Abstract
In the context of IEEE 802.11 WLAN networks, enhancement to the Relaxed Deterministic Backoff (R-DEB) for random access of shared (Medium Access Control MAC) method. For all available candidate resource slots, a busy index is calculated that reflects the level of use/occupation in the past and infers a probability of use in the future by another concurring device. The method assumes the use of a sub-set of resource slots for transmission, and updates this set by replacing resource slots for which collisions are frequent with a not currently used candidate resource for which the busy index is the lowest. Passive Spoofing/overhearing of all resources for clear channel assessment (CCS) is used for resource monitoring purposes.
