Abstract

We propose a rank-based network coding scheme for distributing content in vehicular ad-hoc networks, in which vehicles adaptively broadcast packets based on the content reception status of their neighbors. In contrast to the previous work, CodeOn, vehicles in the proposed method only exchange content reception information in the service channel. The packet injection probability in the proposed method is proportional to the estimated innovation that a vehicle can provide to its neighbors. We also give an analytical model to analyze the system throughput when vehicles apply rank-based network coding to broadcast data. Simulation results demonstrate that the proposed method improves the throughput by more than 32% while maintaining lower end-to-end delay and protocol overhead than the previous work.
