Traffic model of WAP over GPRS

Based on the real WAP trace collected on GPRS network, a novel WAP model is put forward in this paper. This model is composed of 3 layers - session, transaction and packet. And the packet is divided into signaling packet and service packet, because they are comparable in size and quantity but have different characteristics in distribution. The self-similarity of real trace and that of the trace generated by this model captures the characteristics of real WAP traffic.
