文中针对WLAN中普遍存在的干扰问题及现有WLAN干扰监测和避免方法的不足,提出了分布式动态干扰检测和避免新方法,该方法无须中心集中控制器的干预,各被干扰的AP只需根据自身所处的环境合理地选择切换信道,将干扰的影响局限在一个很小的范围。特别适用于AP密集,严重干扰的情况。并通过实例验证了该方法的正确性。 Aiming at the common interference problem in WLAN and the shortage of existing WLAN interference monitoring and avoiding methods, a new method of distributed dynamic interference detection and avoidance is proposed in this paper. This method does not need the interference of central controller, and each interfered AP needs only According to their own environment reasonable choice to switch the channel, the interference limited to a very small range. Particularly suitable for AP-intensive, serious interference. An example is given to verify the correctness of the method.
