Abstract
As successive interference cancellation (SIC) technology has become a research hotspot recently, random multiple access protocols based on SIC such as contention resolution diversity slotted ALOHA (CRDSA) and irregular repetition slotted ALOHA (IRSA) are put forward one after the other. Although throughput performance for these protocols has been improved significantly. Yet the throughput will drop dramatically when the load increases gradually. In this paper, in order to get a higher throughput in the case of high load, we propose a slot assign algorithm with threshold based on IRSA to obtain a throughput T which is more than 1.
