Executive Summary

There are existing two types of ad hoc networks in mobile communications, called Mobile Ad Hoc Network (MANET) and Vehicular Ad Hoc NETwork (VANET). Out of these, Vehicular Ad Hoc Network (VANET) is more popular wireless ad hoc network. It is based on IEEE 802.11 wireless standard, which facilitates vehicle to vehicle and vehicle to roadside communications through air interface. Federal Communications Commission (FCC) suggests for VANET frequency spectrum (bandwidth) of 75 MHz in the range of 5.850 GHz to 5.925 GHz. In this bandwidth seven channels are fragmented, having each 10 MHz bandwidth, in which six channels are used for services and one channel is used for control purpose like broadcast services, e.g., safety message, announcement, etc.
