Abstract:
As far as little topology change of Wireless Sensor Networks(WSNs) in application is concerned, network is divided into two grades. The low-grade is composed of multiple clusters, the high-grade consists of cluster heads, it uses routing algorithm of tree between nodes in cluster and cluster heads. A kind of WSNs is constructed by using this algorithm based on STC89C52 MCU, wireless module IP-Link 122x and 1-wire temperature and humidity sensor DS18B20, DHT11. Experiment proves that this design scheme is easy to realize, suitable for building large scale static wireless network.

摘要： 针对无线传感器网络在实际应用中拓扑变化少的特点，将其分为两级，低级别由多个簇组成，高级别由簇首组成，簇首以及簇内节点通信均遵从树状路由算法。采用STC89C52单片机、IP-Link 122x无线模块、DS18B20、DHT11等单总线温湿度传感器构建无线传感器网络。实验证明设计方案实现方法简单，适合于组建大规模的静态无线网络。
