摘　　要：Internet用户借助无线传感网络(WSN)有效控制周围的物理世界已成为前沿热点问题.提出基于6LoWPAN技术的WSN接入(IPv4)Internet的方法,融合网络地址-协议转换技术,6LoWPAN网络边缘路由器集成了以太网路由,实现6LoWPAN与(IPv4)Internet之间的数据包转换.测试分析得出,本文方法改善了接收率和网络时延,并使两异构网之间在网络层面上实现了统一,促进网络的无缝融合;使异构网节点在业务层面上达到了直接的端到端交互,拓展业务的延伸.It has been becoming the frontiers and hotspots for Internet users to control surrounding phys- ical world depending on WSN technology. In the paper, method of WSN access （IPv4）Internet was presented based on 6LoWPAN technology; Network Address Translation-Protocol Translation technol- ogy and Ethernet routing were respectively fused and integrated in border router, Realize data packet conversion between 6LoWPAN and （IPv4）Internet. Result in the test shows new method improves re- ception rate and network delay, moreover, allows two heterogeneous network to achieve a unified at net- work level, Facilitates seamless integration of networks; and makes heterogeneous network nodes a- chieve end-to-end direct interaction at the operational level, expands their business extension.
