Research of Hybrid Positioning Based Vehicle Interactive Navigation System

Safety is one of main goals of VANET (Vehicular ad hoc Network). In Vehicle Interactive Navigation System, according to vehicle-to-vehicle (V2V) communications vehicle can share its own location within the lane and other information (speed, velocity, acceleration) to the neighboring vehicles so that it allows vehicles to coordinate maneuvers for safety goal such as collision avoidance. Traditionally, GPS is employed to position the vehicle location. However, the accuracy of GPS alone system is not enough to meet safety requirement. Then, we propose a hybrid positioning model to enhance accuracy of position which combines GPS and RSSI based localization technology by using acceleration sensor and Zigbee wireless technology.
