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.
Claims8
A location-based flooding method for a wireless terminal, the method comprising the steps of:
- receiving a geocast packet transmitted from a sending terminal;
- and
- determining whether to retransmit the geocast packet on a MANET based at least on the number of times the geocast packet was previously received;
- and
- if it is determined not to retransmit the geocast packet based on the number of times the geocast packet was received, determining whether to retransmit said geocast packet based on the proximity of the wireless terminal to the sending terminal;
- and
- if it is determined not to retransmit the geocast packet based on the proximity of the wireless terminal to the sending terminal, determining whether to retransmit said geocast packet based on the proximity of the wireless terminal to a geocast region.
