Embodiment Construction

[0057] The present invention will be further described below in conjunction with the accompanying drawings. like figure 1 As shown, a QoS-based satellite network k-terminal reliability analysis algorithm, the specific steps are as follows:

[0058] Step1: According to the satellite network topology, select k target nodes as the research object, and select one of the nodes s i as the initial fusion point. And input the correlation matrix M(G), the QoS requirements of transmission bandwidth-sensitive services, delay-sensitive services and reliability-sensitive services, and the state of the network at this time.

[0059] Step2: Determine the number of non-zero elements in row i. If there is only one non-zero element in row i Referred to as

[0060] Step3: Matrix linear transformation: Add the jth column element in the adjacency matrix M to the ith column, add the jth row element to the ith row, delete the jth row and jth column, update the matrix M, and reduce the order ...

Abstract

The invention discloses a satellite network k-end reliability analysis method based on QoS. The method comprises the following steps of: analyzing a reliability index; analyzing multiple states of the link; and calculating the reliability of the k end of the satellite network based on QoS. According to the method, firstly, non-fusion elements are subjected to zero setting and non-fusion operation, network topology adjacency matrix transformation is carried out, a path communicating k nodes is obtained, the number of matrix transformation times is effectively reduced, and redundant links are avoided; then, the link is divided into a plurality of states, different states correspond to different link bandwidths, services are divided into three types by considering QoS index differences caused by service type differences, and available paths meeting the conditions in the satellite network are determined according to QoS constraint conditions of different services and the current state of the link; finally, the reliability of the k-end path under different services is calculated according to the reliability of the current state of the link; not only is the accuracy of reliability calculation improved, but also the calculation efficiency is improved; and the method has good application prospects.

Description

technical field [0001] The invention relates to a reliability analysis technology for satellite network transmission, in particular to a reliability analysis method for satellite network k-terminal communication which comprehensively considers QoS (Quality of Service, service quality) indicators of various services. Background technique [0002] The satellite network itself is a complex system with complex structure, diverse functions, and changing operating environment, which will lead to more unreliable factors affecting the satellite communication network. On the one hand, because satellite nodes are exposed to the complex environment of space, they are vulnerable to attacks, and satellite failures or failures occur, which affects the reliability of satellite network communications. On the other hand, due to the wide beam range, the satellite communication link may be affected by many uncertain factors such as sudden interference, heavy rainfall, dense fog, and heavy haze...
