Abstract

Trains travel at speeds ranging from 0 to 80m/s (0 to288 Km/hr).Providing in-train wireless Internet access tomultimedia applications will require the use of a mobilenetworking protocol, such as Mobile-IP, to achieveuninterrupted connectivity.Although Mobile-IPrepresents a promising solution, its performance under"extreme" mobility is questionable.We simulated a trainscenario and identified the limitations of the currentmobile-IP standard in terms of throughput, handoff, andpacket loss of a train moving at different velocities.Weinvestigated the performance of UDP- and TCP-sessions,and examined the effect of different base stationinterleaving distances on throughput and packet loss.Theresults presented in this paper are part of an investigativeresearch into adaptive mobile networking protocols inrapidly mobile networks.
