Abstract:
1. A wireless terminal comprising: a receiving means for receiving a geocast packet transmitted from a sending terminal; a counting means for determining whether the received geocast packet was previously received at least a number of times; a terminal proximity means for determining the proximity of the wireless terminal to the sending terminal; a geocast-region proximity means for determining the proximity of the wireless terminal to a geocast region; and a retransmission means for selectively retransmitting the received geocast packet on a MANET, the means for selectively retransmitting configured to retransmit the geocast packet based on the determination of the counting means, retransmit the geocast packet based on the determination of the terminal proximity means, if the packet has not been retransmitted based on the determination of the counting means, and retransmit the geocast packet based on the determination of the geocast-region proximity means, if the packet has not been retransmitted based on the determination of the terminal proximity means.
