The invention relates to an energy-saving routing method for wireless sensor network based on power control. The invention relates to establishment of optimum communication power between node and neighbor, establishment of energy-optimizing route. The invention provides a power control method for minimizing communication power between nodes, based on that and designs an energy-saving routing protocol considering multipath total consumption and selecting path of minimum power consumption for data transmission based on AODV routing protocol; the routing protocol can save energy in energy-limited wireless sensor network.
Description
A Power-Control-Based Energy-Saving Routing Method for Wireless Sensor Networks technical field The invention relates to a wireless router network technology, in particular to a high-efficiency and energy-saving routing method for a wireless sensor network based on power control. Background technique In recent years, Wireless Sensor Networks (WirelessSensorNetworks, WSN) has attracted widespread attention worldwide. It integrates sensor technology, embedded computing technology, modern network and wireless communication technology, distributed information processing technology, etc., and is a highly cross-disciplinary , Emerging frontier research fields. WSN is composed of a large number of micro sensor nodes deployed in the monitoring area, and forms a multi-hop self-organizing network system through wireless communication. The data monitored by sensor nodes is transmitted hop by hop along other sensor nodes. During the transmission process, the monitoring data may be pr...
