Hello,
I am trying to test the pure throughput of 802.15.4 and conduct
an
experiment as follows
should be: 3.84/(3.84+3.176)*250K = 136.8 Kbps 35
Kbps.
Am I missing any delay/overhead? Thanks.

Yes. Baud rate is bit per second. I set 115200 (115.2 Kbps) in my
experiment.
I got 35 Kbps (bit per second) throughput at receiver side.
since 35 is far smaller than 115.2, the bottleneck is not the
serial
port, it is in air-interface.
The MAC in the mote
As indicated on page 66 in cc2420.pdf, turnaround time is 192 us or 128 us, not
450us.

Hi Folks,
I have some Tmote connect and Tmote sky. I want to use sensor networks as a
bridge to connect two (or more) computers. I am considering the following two
approaches.
Method #1 – without Tmote connect
Connect Tmote sky #1 to PC #1. Connect Tmote sky#2 to PC #2. How to send
packets
