Abstract:
A dynamic geo-spacial routing methodology for data communication with a wireless communications device comprising the steps of:receiving GPS satellite transmissions in the wireless communications device;acquiring current location data responsive to the GPS satellite transmissions: the current location data including at least latitude and longitude of the wireless communications device;generating an unresolved dynamic IP (UDIP) address as a function of the current location data;transmitting the UDIP address to a remote server for use in routing data communication with the wireless communications device so that the current location of the device determines a dynamic yet unique identifier for data communication;identifying a first gateway on the Internet having a unique name and a predetermined assigned IP address;assigning the selected gateway for temporary use as a dynamic virtual gateway;presenting the designated DVG to the wireless communication device as a virtual host;identifying a second gateway on the Internet having a unique name and a predetermined assigned IP address;assigning the second gateway as a next gateway; andresolving the UDIP to form a resolved dynamic IP address for data communications between the wireless device and a selected one of the first and second gateways.
