Module Based Self-adaptive Contention Resolution Scheme for WiMAX Network with Heavy Traffic
基于模数的WiMAX网络高负载自适应冲突解决算法

The latest wireless network access technology,IEEE 802.16 provides broadband Internet connection to user.However,it was found that the mandatory contention resolution scheme in IEEE 802.16 which is based on truncated binary exponential backoff algorithm can not run perfectly in most cases,especially when the traffic is heavy.A novel self-adaptive contention resolution scheme was proposed,which divides all Subscriber Stations into several groups according to the available transmission opportunities in each f...
