Abstract

Farmland wireless sensor network is characterised by its large deployment area and the unfixed location of sink node. In order to work out a more efficient and less energy-consuming way for the mobile sink node to collect the data of the network, the paper proposed a data collection scheme for mobile terminal based on hierarchical topology—DCSMT_H. Taking the location of nodes and residual energy into account, a clustering topology was built by selecting the cluster heads in the scheme, and finally a inter-cluster data routing was constructed flexibly according to the current location of the mobile terminal. Simulation experiments showed that DCSMT_H possessed low energy-comsumption network and extend the lifetime of the network by about 15% compared with LEACH. So DCSMT_H being appliod to the mobile terminal can well fit for collecting the environmental information of large-scale farmlands. This research can provide references for improving the application of wireless sensor networks in precision agriculture.
