基于Android设备的异构无线链路聚合软件

Heterogeneous Wireless Link Aggregation Software Based on Android Devices

由于人们对随时随地传输数据的需求日益增加,当前单一异构无线网络通信的低带宽和高抖动严重影响了用户对移动设备的使用体验,针对移动设备尤其是Android移动设备对异构无线网络链路聚合的实际需求,本文提出了一种在移动设备上将移动数据网络和WiFi网络两种异构无线网络进行链路聚合的实现方案.该方案基于应用层开发,跳过下层复杂的数据包封装过程,不改动移动设备的硬件配置.文中阐述了无线链路聚合的工作原理与设计思路,并在Android手机上进行编程实现与测试.测试结果表明异构无线链路的聚合方案能明显地提高网络带宽,提高文件传输速度.

Due to the increasing demand for data transmission anytime and anywhere,the low bandwidth and high jitter of the communication of a single heterogeneous wireless network seriously affect users’experience of mobile devices.Considering the actual demand of mobile devices for link aggregation of heterogeneous wireless networks,especially the demand of Android mobile devices,this study proposes a scheme to realize link aggregation of mobile data networks and WiFi networks,two heterogeneous wireless networks,on mobile devices.The scheme is based on the application layer development,which skips the complex packet encapsulation process of the lower layer and does not change the hardware configuration of a mobile device.In this study,the working principle and design idea of wireless link aggregation are described,and the program is implemented and tested on Android phones.The test results show that the aggregation scheme of heterogeneous wireless links can significantly improve network bandwidth and file transfer speed.
