As the topic of my thesis I intended to choose either a field that deals with protocols in the application layer or with the production of media contents. Traversing the aforementioned two resulted in an application that approaches the typical, well known demands of people in social networks namely the sharing of their own media among the users within the same subnetwork. The most effective implementation for this is the support of broadcast with which we find ourselves in implementing our own protocol in the application layer based on protocols in the transport layer. My thesis is a great potential to scrutinize the communication between mobile devices and local servers as well as between mobile devices and remote servers via further protocols in the application layer gathering ground to remote controlling mobile clients from the local servers' side. Furthermore I present the co-operation of a contanier-server, a web-server and a database-server on the basis of database built up from the data of mobile clients and their indirect communication with remote servers via clients.
