Fractal Analysis of Intraflow Unidirectional Delay over W-LAN and W-WAN Environments
Dimitrios P. Pezaros, Manolis Sifalakis, Laurent Mathy · 2007
We have analysed unidirectional delay traces of a diverse set of IPv6 microflows routed over W-LAN and W-WAN environments. Using a number of time-domain and frequency-domain estimators we have examined the existence and intensity of long-range dependence in packet delay when viewed as time-series data. The correlation structures of packet delay on bulk TCP data path and UDP flows follow asymptotic decay while Hurst exponent estimates suggest from moderate to strong intensity (H → 1).
