A topology awareness method, device and system for non-cooperative wireless networks

Abstract

The invention discloses a non-cooperative wireless network-oriented topology sensing method, device, and system. The method includes: obtaining the serial number and sending time of nodes sending data in a target network within a certain period of time through a signal detection mechanism, and forming a data matrix; Carry out Granger causality hypothesis test in pairs, use the time window method to find the mean value of Granger causality zero distribution, and use it as a threshold to screen the potential neighbor set of nodes; perform conditional Granger causality according to the data matrix and potential neighbor set grouping Hypothesis testing, using the time window method to find the mean value of the conditional Granger causal null distribution, and use it as a threshold to filter the final neighbor set of nodes to achieve topology awareness. Through the topology perception algorithm based on conditional Granger causality of the present invention, the Unicom relationship can be inferred according to the signal transmission data matrix without decoding the data packet, the network topology information can be accurately inferred, and the topology inference can be performed using the perception information.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a non-cooperative wireless network-oriented topology sensing method, device and system. Background technique [0002] Topology awareness refers to the perception of the target network's spectrum data, communication timing and other information to infer the topology of the network to guide subsequent battlefield decisions. Network topology information is an extremely important high-level semantic reasoning of the network. Accurately identifying the enemy's network topology on the battlefield can understand the overall situation of the enemy's network, which is conducive to the implementation of strategic decisions; at the same time, it can be further identified on the basis of network topology. The key nodes and links of the network can be precisely interfered with, or assist battlefield resource management decisions. [0003] However, there are still great chal...

Problems solved by technology

This is because non-cooperating parties lead to limited and unreliable information available to the sensing party, and the inability to control the target network data flow also means that related methods based on network protocols cannot work
