Abstract
In Vehicular Ad Hoc Networks (VANETs), there exist a variety of applications which rely on Infrastructure-to-vehicle (I2V) communication. A large number of studies have recently been conducted to investigate I2V data forwarding and trajectory-based delivery schemes to deliver the message. Trajectory-based I2V delivery schemes use the vehicle trajectory information to select a rendezvous point of the message and the vehicle. The message will be forwarded to the rendezvous point before the vehicle arrives. Since the vehicle passes through this point, it can thus receive the message. However, most trajectory-based delivery schemes do not consider the circumstances that the vehicle may detour because of the road construction or car accident in the real world. In this work, we propose an analytic model to recursively derive the probability which the vehicle can successfully receive the message at the selected rendezvous point considering the vehicle may detour during the movement. Besides, we also develop a simulation model to validate against our analytic model. Our analytic and simulation models both can provide for trajectory-based delivery schemes to estimate the message reception probability which the vehicle receives the message even under the vehicle detour.
