A traditional traffic model for circuit switched data as well as packet data is the Poisson process in which the number of incoming packets per time is according to Poisson distribution. It is one of the most widely used and oldest traffic models. In this model the length of each packet is based on exponential distribution and the number of simultaneously ongoing packets is according to Erlang distribution [16]. The Poisson process is characterized as a renewal process. In a Poisson process the…
