Wireless Personal Communications Performability Modeling and Analysis for Wireless Cellular Networks with Prioritized Handoff Scheme

Nowadays, both of network operators and regulators are concerning about adding new end user's features. These features may be added to future networks and current deployed ones. In order to achieve that, network performance as well as its availability must be taken into consideration side-byside for having a successful network operation. The process of coupling of them will be beneficial in the characterization process of wireless communication systems. This kind of wireless network assessment is defined as performability analysis. In this paper, a wireless network is modeled with break-downs and, multi-repair techniques. Unlike the previous studies, for such systems, an exact model and solution approach is used for the performability assessment, and handoff priority issues are considered together with multi-recovery channel availability issues. Numerical results have been obtained and presented for various performability parameters, such as mean queue length (MQL), new call blocking probability (Pb), and handoff forced termination probability (Pfh). The presented model investigates the deployment of handoff priority scheme, in conjunction with the different arrival rates for different system capacities. The obtained results are presented comparatively to validate the obtained system behavior.
