Abstract: A first node A sends a first message to a second node B. The second node B sends a second message to the first node. A first elapsed time is measured from the beginning of the transmission of the first message to the beginning of receipt of the second message. A second elapsed time is measured from the beginning of the receipt of the first message to the beginning of the transmission of the second message. The second node B sends a third message to the first node A containing the second elapsed time. The distance between the first and second node A, B is calculated based on these elapsed times and a calibration count multiplier contained in the second or third message. A node may be moved within a wireless mesh network. Positional information about the node and distances to its neighbors is determined and transmitted to the network manager where it is stored.

Abstract translation: 第一节点A向第二节点B发送第一消息。第二节点B向第一节点发送第二消息。 从第一消息的发送开始到第二消息的接收开始，测量第一经过时间。 从接收到第一消息的开始到第二消息的发送的开始测量第二经过时间。 第二节点B向包含第二经过时间的第一节点A发送第三消息。 基于这些经过时间计算第一和第二节点A，B之间的距离，以及包含在第二或第三消息中的校准计数乘法器。 可以在无线网状网络内移动节点。 确定关于节点和与其邻居的距离的位置信息，并将其发送到网络管理器，在那里存储它。
