摘　　要：在实际应用中,IEEE 802.15.4规范是低速率无线个人网络的标准,使用6LoWPAN为其网络协议,要求将内部的IPv6地址转换为外部IPv4地址,从而实现无线传感器网络的设计。为使家庭传感器网络连接到Internet,设计一种基于简化映射协议栈和逻辑地址分配方案的系统架构,其中主要对IPv6和IPv4地址的哈希函数进行匹配。此外,设计一个动态地址协议和端口映射模型来处理由传感器位置移动或电能耗尽所引起的频繁的网络结构变化。在实验中,构建家庭传感器网络网关来说明该模型的可行性。实验结果表明,网关具有较低的延迟时间,可以对传感器的移动做出迅速响应,以更少的信息交换过程重组家庭网络。IEEE 802.15.4 specification is the standard for low⁃rate wireless personal network.When using 6LoWPAN as its network protocol,it is required that the internal IPv6 address should be converted into an external IPv4 address,so as to achieve the design of wireless sensor networks.The system architecture based on simplified mapping protocol stack and logical address allocation scheme is designed to connect the home sensor network to the Internet,from which the hash function of IPv6 and IPv4 addresses are mainly matched.In addition,a dynamic address protocol and port mapping model are designed to deal with the frequent network structure changes caused by the sensor location moving or power depletion.In the experiment,a family sensor network gateway is built to illustrate the feasibility of the model,and the experimental results show that the gateway has lower delay time,can respond quickly to the movement of sensors,and restructure the family network with much less information exchange process.
