Geocast is a network routing scheme that delivers packets to the nodes within a specific geographic area. It is distinguished from unicast, broadcast, multicast, and anycast in that recipients are specified by location rather than by address or group, and it can be regarded as a variant of multicast. It is studied for uses such as sending warnings to vehicles around an accident site in vehicle-to-vehicle communication (VANET) or propagating disaster alerts by region.
