I am trying to implement jamming signals using iris motes with mib520 chip. My 
goal is to completely block other nodes' communication. In the program, I 
broadcast a node ID using AMPacket. The ID is sent non stop by put a send 
signal in the sendDone event and CCA has been disabled. Then I used Basestation 
to monitor the traffic. It seems that most of the time, my program wasn't able 
to block other traffic. There were very few collisions. 

My questions are:

1. Are there any other things I need to do besides sending non-top and disable 
CCA in order to block all other traffic?
2. Is it possible to send tones on mib520? If so, could someone point a light 
how?
3. I remember seeing RF230Sniffer before, but couldn't find it after searching 
the entire tinyos folder. Would someone point me the direction please?

Thanks in advance.
