Call Completion Probability with Weibull Distributed Call Holding Time and Cell Dwell Time

In this paper, we derive a simple closed-form expression for the call completion probability in a wireless cellular network under Weibull distributed cell dwell time and call holding time. The derived expression is given in terms of the Meijer-G function which can be easily evaluated by commonly available computer software such as Mathematica. Numerical results are presented to show that the call completion probability is very sensitive to changes in the shape parameter of the Weibull distribution when its value is less than unity (heavy tail region).
