Is high-speed wireless network traffic self-similar?

It has been well established that high-speed wireline traffic exhibits self-similar behavior. We study the propagation of self-similarity as wireline traffic is sent through a gateway to a wireless network. We employ a commonly used model for buffering and repacking performed at the gateway, and study the statistics of the output traffic. Both analysis and simulations reveal that the buffer system can produce traffic that has different degrees of self-similarity as compared to the incoming traffic, or even traffic that is no longer self-similar.
