A Routing Method for Wireless Sensor Networks Based on Digital Watermarking and Energy Balance

Abstract

The invention discloses a wireless sensor network routing method based on digital watermarking and energy equalization and mainly solves problems that network node energy equalization is not fully considered and safe data transmission cannot be effectively realized in the prior art. The method comprises steps that firstly, watermarking is generated and is then embedded into a to-be-transmitted data packet, secondly, based on comprehensively considering distance, safety and residual energy, a node quality evaluation degree is introduced to carry out optimization selection of a next node, thirdly, whether the data packet is tampered in a transmission process can be determined through detection on the watermarking of the received data packet, a node safety degree is adaptively adjusted, and lastly, safe and effective transmission of data of the wireless sensor network is realized. The method is advantaged in that service life of the wireless sensor network is improved, optimization selection of the next node is better realized, node energy equalization and safe data authentication are realized, integral performance is better than methods in the prior art, and the method can be applied to routing selection of the wireless sensor network.

Description

technical field [0001] The invention belongs to the technical field of wireless sensor network security, in particular to a wireless sensor network routing method based on digital watermarking and energy balance. Background technique [0002] The wireless sensor network is composed of a large number of micro sensor nodes deployed in the monitoring area, and its purpose is to cooperatively perceive, collect, process and transmit the monitoring information in the network coverage area. Wireless sensor networks are widely used in environmental monitoring, medical care, military and disaster relief. Since sensor nodes are generally powered by batteries, the balance of energy consumption of nodes becomes the main factor affecting the life of the network. At the same time, due to the deliberate destruction of cyber attackers, the accuracy and security of data transmission in wireless sensor networks is of paramount importance. Therefore, how to balance the energy consumption of ...
