A Low-Power CoAP for Contiki

2011 IEEE Eighth International Conference on Mobile Ad-Hoc and Sensor Systems, 2011
Internet of Things devices will by and large be battery-operated, but existing application protocols have typically not been designed with power-efficiency in mind. In low-power wireless systems, power-efficiency is determined by the ability to maintain a low radio duty cycle: keeping the radio off as much as possible.

Low power and high performance arithmetic circuits in feedthrough CMOS logic family for low power applications

, 2006
This paper presents the design of low power high performance arithmetic circuits using the feedthrough logic (FTL) 1 concept. FTL is ideally suited for the circuit design where the critical path is made of a large cascade of inverting gates.
