Abstract :
We thoroughly analyze the performance of the slotted Aloha (S-Aloha) scheme as a channel access method for a hybrid demand assignment TDMA protocol for broadband wireless networks. The performance of such embedded S-Aloha (ES-Aloha) is compared with the normal S-Aloha scheme, as a stand-alone scheme, and some useful results and conclusions are drawn. In addition, the importance of some performance measures for the channel access scheme is identified and their impact on QoS provisioning is defined. Moreover, the effect of call admission control (CAC) in the broadband wireless network performance is discussed and a general conclusion is presented
