A vehicle security system for cooperating with a communications network includes a plurality of communication nodes in which a given communication node may transmit an acknowledgment message to an adjacent wireless transceiver upon receipt of a message therefrom. The vehicle security system may include a wireless transceiver and a security controller at the vehicle. The security controller may transmit a message related to vehicle security via the wireless transceiver. The security controller may retransmit the message related to vehicle security if the wireless transceiver does not receive an acknowledgment message from an adjacent communication node. The security controller may not retransmit the message related to vehicle security if the wireless transceiver does receive an acknowledgment message from the adjacent communication node.

That which is claimed is: 1. A vehicle security system for cooperating with a communications network comprising a plurality of communication nodes, a given communication node transmitting an autonomously generated acknowledgment message to an adjacent wireless transceiver upon receipt of a message

That which is claimed is: 1. A vehicle security system for cooperating with a communications network comprising a plurality of communication nodes, a given communication node transmitting an autonomously generated acknowledgment message to an adjacent wireless transceiver upon receipt of a message therefrom, the vehicle security system comprising: a wireless transceiver at the vehicle; and a security controller at the vehicle for transmitting a message related to vehicle security via said wireless transceiver, retransmitting the message related to vehicle security if said wireless transceiver does not receive an autonomously generated acknowledgment message from an adjacent communication node, and not retransmitting the message related to vehicle security if said wireless transceiver does receive an autonomously generated acknowledgment message from the adjacent communication node. 2. The vehicle security system according to claim 1 wherein the communication network comprises a cellular communication network with each communication node comprising a cellular base station; and wherein said wireless transceiver comprises a cellular transceiver. 3. The vehicle security system according to claim 1 further comprising a monitoring station for receiving, via the communications network, the message related to vehicle security from said security controller. 4. The vehicle security system according to claim 1 further comprising a position-determining device at the vehicle for determining a geographic position thereof. 5. The vehicle security system according to claim 4 wherein said position-determining device comprises a Global Positioning System (GPS) receiver. 6. The vehicle security system according to claim 1 further comprising at least one vehicle security sensor connected to said security controller. 7. The vehicle security system according to claim 1 wherein said security controller comprises a data bus interface for interfacing to a data communications bus extending throughout the vehicle. 8. A vehicle security system for cooperating with a cellular communications network comprising a plurality of cellular base stations, each cellular base station transmitting an autonomously generated acknowledgment message to an adjacent cellular transceiver upon receipt of a message therefrom, the vehicle security system comprising: a cellular transceiver at the vehicle; a security controller at the vehicle for transmitting a message related to vehicle security via said cellular transceiver, retransmitting the message related to vehicle security if said cellular transceiver does not receive an autonomously generated acknowledgment message from an adjacent cellular base station, and not retransmitting the message related to vehicle security if said cellular transceiver does receive an autonomously generated acknowledgment message from the adjacent cellular base station; and at least one vehicle security sensor connected to said security controller. 9. The vehicle security system according to claim 8 further comprising a monitoring station for receiving, via the communications network, the message related to vehicle security from said security controller. 10. The vehicle security system according to claim 8 further comprising a position-determining device at the vehicle for determining a geographic position thereof. 11. The vehicle security system according to claim 10 wherein said position-determining device comprises a Global Positioning System (GPS) receiver. 12. The vehicle security system according to claim 8 wherein said security controller comprises a data bus interface for interfacing to a data communications bus extending throughout the vehicle. 13. A method for using a vehicle security system cooperating with a communications network comprising a plurality of communication nodes, a given communication node transmitting an autonomously generated acknowledgment message to an adjacent wireless transceiver upon receipt of a message therefrom, and the vehicle security system comprising a wireless transceiver and a security controller at the vehicle, the method comprising: using the security controller to transmit a message related to vehicle security via the wireless transceiver; using the security controller to retransmit the message related to vehicle security if the wireless transceiver does not receive an autonomously generated acknowledgment message from an adjacent communication node; and using the security controller to not retransmit the message related to vehicle security if the wireless transceiver does receive an autonomously generated acknowledgment message from the adjacent communication node. 14. The method according to claim 13 wherein the communication network comprises a cellular communication network with each communication node comprising a cellular base station; and wherein the wireless transceiver comprises a cellular transceiver. 15. The method according to claim 13 further comprising providing a monitoring station for receiving, via the communications network, the message related to vehicle security from the security controller. 16. The method according to claim 13 further comprising providing a position-determining device at the vehicle for determining a geographic position thereof. 17. The method according to claim 16 wherein the position-determining device comprises a Global Positioning System (GPS) receiver. 18. The method according to claim 13 further comprising providing at least one vehicle security function. 19. The method according to claim 13 wherein the security controller comprises a data bus interface for interfacing to a data communications bus extending throughout the vehicle.
