Assessment of Channel Unavailability Effect on the Wireless Networks Teletraffic Modeling and Analysis

Authors: Eman S. El-Din, Hesham M. El-Badawy, Salwa H. Elramly


Whereas cellular wireless communication systems are subject to short-and long-term fading. The effect of wireless channel has largely been ignored in most of the teletraffic assessment researches. In this paper, a mathematical teletraffic model is proposed to estimate blocking and forced termination probabilities of cellular wireless networks as a result of teletraffic behavior as well as the outage of the propagation channel. To evaluate the proposed teletraffic model, gamma inter-arrival and general service time distributions have been considered based on wireless channel fading effect. The performance is evaluated and compared with the classical model. The proposed model is dedicated and investigated in different operational conditions. These conditions will consider not only the arrival rate process, but also, the different faded channels models.

Keywords: outage probability, Cellular wireless networks, traffic model, gamma inter-arrival distribution
