omnet++ delete a module element

I need to delete sensor node if its energy level is less than 0.Every sensor nodes has inout gate.Every sensor node is also connected to the LCN.LCN has inout gate. I wrote this code to delete the module.

if(totPower<0){
       deleteModule();
       callFinish();
    }

it works but If another request is came to this lcn to sensing data, Lcn assume this deleted sensor module is still connected to it and throws connection error.How can I solve this problem?By the way I am using just Omnet++, not inet,castalia etc.

<!> Error in module (LCN) Network.lcn[7] (id=254) at event #188, t=1200: send()/sendDelayed(): gate `lcnSN$o[11]' not connected.

First of all, you should change declaration of connection in your network NED into:

connections allowunconnected:

It allows gate to be left unconnected.
Secondly, callFinish() should be involve before deleteModule().
Moreover, you have to check whether a gate is connected before sending through it. Sample code:

    // i - is an index of gate lcnSN you want to send
    cGate *outGate = gate("lcnSN$o", i);
    if (outGate->isConnected()) {
        send(msg, "lcnSN$o", i);
    }

The suffix $o means an output part of the gate.
