Counting the number of transmissions in TinyOS 2.x - tinyos

Question

I'm trying to implement an application in NesC able to count the number of transmissions performed along the simulation, however I'm facing many difficulties. No approach that I tryed works. Could anyone help me? this is my application:
module FloodingC {
uses {
interface Boot;
interface SplitControl as AMControl;
interface Timer<TMilli> as MilliTimer;
interface Receive;
interface AMSend;
interface Packet;
interface AMPacket;
interface RootControl;
interface PacketAcknowledgements as PackAck;
}
}
implementation {
message_t packet;
bool locked = FALSE;
uint16_t flag;
event void Boot.booted() {
flag = 0;
call AMControl.start();
}
event void AMControl.startDone(error_t err) {
if(err == SUCCESS) {
if(TOS_NODE_ID == 1)
call RootControl.setRoot();
call MilliTimer.startOneShot(1024);
}
else {
call AMControl.start();
}
}
event void AMControl.stopDone(error_t err) {
}
void sendMsg(){
floodingMsg_t* msg = (floodingMsg_t* ) call Packet.getPayload(&packet, sizeof(floodingMsg_t));
if(msg == NULL) {
return;
}
flag = 1;
msg->nodeid = TOS_NODE_ID;
msg->counter = 1;
call PackAck.requestAck(&packet);
if(call AMSend.send(AM_BROADCAST_ADDR, &packet, sizeof(floodingMsg_t)) == SUCCESS) {
locked = TRUE;
}
}
event void MilliTimer.fired() {
if(locked) {
return;
}
else {
if (call RootControl.isRoot()){
sendMsg();
}
}
}
event void AMSend.sendDone(message_t *msg, error_t error){
if (call PackAck.wasAcked(msg) == SUCCESS){
locked = FALSE;
}
else{
sendMsg();
}
}
event message_t* Receive.receive(message_t* msg, void* payload, uint8_t len) {
floodingMsg_t* newMsg = (floodingMsg_t* )payload;
if (locked == TRUE) return msg;
if(flag == 0) {
flag = 1;
newMsg->nodeid = TOS_NODE_ID;
newMsg->counter++;
call AMSend.send(AM_BROADCAST_ADDR, msg, call Packet.maxPayloadLength());
}
return msg;
}
}
Thanks

You can count them using a BaseStation sniffer (included in tinyos), or adding a sequence number on your transmitted packet.
