dc.description.abstractVehicular ad hoc networks (VANETs) or inter-vehicle
dc.description.abstractcommunication (IVC) makes possible the development of a number of
dc.description.abstractinnovative and powerful transportation system applications. VANET
dc.description.abstracttechnology proves an important extension of both cellular and
dc.description.abstractwireless local area networks (WLANs) currently used in the
dc.description.abstracttransportation industry. It is widely recognized that the
dc.description.abstracttransportation industry serves as an ideal platform for a large
dc.description.abstractnumber of existing and future wireless applications, many of which
dc.description.abstracthave yet to be developed for commercial use.
dc.description.abstractSafety messaging is one of the most critical uses for VANET,
dc.description.abstractsupporting a number of potential safety applications, e.g. emergency
dc.description.abstractelectronic brake lights, lane change and pre-crash warning, among
dc.description.abstractothers. Many applications require extremely low latency (less than
dc.description.abstract100ms) and highly reliable (over 99\% packet delivery ratio)
dc.description.abstractcommunication services. In order to satisfy these critical
dc.description.abstractrequirements, an efficient media access control (MAC) layer is
dc.description.abstractnecessary. At the time of this writing, a de facto standard of VANET
dc.description.abstractMAC is being developed.
dc.description.abstractExtensive VANET MAC research with regard to safety applications has
dc.description.abstractyet to be done. The proposed base for the VANET future standard uses
dc.description.abstractan 802.11a media access layer whose performance-although studied-is
dc.description.abstractknown to contain deficiencies and was accomplished outside the
dc.description.abstractVANET context. These factors motivated the author to initiate the
dc.description.abstractstudy of VANET and MAC.
dc.description.abstractIn this work, MAC for VANET MAC is extensively researched, and a
dc.description.abstracthistory of MAC is initially reviewed. The special and critical
dc.description.abstractrequirements of VANET MAC are presented and four major categories
dc.description.abstractwere investigated and analyzed. Because the under-development of
dc.description.abstract802.11p is based on the IEEE 802.11a, special consideration is given
dc.description.abstractwith regard to the performance of 802.11a MAC and associated
dc.description.abstractrequirements. Extensive research enhancements centering on safety
dc.description.abstractapplications of the 802.11 MAC are conducted. The author's research
dc.description.abstractgenerated a platform in which VANET performance can be
dc.description.abstractquantitatively evaluated, analyzed, and verified. The quantitative
dc.description.abstractbehavior of the current protocols/algorithms, which include delay
dc.description.abstractand packet delivery ratio, are presented on this platform.
dc.description.abstractFurthermore, the future protocol and algorithm proposals can be
dc.description.abstractadded into this platform so that a faster research cycle can be
dc.description.abstractachieved. Through theoretical analysis and simulation, this
dc.description.abstractinvestigation shows that current proposed VANET MAC and 802.11a MAC
dc.description.abstractenhancements have yet met the critical requirements of VANET. The
dc.description.abstractfuture work may focus on how to use this theoretical model and
dc.description.abstractsimulation tool to assist MAC layer protocol design. Meanwhile, when
dc.description.abstractnew algorithms are proposed or accepted by the standard, this model
dc.description.abstractand tool can serve as a fast and convenient platform, where the new
dc.description.abstractalgorithm can be easily added for the sake of evaluation and
dc.description.abstractverification. The feasibility of relaxing some assumptions included
dc.description.abstracttherein, such as the hidden node problem in a two dimensional space,
dc.description.abstractmay also be studied to make the platform closer to a real system.
