can you explain your point as i am new in this field but i want to do this..my basic aim is to send a snapshot to a smart phone which i have taken by IP camera..is there any way to do this thing by Arduino mega 2560?
Ip camera needs a network or wifi connection for transmitting the image..i am using GSM module (SIM 900D) in my project with arduino mega 2560 for sending that image....
can i use ethernet shield (enc28j60) for sending this image to a smart phone?
if yes what will be the coding..i need a prototype please reply
Rather than trying to make those components work together (which I doubt you will manage) I think you would be better off just buying an Ethernet/3G adapter. They are certainly available - that's basically what MyFi is - but if you don't need the WiFi part then perhaps you could find a 3G modem with an Ethernet interface that is cheaper.
If you can't find one within your budget then the next option would be to use an ordinary DSL/cable router with 3G modem support.
The option of basically making your own router using an Arduino I don't think is feasible and is certainly not sensible.
thanks for replying PeterH
but it is the limitation of my project that i cannot use modem...i have to transmit MMS through GSM module (SIM900D)..is it possible?

I don't know where that limitation comes from, but if you have been set a challenge to implement it then you have to suppose that it is possible and that you are expected to know (or be able to find out) how to do it.
zoomkat:
With an Ethernet shield, the arduino probably could be used somewhat like an echo interface between the IP cam and some other device.
I don't think that the arduino's Ethernet shield can be used as a network router so it would not work.
I often echo out to the serial port what is received from an http get request as a debugging tool. it is probably possible to have the arduino request an image from the IP cam and send the received image data out the arduino serial port. No network router functions involved.
