Abstract :
Dual channel operation of an optimum channel utilization multiaccess (DC-OCUM) protocol using the busytone concept for fully connected and homogeneous broadband wireless LANs is considered. The DC-OCUM protocol uses two independent message and busytone channel pairs. The message channels are synchronised slotted channels with slot size equal to one packet duration and the busytone channels indicate the idle or busy condition of the respective message channels. Two variations of the arrival process, one without explicit rescheduling and the other with a retransmission probability for rescheduled messages, are considered. The throughput performance of the DC-OCUM protocol has been estimated through a simulation model for Bernoulli arrival process and geometric distribution of message length measured in number of packets. The performance of the protocol under two different channel selection policies are evaluated and compared
