One master with 5 slave communication

I would like to know what device and model to use for an application where I will have 1 arduino as a master micro controller waiting to receive data from 5 slave arduino microcontrollers.

The Master arduino will be connected to local network via Ethernet cable so once it receive data from a slave controlller it needs to post to server the Informacion, get a response back and in case the response is a "true" value then the master need to send talk with the slave in order to turn a LED on.

There will be cases when maybe 3 of the salves will send data at the same time. So I don't know if there will be data lost.

I was reading that Xbee maybe is the best device because it has a feature that will hold the data until there is a success communication with slave.

Is this a doable and "easy" task using Xbee? Anyone that already try to do something like this?

Appreciate any advice or help. Thanks

Is wireless communication a requirement of the project?

If you need wireless communication then have a look at this Simple nRF24L01+ Tutorial. The nRF24 modules are cheap and work very well.

Jeez - don't ask the same question in two places.

Based on the little information you have provided I reckon the nRF24 modules will work. If you provide more detail it may be possible to give a better answer. In any case they are cheap enough to buy a few for testing.
