hi all.
I'm sorry if i send a lot of question to you,but I didn't find answers in my
researches....
My question is about transmission steps for cc2420 radio stack.
I think that this steps are:
1) initial backoff ( 1--->32 jiffies , about 0,3 ---->10 msec )
2) transmitting mote detects if the channel is in use
3) channel idle -----> send packet
channel busy -----> set congestion backoff ( 1--->8 jiffies, about 0,3
---> 2,5 msec) and return to point number 2)
4) waiting for hardware/software MAC aknoledgment for max 256 jiffies (
about 8 msec) as specificed in \opt\tinyos-2.x\tos\chips\cc2420\cc2420.h
OR
4) return to point number 1 ???
I'm wondering if this steps are correct or not....please send me your
opinion or a web document ( IEEE document, cc2420 datasheet, etc ) in which
there is
a description of this steps...
I saw cc2420 datasheet in
http://inst.eecs.berkeley.edu/~cs150/Documents/CC2420.pdf ( Radio control
state machine) , but i did not understand if the steps
that I wrote over there are correct or not .
thanks very much for your answers
bye salvatore
