摘要
为了改善现有移动蜂窝网络在人口密集区域时常出现拥塞的现象,对Ad-hoc和蜂窝网络融合技术进行了研究,提出了一种融合Ad-hoc和蜂窝网络的中继设备实现方案。该方案采用S3C2440控制芯片、无线通信模块和GPRS通讯模块作为硬件开发平台,分析了硬件接口设计和配置,设计了软件系统,实现了Ad-hoc和GSM网络的互联。提出了一种改进的基于信号强度的切换算法,实现了异构网络无缝切换。通过搭建平台对设备进行了测试,结果表明了该设计的可行性。
To improve the congestion phenomenon of existing mobile cellular network in densely populated areas, the Ad-hoc and cellular network integration technology is researehed, and a realization program of relay device which integrates Ad-hoc and cellular network is proposed. The S3C2440 chip, the wireless communication module and GPRS communication module are chose to build the hardware platform; the interface design and configurations are analyzed and the software system are de- signed, then interworking between Ad-hoc with cellular network is realized. Furthermore, an improved switching algorithm is proposed to realize seamless switching in the heterogeneous network. Finally, the design feasibility is verified by testing the de- vice on a constructing platform.
