The effect of receiver collisions on throughput performance of multichannel multiaccess protocols

The problem of receiver collisions in multichannel multiaccess communication systems consisting of parallel broadcast channels all of the same capacity is studied. An analytic solution is developed for the throughput performance assuming a receiver buffer with the capacity of one packet. We calculate the average rejection probability at the packet destination in order to estimate the effect of receiver collisions. The evaluations are carried out for multichannel slotted ALOHA-type protocols with Poisson arrivals and a finite population, examining the throughput degradation due to receiver collisions. Also, numerical results are included showing the throughput reduction as it compares with the case of a protocol without receiver collisions
