Design And Implementation Of Data Transmission Software Based On Wi-Fi Direct

The rapid development and application of wireless network technology has brought about tremendous changes in the mobile phone revolution.The relationship between mobile phones and people is getting closer and closer,and people's functional demands on mobile phones are also increasing.As the most common mobile phone application,transmission software also faces corresponding challenges.The existing transmission software such as Bluetooth,Wi-Fi,and QQ face to face,due to its excessive transmission restrictions,it is not enough to satisfy people's lives.Therefore,it is necessary to design data transmission software that does not require a complete network facility,greater transmission distance,and faster transmission speed.The dissertation mainly starts with the background research of the topic,researches and analyzes the status quo of the Android platform at home and abroad,investigates the use of transmission software at the current stage,and studies the status of Wi-Fi Direct by referring to various documents.The advantages and disadvantages of different forms of transmission software,such as Bluetooth search matching is relatively slow,transmission distance is short;QQ face to face,although the transmission is relatively fast but the transmission distance is very limited;fast transmission needs to be applied in the relatively complete structure of the network,and secondly From the background to obtain the significance and value of research,summarize the advantages of using Wi-Fi Direct transmission software,introduce the characteristics and usage of related technologies in the software,and combine the features and application scenarios of Wi-Fi Direct to the goals of the software.The analysis of the roles,the definition of the role model,the use-case model,the system flow,and other aspects,through the analysis of the requirements of the system,complete the design of the system module,including the UI design,the system design model and the detailed design of each function module and complete the basic idea of the software.In the function realization,according to the Android WiFi-Direct API,the device discovery and connection function of the software is studied and coded,and the functions of software transmission and history recording are realized based on the discovery and connection function,and the software implementation chapter Explained the main implementation methods,interfaces,etc.;test the software that has been implemented through testing,introduced the software testing environment in the test,and tested each function separately,and carried out the transmission distance and transmission speed in the non-functional test.Tests and compares the actual results with the theoretical results;Finally,it explains the inadequacies of the software and integrates the entire software through software engineering methods to achieve satisfactory results.This article elaborated the design and implementation process of Wi-Fi Direct data transmission software,and realized the basic file transmission on the smart device.The implementation of this system provides great value for the development of data transmission software on mobile devices,and provides a good reference for research based on Wi-Fi Direct.
