How to read and print all the receive messages of a sensor ?

[Doris-Khöler Nyabeye]

I have 4th sensors in my network. The sensors 1,2 and 3 send a message which content their position to sensor 4. I want to read and print each message receive by sensor 4. But I can't! I just have one value how can I do to have the 3 values.
Thanks
