22、 The basic communication scenarios are classified in the following way: Scenarios according to the type of communication endpoints: A. Vehicle-to-Vehicle (V2V) communication: communication from an ITS vehicle station to other ITS vehicle stations; B. Roadside-to-Vehicle (R2V) communication: communic
23、ation from an ITS roadside station to ITS vehicle stations; C. Vehicle-to-Roadside (V2R) communication: communication from an ITS vehicle station to ITS roadside stations. NOTE 1: The ITS roadside station is not necessarily connected with other networks, such as the Internet. NOTE 2: R2R communicati
24、on is out of scope of GeoNetworking, however it is basically enabled. In complex scenarios, the concatenation of basic scenarios is possible, for example, V2R + R2V. Communication between different communication endpoints may be realised by the following types of connection: 1. point-to-point: commu
25、nication from an ITS station to another; 2. point-to-multipoint: communication from an ITS station to multiple ITS stations; 3. GeoAnycast: communication from an ITS station to an arbitrary ITS station within a geographical target area; 4. GeoBroadcast: communication from an ITS station to all ITS s
26、tations within a geographical target area. Point-to-point and point-to-multipoint communication are legacy communication scenarios. GeoAnycast and GeoBroadcast are special scenarios in GeoNetworking. Scenarios according to the way how to access the ITS network and transport layer: - direct mode: app
27、lications access directly the ITS network and transport layer, e.g. safety and traffic efficiency applications; - indirect mode: applications indirectly access the ITS network and transport layer, i.e. applications access the ITS network and transport layer via an intermediate layer such as IPv6. NO
28、TE 3: Number of hops, e.g. single hop or multi-hop is not distinguished in the scenarios. Communication is assumed to be n-hop communication, and single-hop communication may be considered as one-hop communication, thus, a special case of multi-hop communication. NOTE 4: Performance requirements, e.
29、g. latency and reliability etc. are also not considered in the classification.
