Analysis And Simulation Of The Mobile IP In Satellite Networks

Internet as a data network has seen explosive growth during recent years. Due to the growing importance of the Internet, a new network, such as satellites network, should be designed to facilitate its integration with the Internet. This dissertation is interested in applying mobile Internet Protocol technologies in satellite networks. Recently, the use of Mobile IP has gained attention. The dissertation starting point is the well-known Mobile IP protocol in satellite networks. First, the dissertation introduces the development of Mobile IP in the satellite networks. The detail analysis is given from Mobile IP to Mobile IPv6. The disadvantage of satellite Mobile IP is discussed then. In order to conquer the shortcoming, improved techniques are offered. These methods pay more attention to the mobility of the mobile mode. According to different mobility, the arithmetic reacts different managements. This is called micro-mobility management. It includes DFA,DFA with muti-broadcast, RA, Cellular IP and HAWAII. The management information load is significantly reduced in using these protocols. Registration, routing, QoS, and paging is also discussed here.In thisdissertation, an analysis on mobility approaches suitable for satellite networks handover management is also presented. Although the protocol supports mobility of mobile nodes in the Internet, it performs poorly when handovers happen while a communication session is active in satellite networks. Mobile IP extensions, such as Fast Mobile IP (FMIP), Hierarchical Mobile IP (HMIP), and Fast Hierarchical Mobile IP (FHMIP) which are rarely used in satellite networks have been proposed to handle the drawbacks of Mobile IP in satellite networks in this dissertation. How to make these protocols suitable for satellite networks handover is discussed here. A satellite network structure available for using these protocols is given, under which the simulations is contributed. The different schemes are compared for the same definitions of structure, bandwidth and time delay. At last, a conclusion that FHMIP is more suitable for satellite networks communications is drawn.
