说明：  在NS2仿真软件（2.28）下，实现802.11E的增强分布式协调接入机制（EDCA，包括CFB模式），TKN开发，具有公信力。无论是仿真验证，还是据此做改进算法都十分适合。
(In the NS2 simulation software (2.28), the realization of 802.11e enhanced distributed coordination access mechanism (EDCA, including CFB mode), TKN development, have credibility. Both the simulation, or to do to improve the algorithm which are very suitable.)
