TinyOS 2.x,,,cc2420: For cc2420, i just calculated the time interval between consective messages :
---- MONO-- 113 ---- MONO-- 103 ---- MONO-- 97 ---- MONO-- 88 ---- MONO-- 82 ---- MONO-- 73 ---- MONO-- 66 ---- MONO-- 57 ---- MONO-- 51 ---- MONO-- 42 ---- MONO-- 36 ---- MONO-- 27 ---- MONO-- 20 ---- MONO-- 12 MONO is basically a monolythic preamble i.e in sendDone i immediately send another message. MONO is followed by the remaining time of preamble timer. The transmission time (gap b/w send and sendDone) toggles between 10, 6,9 and 7. so its a random number by just having a first look. I just want to minimize this time,,,i mean to say that if i am sending a packet with CC2420Transmit i expect it to immediately send to the radio (message buffer) without waiting (Backoff). I tried to do so by setting Congestion backoff and Initial backoff to 0, and also CCA to False, still there is not effect. can i really reduce this time interval ? Thanks a lot Obaid
