Abstract

A method is disclosed for initiating real-time geo-game using geocast messaging according to a scalable tiered geocast protocol. The method includes a first wireless terminal (WT), programmed with a geo-gaming application and the scalable tiered geocast protocol, geocasting a game declaration to a destination geocast region containing potential participants. The method also includes a second WT, of one of the potential participants, and programmed with the geo-gaming application and the scalable tiered geocast protocol, receiving the game declaration in the destination geocast region and responding by geocasting a response message indicating interest in participating in the real-time geo-game.

4. The method of claim 3, wherein:

the first WT is a first team proxy device for the first team, sending and receiving game communications on behalf of the first team; and

the second WT is a second team proxy device of the second team, sending and receiving game communications on behalf of the second team.

5. A method for transmitting a virtual game object from a first player to a second player of a real-time geo-game using geocast messaging according to a scalable tiered geocast protocol, the method comprising:

a first processor of a first wireless terminal (WT) receiving a first action input from a first user and, in response to receiving the first action input;

generating a first geocast data packet for sending a virtual game object toward a second WT, the first geocast data packet including;

a first destination geocast region including the second WT; and

first movement information indicating first movement

characteristics of the virtual game object; and

geocasting the first geocast data packet to the first destination geocast region according to transmission heuristics of the scalable tiered geocast protocol.

6. The method of claim 5, further comprising at least one intermediate WT receiving and, according to the transmission heuristics of the tiered geocast protocol, retransmitting the first geocast data packet.

7. The method of claim 5, further comprising the first processor causing a display of the first WT to show a representation of at least one virtual game characteristic selected from a group of virtual game characteristics consisting of:

(i) a portion of a first playing field associated with the first WT;

(ii) a portion of a second playing field associated with the second WT;

(iii) a first player moving with respect to the first playing field, and

(iv) a second player moving with respect to the second playing field.

8. The method of claim 7, wherein the first processor, in causing the display of the first WT to show the representation of at least one virtual game characteristic, shows the characteristics with representation of an actual environment in which the first WT is being operated to create an augmented reality experience for the first user using the first WT.

9. The method of claim 5, further comprising a second processor, of the second WT:

receiving the first geocast data packet; and

determining if a present geographic location of the second WT bears a predetermined relationship to a first impact location provided in the first movement information.

10. The method of claim 9, wherein:

the second WT includes a second memory; and

the method further comprises the second processor, if the second processor determines that the present geographic location of the second WT does not bear the predetermined relationship to the first impact location, performing at least one step of;

(i) recording a score for the first WT in the second memory; and

(ii) the second processor including, in a subsequent data packet, indication of the score for the first WT, and geocasting the subsequent data packet to the first WT according to transmission heuristics of the scalable tiered geocast protocol.

11. The method of claim 10, wherein the second processor, in including, in the subsequent data packet, indication of the score for the first WT, and geocasting the subsequent data packet to the first WT according to transmission heuristics of the tiered geocast protocol, determines whether to transmit on a first tier network or a second tier network, and the method further comprises:

20. The method of claim 18, further comprising:

the first WT determining that a scoring event has occurred based on the first WT not receiving a geocast message from the second WT indicating that the second WT intercepted a virtual object of the geo-game;
