In this paper, an analysis on mobility approaches suitable for satellite networks handover management is presented. The paper starting point is the well-known Mobile IP protocol in satellite networks. 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 paper. 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.
