[Tinyos-help] Amount of messages (broadcast-unicast)

[ndessart at martinique.univ-ag.fr]

Hello,

I tried a simple algorithm in wich all of my 20 motes broadcast a  
message after booting using TOSSIM and Tinyos 2.x.


- first case : "I just broadcast at the beginning" , and then each  
mote receive 19 messages

- second case : "A mote broadcast a message at the beginning, and if  
it receives a broadcasted message it replies using unicast", and then  
some motes receive only one broadcasted message (around 2 or 3) and  
some motes reply to a broadcast (2 or 3).


Notice that all my nodes are in the same radio range.

My question is : is it impossible to use such a amount of messages?
Do I have to write a algorithm to manage the channel access?

I think about , making my mote broadcast the initial message with a  
gap (using a random waiting time) but it didn't work fine.

some ideas?
