基于异构分簇机制的IPv6 WSN系统设计与实现

摘要

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. 11g 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 good applicability and expansibility.%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IPv6WSN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。
