| Summary |
CDMA unslotted ALOHA system with finite size of queueing buffers is discussed in this
paper. We introduce an analytical model in which the system is divided into two Markov
chains; one is in the user part, and the other is in the channel part. In the user part, we
can model the queueing behavior of the user station as an M/G/1/B queue. In the channel
part, we can consider the number of simultaneously transmitted packets as an
M1+M2/D/infinity//K queue. We analyze the queueing system by using this analytical
model, and evaluate the effect of buffer capacity in terms of the throughput, the rejection
probability and the average delay. As a result, increase in the buffer size brings about an
improvement in the grade of service in terms of higher throughput and lower rejection
probability. |
