Ad-hoc komunikační síť pro android

Abstract

This diploma thesis is a summary description of the Ad-hoc communication on the platform of operating system Android. Also this thesis describes the process of creating a sample application that enables secure and insecure text communication using in Android supported technologies Bluetooth and Wi-Fi Direct. Android using these technologies does not fully utilize Ad-hoc communication method. Bluetooth and Wi-Fi Direct generally allow communication only in groups and only between client and server. They contain no possibility of communication between clients. For both technologies on the Android platform, there are only the basic software tools that can be used and which contain some restrictions. These software tools cover the basic features of both technologies and also contain no implementation of communication between clients. Communication between clients must always be solved at the application level. The final application for Android operating system contains a separate text communication using implementation of software tools for Bluetooth and Wi-Fi Direct and basic possibilities of sending messages between clients. For application development is used a program Android Studio together with the latest version of developer tools.
