1. A method of communicating between vehicles comprising:
- initiating an internet protocol layer on a first wireless hub of a first vehicle;
synchronizing the first wireless hub with at least a second wireless hub of a second vehicle;
updating network configuration information at the first wireless hub, wherein the network configuration information includes the relative physical positions of the first wireless hub and the second wireless hub;
sending the network configuration information from the first wireless hub to the second wireless hub;
using a routing protocol to discover new routes between the first wireless hub and the second wireless hub, wherein the first wireless hub and the second wireless hub are nodes in an ad-hoc network;
when a route between the first wireless hub and the second wireless hub is not currently available from the routing protocol, temporarily sending packets from the first wireless hub toward the second wireless hub based on the relative physical positions of the first wireless hub and the second wireless hub until any routing protocol finds a new route between the first wireless hub and the second wireless hubreceiving a voice signal at the first wireless hub;
converting the voice signal into packets; and
sending the packets from the first wireless hub to the second wireless hub using a networking protocol.

Abstract
A method of communicating among vehicles in a convoy or otherwise in close proximity is provided. The method includes initiating an internet protocol layer on a wireless hub of a first vehicle. The first vehicle also synchronizes with at least a one other vehicle having a wireless hub. A voice signal is received at the first vehicle. The voice signal is then converted into packets. Finally, the packets are sent from the wireless hub of the first vehicle to the wireless hub of the at least one other vehicle using a networking protocol.

14. A device comprising:
-
a first wireless hub attached to a vehicle and configured to run an IEEE 802.11 standard internet protocol layer, the first wireless hub having a unique identification address; an interface operable to receive a voice signal; and an antenna connected to the first wireless hub, wherein the first wireless hub determines network configuration information, the network configuration information including the relative physical position of the first wireless hub and a second wireless hub in an ad-hoc network including the first wireless hub and the second wireless hub, wherein a routing protocol is used to discover new routes between the first wireless hub and the second wireless hub in the ad-hoc network, and wherein when a route between the first wireless hub and the second wireless hub is not currently available from the routing protocol, packets are temporarily sent from the first wireless hub toward the second wireless hub based on the relative physical positions of the first wireless hub and the second wireless hub until any routing protocol finds a new route between the first wireless hub and the second wireless hub. - View Dependent Claims (15, 16, 17)

18. A method of communicating between vehicles comprising:
-
running an internet protocol layer on a plurality of vehicles; forming an ad-hoc network with the plurality of vehicles; determining the absolute physical position of the plurality of vehicles in the ad-hoc network using at least one of satellite positioning and user input; determining the relative physical position of the plurality of vehicles in the ad-hoc network based on the vehicles absolute physical positions; using a routing protocol to discover new routes between the plurality of vehicles in the ad-hoc network; when a route between a first vehicle and a second vehicle of the plurality of vehicles is not currently available from the routing protocol, temporarily sending packets from the first vehicle to the second vehicle based on the relative physical positions of at least the first vehicle and the second vehicle of the plurality of vehicles in the ad-hoc network until any routing protocol finds a new route between the first vehicle and the second vehicle; recording a voice signal at the first vehicle of the plurality of vehicles; converting the voice signal into packets; and hopping the packets using an IEEE 802.11 standard through the ad-hoc network wherein the packets are sent using an antenna. - View Dependent Claims (19, 20, 21, 22, 23)
