Latency Estimation-Based Data Delivery Scheme for Vehicular Ad Hoc Networks

Data delivery is the most compelling issue for the applications in vehicular ad hoc networks. The characteristics of VAENTs such as highly dynamic topology and the road-constrained mobility pose great challenges for data delivery in vehicular ad hoc networks. In this paper, a Latency Estimation-based Data delivery (LED) scheme is presented. According to the current location and the moving direction of the vehicles, LED calculates the Expected Delivery Latency (EDL) of each vehicle and chooses the vehicle with the shortest EDL as the next hop to forward data. Simulation results show that LED performs better than VADD.
