怎么检测哪个节点丢失了

我设置了一个具有3个协调器的miwi pro堆栈，这三个协调器都使用相同的pan id和共享公共信道连接。一个泛协调器和3个协调器像网状网络一样连接，在任何给定时间，我也可以通过任何协调器和泛协调器访问协调器数据。所以，问题是，如果任何协调器由于某种原因而断开连接，那么该协调器的最后一次接收数据仍然通过其他协调器显示。我想要的是，如果任何节点丢失了连接，我就应该能够检测哪个节点丢失了。仲裁者已经失去了…？关于一些帮助。这里是我在代码中所做的，但是它对我没有帮助。“如果（连接表。状态。

    I setup a miwi pro stack with 3 coordinators, all the three coordinators are connected with the same pan id and shared common channel. 1 pan coordinator and 3 coordinators are connected like a mesh network, at any given time i can access coordinators data through any of the coordinators and pan coordinator as well. So the Problem is, if any of the coordinators drops connection due to some reason, still last received data of that coordinator showing up through the other coordinators.
what I wanted is, if any of the node lost the connection, i should be able to detect which node has lost..
SO how do find which coordinator has lost..? regards some help..

HERE is what i did in my code but its not helping me.
"if(ConnectionTable.status.bits.isValid)"
