摘　　要：针对传统文件传输系统需用户进行繁琐的搜索、配对及连接导致建立连接耗时长的问题,提出了一种采用近场通信(Near Field Communication)传输设备参数辅助建立设备Wi-Fi Direct快速连接的方法,该方法减少了建立连接所需时间和功耗.系统基于模块化思想设计了无线通信、数据传输和人机交互等功能模块,采用Wi-Fi Direct点对点无线通信方式,建立了基于TCP的Socket网络通信,实现了在较远的距离以较高的速率传输数据的功能.经验证,传输系统的连接时间和传输速率具有明显优势,稳定可靠,具有良好的用户体验.In view of the problem of the long time needed to establish connection among traditional file transmission systems that is caused by the fussy operations of necessary search, match and connection of the users, this research proposed a method based on NFC transmission equipment parameters to help establish a Wi-Fi Direct connection. The method reduced the time and power needed for the connection establishment. Based on the thinking of modularization the system designed such founction modules as wireless communication, data transmission, human-computer interaction and so on. It used Wi-Fi Direct point to point wireless communication and established Socket network communication based on TCP to realize the function of data transmission in further distance at a higher speed. The transmission system was verified to have obvious advantages on the time of establishing connection and the speed of transmission. Moreover, the system is stable and reliable and has good user experience.
