Dynamic route planning is one of the ITS efficiency applications that reduce travel time and energy consumption. To perform efficient route planning, real-time traffic information should be collected and disseminated to vehicles on other road segments. vehicular ad-hoc networks (VANETs) are a promising technology that can provide the communication means to deliver the required traffic information. In this paper, we study and evaluate three state-of-the-art dissemination protocols in realistic vehicular scenarios. The evaluated protocols are geocast-based beacon piggybacking protocol, a low-overhead adaptation of it and greedy perimeter stateless routing (GPSR). As performance metrics we measure the average end-to-end delay, average routing overhead and the packet delivery ratio as a function of traffic density. The goal is to find a reliable dissemination protocol that fulfills the application requirements and requires low routing overhead. Simulation results show that all three protocols achieve the requirements of dynamic route planning in end-to-end delay and packet delivery ratio. However, a significant reduction in the routing overhead can be achieved by the modified piggybacking protocol.
