Abstract
This paper considers queuing performance of a multipacket reception (MPR) slotted ALOHA channel with a finite population of terminals having infinite buffers. Each terminal retransmits its packet based on an exponential backoff algorithm upon a collision. By assuming that terminals’ interactions are statistically independent and identically distributed, we obtain an approximate lower bound of terminals’ queuing performance. However, numerical results of queuing performance show poor agreement between analysis and simulations. This is attributed to the positive correlation among the terminals’ interactions.
