Abstract

In this paper , based on the Vehicle-Assisted Data Delivery (VADD) routing algorithm [3] we present a new approach for the deployment of roadsice units (RSU) to improve the data delivery delay in VANET. The main concept of our approach is to add RSUs in intersections that can effectively improve the packet delivery delay. We will address the problem “How to decide which intersection needs to deploy RSU as a data buffer?”

The packet will buffer in a RSU and wait for a vehicle to carry it to the next hop. The RSU increases the opportunity to use wireless communication, decreases the chance to use carry and forwarding.

We have set up a simulation scenario and various traffic conditions to evaluate the performance. The simulation results show that the packet delivery ratio of proposed method has better performance than VADD about 5-10%. The delivery delay of our approach has outperformed than VADD about 15-20% on delivery delay.
