[Tinyos-help] Packet loss problem

[Vijayant Bhatnagar]

Hi,
We are trying to simulate broadcast environment. Initially we have set
up 6 motes trying to send packet to "Master" Node. We have observed
that not all 6 motes are able to send the packet. Is it because of
backoff problem or some kind of fault with our implementation ? After
going through the tutorials, I could realize that there is exponential
backoff built in cc2420. In that case, do we need to implement ARQ
kind of situation to recover from packet loss.

Please help.

Thanks,
