Handover management in low Earth orbit satellite IP networks

In the paper, we investigate issues of Internet-based services provisioned via low earth orbit (LEO) satellite-IP networks, which are equipped with on-board IP routers. We propose a possible network-integrating architecture for global personal communication based on IP (Internet protocol) networks. We investigate particularly challenges of handover management in LEO satellite networks, arising due, to the movement of the satellites. Handover management schemes based on mobile IPv6 are proposed for handling inter-satellite handover. Performance evaluations of the proposed schemes are carried out by means of simulation
