| Abstract: | This paper analyzes the existing QoS guarantee system at MAC layer in Ad Hoc network. Based on the technique of DiffServ, integrated the EDCF mechanism of 802.11e with the improved backoff method, the dual-channel is used to achieve reliable QoS guarantee. The result of simulation proves that the scheme can improve the throughput of network and the quality of service for the real-time traffic. |
