Hi Daniel,
However, the ratio computing vs communication in IoT is quite
impressive and there is a high interest in compressing frames before
transmitting them.
- Computing ranges from 0.5nJ per instruction for extremely
energy-efficient microcontrollers (such as CoolRisc or MSP430) to 200
nJ per instruction for high-performance microprocessors (such as
ARM9).
- Communication: from 100nJ to 1uJ per bit transmitted or
received, depending on modulation complexity and transmission power
(we only consider "low-power" radios, with transmit powers lower than
about 10mW).
Roughly speaking, this means that, for the energy cost of exchanging 1
bit, our system can alternatively compute 10-100 instructions.
Yes, it's impressive. Did you consider using ROHC (RObust Header
Compression)?
It will allow you to significantly decrease size of TCP/UDP/IP headers.

Valery Smyslov.
