【摘要】：为了评估基于Android手机的Ad-hoc多媒体通信在实际应用中的效果,基于Android OS 2.3.6开发了一套Ad-hoc自组织网络通信软件,能够实现无基站环境下手机之间通过多跳传输文本、图片以及语音数据。给出了软件整体功能用例图和关键通信模块的类图和流程图,对单跳和多跳传输时消息的正确接收率和耗电量进行了测试。结果表明,等数据量的不同类型消息在同等距离内的正确接收率差别不明显,文字的正确接收率最稳定,数据量较小时消息的多跳传输正确接收率比数据量大时高。发送端和接收端工作2小时11分耗电量分别占电池总电量的29%和24%。
[Abstract]:In order to evaluate the effect of Ad-hoc multimedia communication based on Android mobile phone in practical application, a set of Ad-hoc ad hoc network communication software is developed based on Android OS 2.3.6. Can realize the transmission of text, pictures and voice data between mobile phones through multiple hops under the environment of no base station. The overall functional use case diagram of the software and the class diagram and flow chart of the key communication modules are given, and the correct reception rate and power consumption of the message in single-hop and multi-hop transmission are tested. The results show that the correct reception rate of different types of messages with the same amount of data is not obvious within the same distance, and the correct reception rate of text is the most stable, and the correct reception rate of multi-hop transmission of data is higher than that of large amount of data. The sender and receiver work for 2 hours and 11 minutes, accounting for 29% and 24% of the total battery power, respectively.
