Abstract— Vehicular Ad hoc Network is a special class of Mobile Ad hoc Network which follows infrastructure less network. For broadcasting the message, the system deals with Distribution-Adaptive Distance with Channel Quality (DADCQ) protocol. It performs well on using distance method to forward nodes. The performance depends on wide variability in node density, pattern distributed, and Quality of Channel. DADCQ protocol addresses the problem by selecting decision threshold value by distance method. The success and the performance of the system depend on the threshold value selected. Whenever the mobile nodes are moving out of the region, the nodes will loss the data of the particular region. This happens in entire mobile environment. It can be reduced by using Position Based Routing Protocol. So, the proposed concept will provide better solution for the vehicular environment.

Keywords— VANET, Node density, Quality of Channel.
