基于Android终端的Wi-Fi中继功能的研究和实现

Research and Implementation of Wi-Fi Relay Function Based on Android Terminal

如今Android手机逐渐成为市场智能终端主导,同时由于生产周期的不断缩短,导致大量闲置Android手机出现。为了对闲置Android终端加以利用,现提出一种技术手段,对闲置Android终端的WIFI底层进行技术改造,实现强制开启GROUP,并利用JNI技术实现API接口,最后通过下发路由表的配置,使其具有AP功能,并可以和其他STA设备进行连接、通信,实现了WIFI中继功能。这样不仅能够对闲置Android终端加以利用,又灵活解决了无线网络信号衰减所带来的困扰。

Nowadays,Android phone gradually dominate the market of intelligent terminal,At the same time,numerous of the idle Android phones appear which due to the shortening of the production cycle.Now propose a technical method to reform the underlying of the idle Android phones＇ WIFI function,Forced open GROUP,and use JNI technical to make an API interface,at last,change the configuration of Routing Table,make the Android terminal an AP which can connect and communicate with other STA equipment.In this way,people can not only reuse the Idle Android phone but also solve the problem which caused by the Signal attenuation of wireless network.
