Abstract

The present invention provides systems and methods for providing mobile users with requested resources. In one such method, first and second location indicators for the mobile user are received, with each of the location indicators having a time associated therewith. The method includes calculating a mobile vector of the mobile user using the first and second location indicators, and associating the mobile vector with a first network region and a second network region. A first portion of the requested resource is sent to a first storage device in the first network region, and a second portion of the requested resource is sent to a second storage device in the second network region. The first and second resource portions are sent to the user when the user is in the first and second network regions, respectively.

17. The method as in claim 1 wherein the first storage device comprises a mobile storage device disposed with a second mobile user.

18. The method as in claim 1, wherein receiving at least one acknowledgement from the mobile user comprises re-sending the first portion of the requested resource to a subsequent storage device in a subsequent network region that is subsequent to the first network region if the at least one acknowledgement is not received when the mobile user is in the first network region.
