to an HSDPA network simulator for purposes of evaluating network performance. We then briefly present simulation results regarding video jitter buffer sizes in HSDPA systems for different video encoding, bit rates, radio conditions and network settings.
