| 摘 要： | 提出分布式动态信道分配算法(DDCAA),该方法能在高密度WLAN/WPAN环境下大大提高每个用户的吞吐量,尤其在变化的不均匀的通信量条件下,解决由于有限的信道所带来的自身干扰问题.仿真表明:给定任意的通信负载分布及原始信道分配,算法会快速收敛到平衡状态,整个网络的吞吐量得到了很大的提高.该算法能够根据信道的使用状态自适应的改变算法启动门限,并且只通过AP自身完成动态信道分配算法,真正解决了高密度WLAN/WPAN环境下的自身干扰问题,简单有效并有很高的实用价值.

| Abstract: | A distributed dynamic channel allocation algorithm(DDCAA) is pressented,which can improve per-user throughput significantly in dense WLAN/WPANs.It can solve self-interference problems caused by the deficiency of communication channels,particularly for nonuniform traffic conditions.From simulation results we can see that,given any traffic load distribution and any initial channel allocation,the algorithm can converge to an equilibrium state in a short time,and the overall throughput of the network is significantly improved.The proposed algorithm can change its threshold self-adaptively and has significant practical value due to its simplicity and effectiveness. |
