I have not found any specific information about this, so I'm asking here: Is there a defined packet structure? The original papers use a 30-byte packet, with a destination byte, handler byte, and 28 bytes of payload. Are there newer specifications?
Also, in the Wireless Sensor Networks for Habitat Monitoring paper (http://www.cs.berkeley.edu/~polastre/papers/wsna02.pdf), in section 6-1, the authors indicate that for a 10-bit ADC sample of a light sensor & packet payload of 25 bytes, it requires 72 packets to transmit (using 10 bit samples) or 116 packets (transmitting 16-bit integers containing the 10 bit sample). I do not understand this. Are multiple ADC samples being transmitted? Is there processing being done on the samples to create some kind of image over time? I don't understand why a 10-bit sample requires 14,400 bits (72 packets * 25 bytes * 8 bits). What am I missing? Thanks in advance!
