Performance Sensitivity to Higher Order Moments of Call Interruption and Cell Dwell Times in Cellular Networks
In this paper, sensitivity of the first three standardized moments of both unencumbered call interruption time and cell dwell time on teletraffic performance metrics of wireless cellular networks is investigated. Mathematical analysis for obtaining system-level performance metrics is developed considering that cell dwell time and unencumbered call interruption time are phase-type distributed random variables. Numerical results allow us to quantify the extent by which system performance depends on first three standardized moments of both cell dwell time and unencumbered interruption time.
