Abstract :
A class of distributed scheduling algorithms, Regulated Contention Medium Access Control (RCMAC), which provides dynamic prioritized access to users for service differentiation, is considered in this paper. In addition to WLANs, the basic concepts of RCMAC have applications in multihop cellular and ad hoc networks and emerging sensor networks. Furthermore, by regulating multiuser contention, RCMAC achieves higher throughput when traffic is bursty. In this paper, differential function with two special cases like weight proportional and old base regulation is presented. Arrivals at each user are bursty, generated using standard two-state Markov model and the multiplicative increase/decrease rule are employed.
