A novel algorithm of channel resource allocation in wide band WLAN

With the development of Wide-band wireless communications, MAC protocol in IEEE 802.11 can''t satisfy user-individual quality of service (QoS) guarantees effectively and can''t support high speed mobility. A novel algorithm for channel allocation in Wide-band WLAN and an improved resource reservation mechanism applied into IEEE 802.11 MAC protocol are proposed in this article. The simulated results indicate that the advanced protocol makes the system throughput improved and delay decrease. Moreover, the improved system shows an excellent performance in the environment with high speed mobility.
