Abstract EN
In VANET (vehicular ad hoc network) environment, the successive vehicle position data actually are discrete, so the key to the moving vehicle modeling is to effectively reduce the updating frequency of the position data so as to alleviate the communication and database management load.
This paper proposes vehicle position data updating strategy with packet repetition based on Kalman filter predicting.
Firstly, we design a position data updating model based on Kalman filter difference predicting equations.
Then, we design a packet repetition mode decision algorithm, which is applied to deliver vehicle position updating data.
The model with packet repetition can not only generate position updating data according to preset threshold, but also decide packet repetition mode related to the distance of two adjacent vehicles in order to reduce data loss.
Both simulated highway and realistic urban road experimental results show that vehicle position data updating frequency could be obviously reduced and the reliability of the communication is greatly improved through packet repetition mechanism by using this position updating strategy.
