Editing Contiki (section)

==Low-power operation==
Many Contiki systems are severely power-constrained. Battery operated wireless sensors may need to provide years of unattended operation and with little means to recharge or replace batteries. Contiki provides a set of mechanisms to reduce the power consumption of systems on which it runs. The default mechanism for attaining low-power operation of the radio is called ContikiMAC.<ref>{{Citation |title= The ContikiMAC Radio Duty Cycling Protocol |first= Adam |last= Dunkels |url= http://dunkels.com/adam/dunkels11contikimac.pdf}}.</ref> With ContikiMAC, nodes can be running in low-power mode and still be able to receive and relay radio messages.
