The invention discloses a method for identifying a distribution class MAC protocol and a hybrid class MAC protocol, which comprises the following steps: S1, building a network model, and obtaining a simulation signal in a network; S2, performing BPSK modulation on the simulation signal, sampling and adding noise; S3, determining start and stop positions of all signal frames in the noise-added sampling signal, and calculating the frame length; S4, dividing the signal frame into a control frame and a data frame; S5, obtaining the frame type and the frame distribution of each protocol; S6, training the support vector machine by taking the frame type and the frame distribution of each protocol as training data to obtain an MAC protocol identification model; And S7, identifying the to-be-identified protocol through the MAC protocol identification model to complete identification of the distribution class and the hybrid class MAC protocol. The method has a very good recognition effect, is relatively suitable for being applied to an actual scene, and solves the problems that the energy characteristics are greatly influenced by noise and the time characteristics are difficult to accuratelyextract.
Description
technical field [0001] The invention relates to the communication field, in particular to a method for identifying allocation-type and mixed-type MAC protocols. Background technique [0002] Existing MAC protocol identification methods usually use energy features or time features as feature parameters. This method can only identify different types or large differences of MAC protocols, and energy features are easily affected by noise. The extraction time The accuracy of time is also very high when characterization, so it will be more limited in the process of practical application. Contents of the invention [0003] In view of the above-mentioned shortcomings in the prior art, a method for identifying allocation-type and mixed-type MAC protocols provided by the present invention solves the problems that energy features are greatly affected by noise and time features are difficult to accurately extract. [0004] In order to achieve the above-mentioned purpose of the invent...
