| Abstract | The optimal CAC in a wireless network is studied and compared with nonprioritized and fixed guard bandwidth scheme. The optimal policy used in the scheme to decide whether to accept or reject the call depends on the discount factor ( /3 ) and the reward per accepted call ( r; ). Cases with one or two types of CBR and VBR traffic, with bandwidth requirements of 1 to 8 bandwidth units, are considered in the simulation. The wideband customers and handover calls are protected by allocating them higher reward per accepted call. The performance of the system is evaluated in terms of new call and handover call blocking probability, bandwidth utilization and carried reward based on Monte Carlo simulation. The results show that the perfo1mance of the optimal CAC and nonprioritized scheme is equal when the value of discount factor f3 or the reward per accepted call is low. On the other hand, the optimal CAC gives a higher performance than the nonprioritized scheme when f3 or r; is high. |
