Implementation of VANET routing using computational intelligence

Vehicular Ad hoc Networks (VANETs) is an emerging technology that allows vehicles on roads to form a self-organized network without the aid of a permanent infrastructure. VANETs have received increasing research attention in recent years because of its vast applications. They play a significant role in enhancing safety, comfort and entertainment. Vehicle to vehicle (V2V) and Vehicle to Infrastructure are the two types of communications supported by VANETs. VANETs can use a wide range of routing algorithms as per requirement of need or situation for transmission of data. This paper is an attempt to document the routing challenges of VANETs. Performance evaluation of routing algorithms under realistic models is done by simulation. The simulator used is NS2. To evaluate the performance different node density is used. Different scenarios are tested with realistic mobility models. Ant Colony algorithm implementation is done for solving routing problems of VANET.
