Modified AODV Routing Protocol Using Artificial Swarm Intelligence Technique in VANET Communications

Two types of ad hoc networks in mobile communications are mainly existing; one is Mobile Ad hoc NETwork (MANET) and other one Vehicular Ad hoc NETwork (VANET). Vehicular Ad hoc NETwork (VANET) is highly demanded 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.
