Abstract

The invention relates to a non-cooperative topology inference method based on unknown node positions. The non-cooperative topology inference method comprises the following steps: monitoring the power of a non-cooperative network in a given area L by using sensor nodes randomly distributed in the given area L; dividing the given area L into equal grids, and obtaining the power of each grid according to the power detected by the sensor nodes; inputting the power of each grid into a neural network to obtain a coordinate position of a non-cooperative node; monitoring a time sequence of the non-cooperative nodes by using a sensor network; constructing an autoregression model of the non-cooperative nodes and formed node pairs according to the time sequence of the non-cooperative nodes; using the residual sum of squares of the autoregression model to construct statistics; and obtaining the causal relationship of the non-cooperative node sum. According to the non-cooperative topology inference method based on the unknown node position, node positioning and causal inference are combined into one system to realize topology inference when the node position is unknown.

Description

technical field [0001] The invention belongs to the technical field of positioning and topology inference, and relates to a non-cooperative topology inference method based on unknown node positions. Background technique [0002] The Internet has become ubiquitous in today's world. From climate research to cancer research, from computational neuroscience to econometrics, scenarios can be modeled as networks with multiple interacting variables. In the study of these networks, a major goal is to determine how specific variables affect other variables. [0003] In network research, inferring causal relationships between network nodes will help to better understand how different components of the network interact. In wireless network management, topology reasoning can provide administrators with information to help them troubleshoot and enhance the security and robustness of the network. For monitoring wireless networks, especially in the field of electronic warfare, topologic...
