Messages Sent simultaneously from more than 1 transmitters are not recived properly at reciever.

I am using this library and found it great at first sight, but i am getting into trouble when i have more than one transmitter. Sending data with different sender ids. But when i check in the reciever, many times i am not recieving messages from both the transmitters. It seem to drop few messages and i doubt if the no of tranmitter increases, no of dropped messages will increase even more ? Is there any solution for this problem in the library ? or am i doing something wrong. ?
