Hybrid mixed handover for call blocking probability analysis in wireless ATM network

This paper focuses on the problem of congestion control in wireless ATM network based on new Hybrid Scheme proposed by the authors to solve the hand off/hand over problem in ATM-based PCN, which aims to give handover calls high priority over new calls. It presents a non-disruptive handoff protocol with dynamic channel reservation for wireless ATM networks. The analytical results are verified by a simulation study, which has shown that a non-disruptive handoff with dynamic channel reservation does achieve much lower blocking probability under high traffic load and significantly reduce the average waiting time during handoff. The improvement reflects remarkable reduced percentage of FTP due to handover failure, when we use our proposed Hybrid Scheme. Key words: Wireless ATM, network, call blocking
