Analysis of dynamic channel assignment with queuing and guard channel strategies for handoff prioritization
Xiaoming Ma · Journal of Shenzhen Polytechnic · 2004
The performance of dynamic channel assignment with queuing and guard channel strategies for handoff prioritization (DCA-GC-QH) are examined. By using the M/M/M/T Makov chain model, closed form expressions for the call blocking probability (Pb) and the handoff failure probability (Ph) have been proposed and evaluated respectively. In comparison with the guard channel and queuing strategies in fixed channel assignment for handoff prioritization (FCA-GC-QH), the Pb and Ph for the DCA-GC-QH scheme are reduced by more than 20% and 30%, respectively. In addition, the analytical results keep in line with its simulation.
