[phpuser123]

I am developing an client server application on mobile phone and I would really appreciate to get some comparisons between each of them ..

There is no such thing as better. Each of those protocols has very different features and they are all suited for different jobs.

To even begin to comment we would need a lot more information.

Also you should try answering this yourself, what do you think of those 3 communication mechanisms.
