Geomessaging Server and Client for Relaying Event Notifications via a VANET
First Claim
1. A method implemented by a geomessaging server for use in a cooperative intelligent transportation system, comprising:
- sending an event notification message, via an infrastructure-based wireless communication network, to a geomessaging client associated with a vehicle that is located within a targeted one of multiple defined geographical areas serviced by the geomessaging server, the message indicating the occurrence of an event pertinent to travel conditions in the targeted area;
generating a message relay request that solicits the geomessaging client to relay the message to any other vehicles within the vehicle'"'"'s vicinity via a vehicular ad-hoc wireless communication network; and
sending the generated request to the geomessaing client via the infrastructure-based wireless communication network.

Abstract
Embodiments include a geomessaging server and a geomessaging client for use in a cooperative intelligent transportation system. The server sends an event notification message, via an infrastructure-based wireless communication network, to a geomessaging client associated with a vehicle that is located within a targeted one of multiple defined geographical areas. This message indicates the occurrence of an event pertinent to travel conditions in the targeted area. The server also generates a message relay request that solicits the geomessaging client to relay the message to any other vehicles within the vehicle'"'"'s vicinity via a vehicular ad-hoc wireless communication network. The sever then sends the generated request to the client via the infrastructure-based network. In at least some embodiments, the geomessaging client relays the message accordingly responsive to receiving the request. This way, the other vehicles will advantageously receive the event notification message even if they are not connected to the server.
