WSN Layer-cluster Sensor Deployment for Frozen Soil Data Acquisition

Abstract

In the large-scale system of frozen soil data acquisition, the problem of sensors deployment is still widely researched. Although various methods of sensors deployment have been proposed, which are based on wireless sensor networks (WSN), sensors deployment utilization and energy utilization need to be improved in WSN. Therefore, a method for large multi-node deployment of hybrid layer-cluster topology in WSN is proposed in this paper. The experimental results in Mohe show that the layer cluster hybrid topology model based on hexagon partition can reach the coverage rate of 100% and the energy utilization rate increasing by 5.4% and 8.6% on the condition of relatively less deployed sensor nodes. The method is an effective solution to the problem of node deployment for frozen soil data acquisition of large-scale and multi-node in WSN.
