【摘要】：為滿足空間通信的要求,空間數(shù)據(jù)系統(tǒng)咨詢委員會制定了空間通信協(xié)議規(guī)范.在SCPS-NP協(xié)議的基礎(chǔ)上,利用最短路徑算法,設(shè)計一種點到點QoS單播路由機制.為適應(yīng)衛(wèi)星網(wǎng)絡(luò)動態(tài)變化的特點,采用時隙劃分的方式對空間信息網(wǎng)進行分析,建立了相應(yīng)的節(jié)點模型和拓撲模型.利用本文設(shè)計的路由機制,綜合考慮QoS滿意度和服務(wù)定價滿意度,在空間信息網(wǎng)中找到滿足QoS的路徑.將所設(shè)計的QoS路由機制在NS2平臺進行仿真實現(xiàn)并對路由機制進行了性能評價.實驗結(jié)果表明,設(shè)計的機制是可行和有效的,比基準機制性能更優(yōu).
[Abstract]:In order to meet the requirements of space communication, the Advisory Committee of Spatial data Systems has formulated the specification of space communication protocol. Based on SCPS-NP protocol, a point-to-point QoS unicast routing mechanism is designed by using the shortest path algorithm. In order to adapt to the dynamic change of satellite network, the spatial information network is analyzed by slot division, and the corresponding node model and topological model are established. Using the routing mechanism designed in this paper, the QoS satisfaction and the service pricing satisfaction are considered synthetically, and the path to satisfy QoS is found in the spatial information network. The designed QoS routing mechanism is simulated on NS2 platform and the performance of the routing mechanism is evaluated. The experimental results show that the designed mechanism is feasible and effective, and the performance of the proposed mechanism is better than that of the benchmark mechanism.
