求翻译：根据未知节点接收到的信任节点的信号强度值，利用式（3）计算未知节点与信任节点之间的距离，然后利用三边测量法等计算该未知节点的坐标。是什么意思？

According to the trust of nodes unknown node receives a signal strength value, using equation (3) calculate the distance between the unknown node and trust node, and then use trilateration method to calculate the coordinates of the unknown node.

Based on an unknown node receives the trust of the signal intensity value node, use (3) calculate Unknown nodes and trust the distance between nodes, and then use 3 edge measurement method, the calculation of the unknown node coordinates.

Trust node signal intensity value receives which according to the unknown node, use type between (3) computation unknown node and trust node distance, then the use trilateration law and so on calculates this unknown node the coordinates.

According to an unknown node Trust received signal strength value of the node, using (3) calculates the distance between the node and the trusted node is unknown, and then using the triangular measurements to calculate the unknown coordinates of the nodes.
