System and method for geocasting in a mobile ad hoc network
First Claim
1. A method for determining whether a wireless terminal will retransmit a received packet, said method comprising:
- determining a first distance from said wireless terminal to a point in a geocast region;
determining a plurality of distances between said point and each of a plurality of wireless terminals from which said wireless terminal has previously received a packet having an identifier that is the same as an identifier of said received packet;
storing said received packet in a transmit queue;
assigning a priority to said received packet, wherein said priority is based on differences between said first distance and each of said plurality of distances; and
retransmitting said received packet if said first distance is less than each of said plurality of distances.

Abstract
Disclosed is a wireless terminal that determines whether to retransmit a received packet. The wireless terminal is configured to determine a first distance from the wireless terminal to a point (e.g., the center point) in a geocast region. The wireless terminal is also configured to determine a plurality of distances between the point and each of a plurality of wireless terminals from which the wireless terminal has previously received a packet having an identifier that is the same as an identifier of the received packet. The wireless terminal is configured to retransmit the received packet if the first distance is less than each of the plurality of distances.
