description: Theme of the final qualification work: âData transmission over a dynamically organized wireless local area network. Linux application."
This work is devoted to the development of an application that provides file transfer between computers running the Ubuntu 12.04 operating system and higher using Wi-Fi Direct technology. To achieve this goal during development, the following tasks were solved:
1. Development of application architecture.
2. Development of software running under the Ubuntu OS.
3. Testing the program.
4. Estimation of file transfer speed.
A multi-threaded application for transferring files over a dynamically organized wireless network WiFi-Direct between two devices running the Ubuntu operating system has been developed. The application provides the establishment and monitoring of the status of the connection via WiFi-Direct network, file transfer under the control of the sender and recipient, an estimate of the file transfer speed. Using the QTest library, 29 tests have been developed that cover the business logic of the application. The results of a study of the effect of the version of the Ubuntu operating system, the hardware of the network controllers, the file size and the distance between devices on the transmission speed showed that the main contribution to the change in speed is made by the mode of operation of the network controller and the distance between computers.
