Receiver xbee receiving data while the Transmitter is powered off?

Question

My receiver xbee is receiving data even if the transmitter is disconnected , so if i am sending the string hello world , the receiver will repeat this string .

void loop() {
    Serial.println("Hello");
    delay(1000);
}


void loop() {
     if(Serial.available()>0){
         Serial.print((char)Serial.read());
     }
}

As @Garben mentioned, we do not know what is your question, problem or whatever... Provide some more information about wiring. I looked at your question 5 mins and still can't get what is wrong...

What are you doing here??? Sending from Arduino+XBEE to another Arduino+XBEE???

void loop() {
    Serial.println("Hello");
    delay(1000);
}

Here you are resending what you got

void loop() {
     if(Serial.available()>0){
         Serial.print((char)Serial.read());
     }
} 

So what is your problem? Or is this all your code??? Arduino has to have

void setup(){
//Set up your Arduino here
}
void loop(){
//Code here will run over and over and over...
}
