【摘要】：針對(duì)衛(wèi)星網(wǎng)絡(luò)拓?fù)浣Y(jié)構(gòu)的時(shí)變特征,通過(guò)構(gòu)建時(shí)變拓?fù)鋱D序列模型,將衛(wèi)星時(shí)變拓?fù)渚W(wǎng)絡(luò)分解為一系列具有穩(wěn)定狀態(tài)的拓?fù)鋱D結(jié)構(gòu)。綜合考慮節(jié)點(diǎn)在網(wǎng)絡(luò)中的全局性影響和局部性影響,以節(jié)點(diǎn)介數(shù)、節(jié)點(diǎn)緊密度和節(jié)點(diǎn)距離的重要度貢獻(xiàn)為度量參數(shù),提出了穩(wěn)態(tài)衛(wèi)星網(wǎng)絡(luò)節(jié)點(diǎn)重要度評(píng)估方法,設(shè)計(jì)了衛(wèi)星時(shí)變網(wǎng)絡(luò)節(jié)點(diǎn)重要度評(píng)估算法,通過(guò)典型實(shí)例驗(yàn)證了算法的準(zhǔn)確性和有效性。實(shí)驗(yàn)結(jié)果表明,該方法能夠有效地區(qū)分衛(wèi)星時(shí)變網(wǎng)絡(luò)節(jié)點(diǎn)重要度差異,準(zhǔn)確評(píng)價(jià)衛(wèi)星節(jié)點(diǎn)對(duì)衛(wèi)星網(wǎng)絡(luò)資源的控制能力。
[Abstract]:According to the satellite network topology time-varying characteristics by constructing time-varying topology sequence model, the time-varying satellite network topology is decomposed into a series of steady state topology structure. The global effect of influence of the nodes in the network and the local comprehensive consideration of in betweenness, the important contribution of nodes close distance and the node as the metric, presents the steady-state satellite network node importance evaluation method, network node importance evaluation algorithm design of the satellite, through typical examples verify the correctness and validity of the algorithm. The experimental results show that this method can effectively distinguish the time-varying satellite network node important degree difference, accurate evaluation the ability to control satellite nodes on the satellite cyber source.
