WebJul 19, 2024 · Diversity SA (DSA) is an enhanced variant of SA, which introduces a burst repetition to yield a slight throughput enhancement at low normalized loads respect to SA . A more efficient use of the burst repetition is provided by a new contention resolution diversity slotted Aloha (CRDSA) . WebConcerning slot-based random access techniques, Slotted Aloha (SA) [1] [2] and Diversity Slotted Aloha (DSA) [3] are used indeed in satellite standards [4] [5] whenever small amounts of data need to be sent. Deﬁning G as the nor-malized average number of packet transmissions per slot (namely MAC channel load), SA reaches a peak throughput
