Executive Summary

Vehicular Ad hoc Networks is a form or type of mobile ad-hoc network to provide communication among nearby vehicles and nearby fixed equipments or roadside units for improving efficiency and safety of transportation. Even though it possesses characteristics of high node mobility and fast topology changes but still it can provide wide variety of services, ranging from safety related warning message system for improved navigation mechanism as well as information and entertainment applications. In this paper, the authors have studied various mechanisms or techniques along their comparison and limitation which were used to handle the communication challenges like congestion, delay, collision, redundancy while propagating emergency warning messages in Vehicular Ad hoc NeTworks (VANeTs).
