摘　　要：为了满足传感器节点大规模部署的需求,文中设计并实现了基于异构分簇机制的IPv6 WSN系统。系统中,簇内传感器节点基于Contiki操作系统,完成传感数据的采集,并将采集数据通过802.15.4协议以单跳或多跳形式发送到簇首;簇首节点基于Linux操作系统,通过802.11g协议以自组织形式组网,完成传感信息的高速率传输以及传感器采集数据在网关的汇聚。通过网关中的嵌入式Web服务器,可以实现对传感器网络的实时远程监测。实验表明,该系统保证传输链路稳定可靠,满足大量传感器采集数据高速远距离传输要求,具有良好的应用性和可扩展性。In order to meet the needs of large-scale deployment of the sensor nodes, design and implement a system for IPv6 wireless sen- sor network based on clustered heterogeneous mechanism. In this system, the cluster nodes are based on Contiki operating system to col- lect data. The cluster nodes transmit collected data to the cluster head nodes in single hop or multi-hop way with 802.15.4 protocol. The cluster head nodes are based on Linux operating system and build network by self-organization with 802. 11 g protocol to transmit collect- ed data to the gateway at a high speed. With accessing embedded Web server in gateway, users can monitor wireless sensor network re- motely anytime. Experiments show that the system ensures transmission link is stable and reliable. The system meets the needs of transmit- ting a large of collected data long distance in high speed and has ~ood anolicabilitv and exoansibilitv.
