面向动态外地代理的卫星网络移动性管理机制
Research on mobility management strategy based on the mobile foreign agent domainin satellite networks
摘要
Abstract
Aiming at the high dynamic characteristics ofthe Low Earth Orbit(LEO) satellite networks,a mobility management strategy based on the Mobile Foreign Agent Domainin satellite networks is proposed. The coveragezones of the LEO satellites belonging tothe same location area form a Mobile Foreign Agent Domain,which supports periodic exchange of the intra-domain information between the satellites.The userbelonging to one Mobile Foreign Agent Domain would selectits Mobile Foreign Agentof Trusteeship (MFAT) according to the longest line-of-sight criterion,and select its Mobile Foreign Agent of Attachment (MFAA) according tothe longest dwelling time criterion.Whenthe user's MFAA is changed,the binding update procedures would be triggered between the user and its corresponding Home Agent.With this strategy,the mobility management protocol flow of the LEO satellite networks can be optimized,and the mobility management overhead can be greatly reduced.In a set scenario,the mobility management overhead is 80％ of the mobile IPv6 protocol,and the binding update frequency is reduced by 40％.关键词
