Splitting protocols in presence of capture

The effect of capture on splitting-type protocols in a slotted ALOHA broadcasting network is investigated. At first, it is assumed that the nodes of the network are divided into two groups, and only packets sent by nodes of one of the groups might be captured. The situation in which the receiver can distinguish between success slots and capture slots and that in which it cannot are both considered. For each of these situations, splitting-type multiple access protocols are described and their performance in terms of achievable throughputs is evaluated. Extensions of these protocols to a general capture model are also discussed.
