Embodiment Construction

[0060] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0061] figure 1 is a schematic structural diagram of a routing request RREQ message according to an embodiment of the present invention.

[0062] The main difference between the structure of this RREQ message and the structure of the message in AODV is that the "total power to the source node" field is added. This field can be used for the optimal selection of multiple routing paths by the destination node. Reply to the RREQ message with the least power, so as to save the energy consumption of the whole network to the greatest extent.

[0063] figure 2 is a schematic diagram of a routing table structure according to an embodiment of the present invention.

[0064] The routing table is mainly used to query the next-hop address before sending a message, and at the same time query the minimum transmit power required to send a message. The ma...

Abstract

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

technical field [0001] 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 [0002] In recent years, Wireless Sensor Networks (WSN) has attracted worldwide attention. It integrates sensor technology, embedded computing technology, modern network and wireless communication technology, and distributed information processing technology. It is a multidisciplinary Highly cross-cutting, 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 processed by multiple nodes, routed to the coordinator after multiple hops, and finally reach ...
