摘　　要：无线传感器网络与互联网结构的差异使得两者在接入与数据包处理等方面都面临着一定的技术难点。针对基于IPv6协议的低速无线个域网6Lo WPAN(IPv6 over Low Power Wireless Personal Area Network)与互联网接入方式的问题,用无线射频接入方式代替串口通信方式,提高通信过程中通信速率。同时结合无线传感器网络技术、嵌入式技术、轻量级网络地址转换/协议转换技术u NAT-PT(Micro Network Address Translation-Protocol Translation)、站间自动隧道寻址协议技术ISATAP(Intra-Site Automatic Tunnel Addressing Protocol)和进程间通信IPC(Inter-Process Communication)机制,在网关处实现了两者之间的自适应适配互通机制,优化数据包流向问题。实验结果表明,无线射频接入方式与协议适配的自适应数据包调度机制能够提高通信过程中的通信速率,减少网络时延,优化网关通信性能。The diversity of structure between Wireless sensor network and Internet leads to numerous technical diffi-culties in access and data interaction. Specific to internet access between 6LoWPAN（ IPv6 over Low power Wireless Personal Area Network） and Internet,a resolution using by radio frequency technology,improved the rate of networ-king,is proposed to instead of serial communication. Combined with Wireless Sensor Network,Embedded technolo-gy,technology of Micro Network Address Transition-Protocol Transition（ uNAT-PT） and Intra-Site Automatic Tunnel Addressing Protocol（ISATAP）,and Inter_Process Communication（IPC）,a adaptive adaptation mechanism is real-ized in gateway to optimized data processing. Experimental results show that access of radio frequency worked to-gether with the scheduling model of adaptive mechanism can effectively improve the rate of communication and re-duce the latency.
