RUFS: RobUst Forwarder Selection in Vehicular Content-Centric Networks

Vehicular Content-Centric Network (VCCN) has emerged as a future network technology for vehicular networks, where the focus of communication is shifted from the host to information centric. However, VCCN faces several challenges, including interest/data packet(s) flooding, provider/consumer mobility, and so on. In this letter, we propose a scheme named RobUst Forwarder Selection (RUFS) to mitigate the interest broadcast storm. In RUFS, each vehicle shares its satisfied interest(s) statistics with neighbors. All neighbors store this information in their Neighbors Satisfied List (NSL), which helps to select the potential interest forwarder. Simulation results show that RUFS outperforms the recently proposed NAIF, DR based and basic interest forwarding in VCCN.
