... mechanism for the IEEE 802.11 and the IEEE 802.16 networks to share the same medium with adaptive resource allocation. Based on the mechanism, an optimized resource allocation scheme is proposed for ... throughput performance for the scheme without using priority. the AP becomes the bottleneck for the communications in IEEE 802.11. For the scheme without cooperation, we fix th...
