A WSN Routing and Sleeping Algorithm in Agriculture Intermittent Data Collection

Farmland environment is away from power facilities and its information collection lasts long time. These characteristics make the wireless sensor networks in agriculture face the problem of energy constraint. Efficient routing and sleeping algorithm can save energy. Considering the node residual energy and the collection cycle of the destination nodes, this paper improved a WSN routing and sleeping algorithm based on the AODV routing algorithm. This algorithm establishes routing path based on the node residual energy and the node collection cycle. Node sleeping cycle determined after the routing path has been established. By routing path selection and appropriate sleeping cycle this algorithm can reduce overall energy consumption and avoid excessive energy consumption of some individual nodes.
