Newly Optimized RF24Network Layer
2014-2015 - Optimized RF24 Network Layer for NRF24L01 radios
Comparison to ZigBee

This network layer is influenced by the design of ZigBee, but does not implement it directly.

Which is better?

ZigBee is a much more robust, feature-rich set of protocols, with many different vendors providing compatible chips.

RF24Network is cheap. While ZigBee radios are well over $20, nRF24L01 modules can be found for under $2. My personal favorite is MDFly RF-IS2401.
