Abstract:
1. A method of geo-casting a message to a plurality of recipients each having an address and a known geographic location, comprising: reporting the current locations and addresses of the plurality of recipients to a geospatial database; designating an arbitrary geographic region to transmit the message to by reference to a physical structure within the geographic region; determining the addresses of the recipients that are located within the geographic region by using the geospatial database to compare the current reported locations of the recipients with the reference to the structure, the address of at least one of the recipients being an internet protocol (IP) address; changing the wide area network address of the recipient to dynamically obtain a new IP address due to movement of the recipient; and transmitting the message to the addresses of each of the recipients having current locations within the geographic region by serially unicasting the message, over a mobile ad hoc network, operating a computer at an OSI application level.
