【摘要】：当今社会的生活节奏越来越快,人们对手机的要求也越来越高。由于智能手机的种类繁多,功能也越来越多,使得文件的种类越来越多,文件的容量也越来越大,这样在多设备间的文件传输时候就会造成许多问题,如传输速率过慢、传输信号不稳定等。另外,目前市面上已有多种文件传输方式,如蓝牙、NFC. Wi-Fi等,但是它们或多或少存在一些缺陷,如蓝牙传输距离短且不稳定,NFC传输类型单一等。这些日常的文件传输方式大多都不能满足我们的日常需求,需要我们去寻求一种新的文件传输方式,使其能满足远距离稳定的文件传输功能,以及多类型、大容量的文件传输等功能。本课题通过研究Android平台的Wi-Fi Direct API接口,比较其与其他几种文件传输方式的优势,按照软件开发生命周期的需求分析、概要设计、详细设计、编码、测试的五个主要阶段,实现移动设备的文件传输。论文主要开展了如下几个方面的工作：1)总结了Wi-Fi Direct技术在国内外的发展现状,通过与蓝牙、NFC、Wi-Fi.云传输等其他文件传输方式的比较,总结出采用Wi-Fi Direct进行文件传输的优势；2)对Android Wi-Fi Direct API的研究与编码,并运用到本文论述的系统中；3)将本文论述的系统按模块进行设计和实现,并对每个模块所要实现的功能和向上层提供的接口进行详细的定义与实现,最终整合成本系统所实现的文件传输系统。本文阐述了支持Wi-Fi Direct技术的智能手机进行自动匹配、文件传输的系统的研究结果,对Wi-Fi Direct在Android平台上更多复杂的手机应用开发,以及Wi-Fi Direct技术在未来的移动智能办公、智能家居生活中的应用都有一定的指导意义。
[Abstract]:The pace of life in today's society is getting faster and faster, and people's demands on mobile phones are becoming higher and higher. Because of the variety of smart phones and the increasing number of functions, there are more and more kinds of files, and the capacity of files is becoming larger and larger. This will cause many problems in file transfer between multiple devices, such as the slow transmission rate. Unstable transmission signals, etc. In addition, there are a variety of file transfer methods, such as Bluetooth NFC. However, they have some disadvantages, such as short Bluetooth transmission distance and unstable Wi-Fi transmission type. Most of these daily file transfer methods can not meet our daily needs, so we need to find a new file transfer mode, so that it can meet the long-distance stable file transfer function, as well as a variety of types. Large capacity file transfer and other functions. This paper studies the Wi-Fi Direct API interface of Android platform, compares its advantages with other file transfer modes, and according to the five main stages of software development life cycle requirement analysis, outline design, detailed design, coding and testing. Realize the file transfer of mobile device. The main work of this paper is as follows: 1) the development of Wi-Fi Direct technology at home and abroad is summarized. The comparison of other file transmission methods, such as cloud transmission, summarizes the advantages of using Wi-Fi Direct for file transmission. (2) the research and coding of Android Wi-Fi Direct API, which is applied to the system discussed in this paper, is used to design and implement the system described in this paper according to the module. The function of each module and the interface to the upper layer are defined and implemented in detail. Finally, the file transfer system realized by the cost system is integrated. This paper describes the research results of smart phone automatic matching and file transfer system supporting Wi-Fi Direct technology, the development of more complex mobile phone applications on Android platform based on Wi-Fi Direct, and the future mobile intelligent office technology of Wi-Fi Direct technology. The application of smart home life has certain guiding significance.
