IEEE 1609.3-2007 pdf free.IEEE Trial-Use Standard for Wireless Access in Vehicular Environments (WAVE) – Networking Services.
The scope of this standard is to define services, operating at the network and transport layers, in support of wireless connectivity among vehicle-based devices, and between fixed roadside devices and vehicle-based devices using the 5.9 GFIz DSRC/WAVE mode.
1.2 Purpose
WAVE networking services represents layers 3 and 4 of the OSI communications stack, The purpose of this standard is to provide addressing and routing services within a WAVE system, enabling multiple stacks of upper layers above WAVE networking services and multiple lower layers beneath WAVE networking services. Upper layer support includes in-vehicle applications otTering safety and convenience to their users.
1.3 Document organization
The document contains both normative and informative text. Clause I provides an overview of the document. Clause 2 and Clause 3 contain references, definitions, and abbreviations, respectively. Clause 4 provides extensive explanatory information about the architecture and behavior of the overall WAVE system. including aspects beyond WAVE networking services. Clause 5 specifies the data plane elements of WAVE networking scrvices. which carry uscr data through the system. Clause 6 specifics the managemern plane functions that support system operations. Clause 7 defines the primitives used w communicate between WAVE networking services and other system entities. Annex A and Annex [3 contain a description. and formal definition, of the management infonnation employed by WAVE networking services. Annex C provides an informative bibliography and definitions. Annex D provides a protocol implementation conformance statcmcn (PIUS) proforma.
1.4 Document conventions
Unless otherwise noted, conventions follow those in IEEE Std X02.ll, including conventions for the ordering of information within data items as defined in Clause 7.
Numbers are decimal unless otherwise noted, except IP addresses, which are hexadecimal per the conventions defined in RFC’ 2373. Numbers preceded by Ox indicate hexadecimal numbers, so that OxFF is equivalent to IF hexadecimal.”
Words in italics refer to data items that are defined as either a field in an interface primitive or as an internal data item.
Descriptive, iri1ormaiic information is generally found at the beginning of’ a clause or subclausc. with normative text following Figures are used for illustration and are informative, unless otherwise noted.
1.5 System overview
The system described herein supports high-rate, low latency communications between WAVE devices. Generic lPv6 traffic is supported (not lPv4). as well as a specialized short message service. A control channel provides a common channel for signaling. IP application data is restricted to service channels; short message application data may be sent on either type of channel. Applications benefiting from the WAVE communications can reside on the WAVE devices, or reside on generic devices located on other networks connected to these devices. A more complete description of a WAVE system is provided in Clause 4.
1.6 Applicability
This protocol SUppOrtS wireless communications between any and all VAVE devices. These devices may be mobile. portable, or stationary. The mobile devices include vehicles operating at the high speeds occurring on open highways. A common characteristic of WAVE systems is the need for extremely low communications latency (measured in milliseconds) from initially encountering a device that provides services to completing a set of data transfers.
This standard is consistent with the vehicle-to-roadside and vehicle-to-vehicle communications needs of’ various ITS Architectures. Its intent is to ensure interoperability and robust safely/public safety communications among these WAVE devices.IEEE 1609.3 pdf free download.
