Lightweight Protocols for Wearable Computers(eg.Lily)

Hi.
I am trying to identify a suitable lightweight protocol to run on wearable computers ( eg.Lily ) for communicating Black&White (low resolution) pictures to the server. Can someone suggest an appropriate protocol and the implementation of the same on Lily ?
Thank You

Do you need just a protocol? In that case specify the hardware you're running on. I guess you have nothing (no software, no hardware) at the moment but you take picture with an unknown hardware.

So specify what needs you have (how much data in what time frame must be transmitted, how much power is available, what distance must be bridged, etc.).

If you must transmit data the Lily is probably a bad choice and an ESP based solution will probably fit much better.
