1. A wireless terminal comprising:
- means for determining the geographical location of the wireless terminal;
means for receiving a geocast packet originally transmitted from an originating terminal, the geocast packet including an identification of a geocast region;
means for determining on which one of a plurality of networks to retransmit the geocast packet, or not at all, based on;
a distance between the wireless terminal'"'"'s geographical location and a location of the originating terminal,whether the geocast packet has been transmitted over the long range network, anda distance between the wireless terminal'"'"'s geographical location and the geocast region;
means for transmitting the geocast packet on a MANET; and
means for transmitting the geocast packet on the long range network;
wherein the means for determining on which one of a plurality of networks to retransmit the geocast packet, or not at all, determines not to retransmit said the geocast packet if;
the geocast packet has already been transmitted over the long range network,the wireless terminal is not located within the geocast region, andthe distance between the wireless terminal'"'"'s geographical location and the location of the origination terminal is greater than a threshold.

Abstract
A method and system for geocasting data packets in a MANET. The MANET is combined with a long-range network such that a wireless terminal can decide whether to rebroadcast a geocast packet over the MANET, the long-range network, or not at all, depending on the wireless terminal'"'"'s proximity to the geocast region, the location of the originating wireless terminal, or both. A wireless terminal close to or within the geocast region can rebroadcast on the MANET, whereas a wireless terminal far from the geocast region can rebroadcast on the long-range network.

12. A method for geocasting, the method comprising the steps of:
-
receiving at a wireless terminal a geocast packet originally transmitted from an originating terminal, the geocast packet including an identification of a geocast region; and determining on which of a plurality of networks to retransmit the geocast packet, or not at all, based on; a distance between the wireless terminal and the geocast region, whether the geocast packet has been transmitted over the long range network, and a distance between the wireless terminal and the originating terminal; wherein the determining step determines not to retransmit the geocast packet if; the geocast packet has already been transmitted over the long range network, the wireless terminal is not located within the geocast region, and the distance between the wireless terminal and the originating terminal is greater than a threshold. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A network comprising:
a MANET formed by a plurality of wireless terminals, each wireless terminal being operable to; receive a geocast packet originally transmitted from an originating terminal, the geocast packet including an identification of a geocast region; determine on which one of a plurality of networks to retransmit the geocast packet, or not at all, based on; a distance between the wireless terminal'"'"'s geographical location and a location of the originating terminal, whether the geocast packet has been transmitted over the long range network, and a distance between the wireless terminal'"'"'s geographical location and the geocast region; transmit the geocast packet on a MANET; and transmit the geocast packet on the long range network, wherein the geocast packet is not retransmitted if; the geocast packet has already been transmitted over the long range network, the wireless terminal is not located within the geocast region, and the distance between the wireless terminal'"'"'s geographical location and the location of the origination terminal is greater than a threshold. - View Dependent Claims (24)
