Priority-based random access scheme for S-PCN

A novel random multiple access technique, priority-based fast access (PBFA), is proposed by the authors to reduce the access delay of delay-sensitive random access (RA) packets in S-PCNs. The approach, based on the concept of good channel transmission (GCT) , can significantly improve the delay performance, in particular, for those delay-sensitive packets, of a slotted ALOHA (S-ALOHA) random acces…
