Developing of Network Mobile Application

Nowadays the mobile devices are becoming more and more popular. Most of the phones have some kind of hardware which makes the phone capable to use wireless network connection. Now we are able to surf on the internet with our mobile phones. Not only had the networks evolved, but also the handset hardwares, too. For example the mobile devices have much larger screens and they are easier to use than the older phones. But what could we do with our smart phones if we do not have good software which can harness the abilities of the device? That is why we need to care about the question of developing applications for mobile phones. In this paper a Network Mobile System is introduced. We focus on the architecture point of view of developing mobile applications which uses network connections. Some interesting solutions will be introduced, with which the application can use a central database. The mobile devices do not have an own IP address yet so they can not connect directly, but we will show a way with which the phones will be able to communicate with each other. The document will introduce the solutions through an example Interactive Mobile Forum application.
