ABSTRACT
The advancement in WLAN technologies and introduction of WAVE standards, motivated researchers in the area of Vehicular ad hoc networks (VANETs). VANETs are special kind of ad hoc networks having the characteristics of fast topology changes and high node mobility. Commitment of various governments to allocate dedicated wireless frequency spectrum for VANETs and sensitivity towards safety in road navigation, further accelerated the interest in vehicle to vehicle communication (V2V) and vehicle to infrastructure communication (V2I). A vehicular ad-hoc network is the cooperative engagement of a collection of mobile nodes without the required intervention of any existing infrastructure. The successful delivery of radio packets within stipulated time period, is very challenging in this constrained situation. In this article, we discuss various types of routing strategies and survey the various routing protocols and associated mobility models for VANETS.
