AI Technical Summary

Technical Problem

When wireless sensor networks face interference attacks, especially when there are a large number of low-power nodes in the network, data transmission is easily interrupted or lost. Existing multi-hop routing and redundant transmission methods cannot effectively solve this problem.

Method used

By acquiring the remaining power, location information and communication quality parameters of sensor nodes in real time, a multi-hop routing path is dynamically selected, low-power nodes are excluded, and nodes in high-power and low-interference areas are prioritized to generate at least two independent redundant paths. When the node power is low, a routing reconstruction mechanism is triggered, and information is restored by combining data fusion and verification algorithms.

Benefits of technology

It achieves reliability and stability of transmission in interference environments, avoids interruptions caused by insufficient node power, ensures information integrity through redundant paths and data verification technology, and improves the long-term stable operation capability of the network.

Abstract

The invention relates to the field of communication transmission, and discloses an anti-interference secure transmission method for a wireless sensor network, which comprises the following steps of: acquiring residual electric quantity, position and communication quality parameters of a sensor node in real time; dynamically selecting a multi-hop routing path based on interference detection, excluding low-electric-quantity nodes, and preferentially selecting high-electric-quantity and low-interference area nodes to form a main path; at least one independent redundant path is generated according to the node electric quantity distribution and the interference intensity, and the relay node electric quantity of the redundant path is higher than a threshold value; monitoring electric quantity change in real time, and triggering a route dynamic reconstruction mechanism; and recovering complete information through a data fusion and verification algorithm. In addition, a charging request protocol is triggered for a low-power key node. According to the invention, by optimizing routing selection, redundancy transmission and energy management strategies, the anti-interference capability and transmission reliability of the wireless sensor network are improved, and the problem of data interruption caused by insufficient electric quantity of nodes is avoided.
