Abstract: This paper improved the AODV routing protocol and get an energy effective routing and sleeping algorithm for farmland wireless sensor network. This algorithm establishes routing depends on residual energy of each nodes and data collection interval of the destination node. After the data routing is established, the nodes sleeping cycle is determined depends on the data collection cycle of the nodes in the routing. The simulation results shows that by path selection and timely sleeping, this algorithm reduces overall energy consumption and avoids excessive local node energy consumption, So as to achieve the goal to extend the network lifetime.
