US: SAE Weather Info - WAVE WSMP

Description

This solution is used within the U.S.. It combines standards associated with US: SAE Weather Info with those for V–X: WAVE WSMP. The US: SAE Weather Info standards include upper–layer standards required to implement V2X weather information flows. The V–X: WAVE WSMP standards include lower–layer standards that support connectionless, near constant, ultra–low latency vehicle–to–any communications within ~300m using the WAVE Short Messaging Protocol (WSMP) over IEEE WAVE in the 5.9GHz spectrum. The broadcast mode is interoperable with M5 FNTP.

SecurityIEEE 1609.2IEEE Standard for Wireless Access in Vehicular Environments – Security Services for Applications and Management MessagesThis standard defines secure message formats and processing for use by Wireless Access in Vehicular Environments (WAVE) devices, including methods to secure WAVE management messages and methods to secure application messages. It also describes administrative functions necessary to support the core security functions.
SecurityIEEE 1609.2aIEEE 1609.2a–2017 – IEEE Standard for Wireless Access in Vehicular Environments––Security Services for Applications and Management Messages – Amendment 1This standard defines secure message formats and processing for use by Wireless Access in Vehicular Environments (WAVE) devices, including methods to secure WAVE management messages and methods to secure application messages. It also describes administrative functions necessary to support the core security functions.

It also describes administrative functions necessary to support the core security functions.
ITS Application EntitySAE J2735Dedicated Short Range Communications (DSRC) Message Set Dictionary (TM)This standard defines the data and messages for use in DSRC (i.e., V2V, V2I, and V2D) applications. The SAE J2945 series defines additional requirements on how to use these messages.
ITS Application EntitySAE J2945/1On–Board System Requirements for V2V Safety CommunicationsThis standard specifies the system requirements for an on–board vehicle–to–vehicle (V2V) safety communications system for light vehicles, including standards profiles, functional requirements, and performance requirements.
ITS Application EntitySAE J2945/3Requirements for V2I Weather ApplicationsThis document specifies interface requirements between vehicles and infrastructure for weather applications, including detailed systems engineering documentation (needs and requirements mapped to appropriate message exchanges). The purpose of this SAE Standard is to enable interoperability supporting these weather applications over a communications technology agnostic interface.
FacilitiesSAE J2945Dedicated Short Range Communication (DSRC) Systems Engineering Process Guidance for J2945/x Documents and Common Design ConceptsThis standard defines cross–cutting material which applies to the J2945/x series including generic DSRC interface requirements and guidance on Systems Engineering (SE) content.
TransNetIEEE 1609.3IEEE Standard for Wireless Access in Vehicular Environments (WAVE) – Networking ServicesThis standard defines the network and transport layer options for the WAVE environment. The standard defines three options: a bandwidth efficient single–hop solution known as WSMP, UDP/IP, and TCP/IP. It has been harmonized with ISO FNTP and FSAP – a common message format specified in ISO 16460.
AccessIEEE 1609.4IEEE Draft Standard for Wireless Access in Vehicular Environments – Multi–Channel OperationThis standard primarily defines the data link layer of the WAVE communications stack.
AccessIEEE 802.11IEEE Draft Standard for Information technology––Telecommunications and information exchange between systems Local and metropolitan area networks––Specific requirements Part 11: Wireless LAN Medium Access Control (MAC) and Physical Layer (PHY) SpecificatioThis standard defines the physical and data link layers for wireless Ethernet, including WiFi and DSRC.
AccessISO/IEC 8802–2IEEE Standard for Information technology –– Telecommunications and information exchange between systems––Local and metropolitan area networks –– Specific requirements –– Part 2: Logical Link ControlISO/IEC 8802–2 describes the logical link control (LLC) sublayer, which constitutes the top sublayer in the data link layer of the ISO 8802 Local Area Network Protocol (also known as IEEE 802.2).

Readiness: High–Moderate

Readiness Description

One significant or possibly a couple minor issues. For existing deployments, the chosen solution likely has identified security or management issues not addressed by the communications solution. Deployers should consider additional security measures, such as communications link and physical security as part of these solutions. They should also review the management issues to see if they are relevant to their deployment and would require mitigation. For new deployments, the deployment efforts should consider a path to addressing these issues as a part of their design activities. The solution does not by itself provide a fully secure implementation without additional work.
