Which protocol can be used for M2M communication in IoT?

Question

I am working on Contiki OS based platform development for IoT.I want to implement M2M in IoT.

Let say , i have one sensor and one switch.Now i want to trigger switch based on threshold of sensor readings.I can achieve this easily.But i want some solid M2M protocol , which can be easily used for binding multiple devices.IFTTT does the same thing from cloud.

So is their any proven protocol available for M2M in IoT.
