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.

Includes Standards

Level	DocNum	FullName	Description
Mgmt	Addressed Elsewhere	Addressed Elsewhere in Stack	The services related to this portion of the stack are defined in the other standards listed for this solution.
ITS Application Entity	SAE J2735	Dedicated 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 Entity	SAE J2945/1	On–Board System Requirements for V2V Safety Communications	This 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 Entity	SAE J2945/3	Requirements for V2I Weather Applications	This 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.
Facilities	SAE J2945	Dedicated Short Range Communication (DSRC) Systems Engineering Process Guidance for J2945/x Documents and Common Design Concepts	This standard defines cross–cutting material which applies to the J2945/x series including generic DSRC interface requirements and guidance on Systems Engineering (SE) content.
TransNet	IEEE 1609.3	IEEE Standard for Wireless Access in Vehicular Environments (WAVE) – Networking Services	This 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.

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.
