| Summary: | Vehicular sensors capture a large amount of data, and a routing algorithm is needed to effectively propagate the data in vehicular sensor network (VSN). The existing routing algorithms in vehicular ad hoc network (VANET) can not be transplanted to VSN directly. After analyzing the mobility of vehicles, we find that the delivery time of vehicle to vehicle (V2V) or vehicle to infrastructure (V2I) is very short especially when a deliverer is at a corner or crossroad and tries to deliver data to its left/right direction. Using existing routing algorithms in VANET will cause the big amount of data to stuck at corners or crossroads and to be transmitted back and forth with very few data packets being delivered. It is very time consuming and computation consuming. In this paper, we propose a data delivery algorithm called distribution-based data delivery to handle the above-mentioned corner problem with the help of some vehicular sensors like accelerometer. Evaluations show that the time cost of data delivery at corners is saved for at least 30% by our algorithm comparing to other routing algorithms like VADD in VANET. |
