IDENTIFYING STATIC LEAF NODES IN A MOTION DETECTION SYSTEM

In a general aspect, a motion detection system manages leaf nodes used for sounding by one or more access points. For example, an access point obtains presence information for a plurality of AP-leaf node links for a plurality of calibration periods. Presence activity is determined for each AP-leaf node link in each calibration period based on its respective presence information. Static leaf nodes are identified based on the presence activity for the plurality of AP-leaf node links in a calibration window, the calibration window comprising a number of the plurality of calibration periods. The motion detection system is updated to use at least one of the identified static leaf node as a sounding node for motion detection. 在一般方面，运动检测系统管理由一个或多个接入点用于探测的叶节点。例如，接入点针对多个校准时间段获得多个AP-叶节点链路的存在信息。基于各AP-叶节点链路各自的存在信息，在各校准时间段确定各AP-叶节点链路的存在活动。基于校准窗口中的多个AP-叶节点链路的存在活动来识别静态叶节点，该校准窗口包括多个校准时间段中的若干个。更新运动检测系统以使用所识别的静态叶节点至少之一作为用于运动检测的探测节点。
