Sensor nodes deployment based on regular patterns in farmland environmental monitoring

To realize feasible wireless sensor nodes deployment in farmland environmental monitoring, the sampling range rs and the communication range rc were proposed for deployment decision based on application requirements. Systematic random deployment and systematic regular deployment in patterns such as triangular lattice, square lattice and hexagon lattice were described in the paper, and the maximum lattice side in each pattern was also given. In addition, deployment cost and connectivity in these three regular patterns were discussed. The method can provide a reference for decision of sensor nodes deployment in farmland environmental monitoring.
