Research and implementation of forest fire early warning system based on UWB wireless sensor networks

In this paper, ultra-wideband technology and the wireless sensor networks are introduce for the purpose of forest fire early warning system. The system is the basis of information disposal, sensing and wireless communication technique. The system includes the following aspect: the integration of wireless temperature sensor, the integration of wireless humidity sensor, the corresponding network topology, the network communication protocol, the node energy and the relative experiments. The system has a star structure which adopts the cluster-tree topology. The network platform is low cost, easy to install and convenient to use. The system greatly improves the efficiency of forest fire prevention and reduces the loss of forest.
