HI, I'd like to ask your opinion about this idea we had at University. Our goal is to have a network of 10 to 15 sensors, energy is crucial so all nodes must work on 2 AA bateries.  Our idea is to turn on all network and send information, after that all network would be shut down, and then waked up with the microcontroller. what would be the disadvantages of this approach?

Any sugestion?

Thanks in advance

    Have you looked at DASH7? www.dash7.org.  Doesn't have the power issues you are experiencing with ZigBee, is much longer range, supports multi-hop and sensors, and uses the ISO 18000-7 standard used by the military.  Supports TI CC430.
