Networking method of wireless sensor network and wireless sensor network system

Abstract

The invention relates to a networking method of a wireless sensor network. According to the method, broadcast messages are sent through triggering a concentrator or a cluster head node by a host machine, and in addition, stage-by-stage networking is completed according to answering messages, wherein various factors such as the hop count, the position information, the rest energy and the external environment of the wireless sensor network node are integrally considered, a cluster head node and a blade node are voted through equivalent distances, in addition, a classical binary tree structure is adopted for networking, the cluster head node and the blade node are more scientifically distributed, and the energy utilization rate of the single node is effectively improved, so the node can be ensured to stably work in three years or even a long period, and the breakdown of the whole network caused by too early failure of partial nodes is avoided. The structure of the host machine of a wireless sensor network system is simple, the configuration method is flexible, developers do not need to deep understand the wireless protocol, the network building and application can be completed only through carrying out corresponding network configuration on the wireless sensor network node on the host machine, and the networking is convenient and flexible.
