Optimizing the Client/Server Communication for Mobile Applications Part 2
Part 2 of this white paper series explores the different transport protocols being used and compares them with each other. The working example shows how to build up a generic framework which isolates the protocol layer from the client application. This allows to optimize the transport protocol without the need to change the application itself.
Optimizing the Client/Server Communication for Mobile Applications Part 1
In addition to stand-alone applications running on mobile handsets without any need of interaction with external resources, there is a need for a distributed environment where the client needs to communicate with the server using an IP connection. Part 1 of this white paper series lays out the fundamentals for a general framework using web services or a proprietary protocol.
