The Contiki team has just released version 2.1 of the open source Contiki operating system for low-power, wireless, memory-constrained networked embedded devices that typically have as little a few kilobytes of RAM. The major highlight of this release is a unique energy profiling mechanism that measures where energy is spent, and how much energy that is consumed. This is extremely important when optimizing for low-power operation: to know where to optimize, one must first know where energy is spent. Other additions to the 2.1 release are low-power radio protocols that increase system lifetime from days to years, and improved data collection routing protocols.
