The Research On Dyamic Routing Algorithm And Security Mechaism For Satellite Netowrk Basd On Moble Agent

Nowadays, communication network technology has developed rapidly, and satellite networkhas the important strategic significance and has gradually become the world's space powers'research focus. Due to smalle delay, low packet lost rate and the high utilization of spatialfrequency spectrum, LEO satellite plays an important role in satellite networking and hasbecome an essential component of NGI.Satellite routing technology is very critical to improve the timeliness and reliability of thesatellite communication. However, the special factors such as the dynamic topology of LEOsatellite network, limited onboard processing resources and storage resources, space backgroundnoise and uneven global distribution of network traffic make satellite routing technology facingspecial challenges. Because of the characteristics of LEO satellite network terrestrial networkrouting mechanism can not be directly applied to satellite network.And new satellite networkrouting technology must be studied and designed to meet the features of the LEO satellitenetwork.As one of the key components of the satellite network, sufficient attention must be taken tothe security of the routing technology. The security mechanism for the routing technology of thesatellite network is not only the foundation to ensure the routing technology be operated in highefficient and safe way, but also the key point to ensure the safe operation of the satellite network.Therefore, it is very necessary to undertake the research on the security mechanism of thesatellite network routing technology.In this article, the satellite network technology and routing technology is analysised in depthat first, and a new dynamic routing algorithm based on mobile agent suitable for the structure ofthe satellite network changed in high-speed. Based on the research of the existing networkrouting security mechanism, a security protection mechanism for the new dynamic routingalgorithm is proposed. Finally, a simulation platform is built to test and verify the performance ofthe routing algorithm and the security mechanism.
