The abstract is to be in Vehicular ad-hoc networks (VANET) belonging to family of ad-hoc uses IEEE 802.11p standard which have received considerable attention in many vehicular projects and industry groups. VANETs are a special kind ofmobile Ad-Hoc networks where wireless-equipped (road-side) vehicles form a network with no additional infrastructure. While many communication scenarios exist for these networks, InVANET project focuses on the application to improve vehicular safety by taking into account the physiological and ecological context-aware / sensitive parameters to increase driver convenience. The aim ofthis research work is to focus on design of a middleware architectural model for providing safety in "high-speed mobile" vehicles forming a network. Even though a number of passive safety approaches exist, incorporating active safety (intelligence) is challenging part of this work. This research paper discusses on design, functionality and working architecture of InVANET and the test-bed is being simulated over IEEE 802.11 VANET nodes. ©2009 IEEE.
