Intelligent Transportation System (ITS) has enjoyed a tremendous growth in the last decade and the advancement in communication technologies has played a major role behind the success of ITS. Due to the nature of communication in vehicular environments, wireless access is considered as an integral part of any ITS system. The IEEE 1609.4 has evolved as a standard for Wireless Access for Vehicular Environment (WAVE), which describes multichannel access operations over the 5.9GHz Dedicated Short Range Communications (DSRC) spectrum. Communication channels in the 1609.4 are grouped into service and control channels.
