WLC47-5: Modeling Wireless TCP Connection Arrival Process
Ian W. C. Lee, Abraham O. Fapojuwo · Globecom · 2006
Ensuring quality of service (QoS) for high bandwidth applications over wireless networks is a challenging research problem. Accurate modeling of the wireless TCP connection arrival process aids in designing QoS algorithms. In this paper we perform an extensive statistical analysis of collected wireless TCP connection arrival process. Unlike wired TCP connection arrivals which are readily modeled as a heavy-tailed Weibull renewal process, we show that more sophisticated models are needed for wireless. Our proposed model, a multinomial canonical cascade with 3 stages, is able to capture the long- range dependent and multifractal characteristics of wireless TCP connection interarrival times. In addition, the model gives good approximation to the packet loss rate of measured wireless traffic trace.
