Multi-scene Adaptive Broadcasting Optimization Algorithm in VANETs

摘要

Important information such as emergency warning need to be broadcasted in VANETs. Therefore, an effective broadcasting method is necessary, but broadcasting optimization based on single network state can't adapt to the complex VANET environment. In this paper, a Multi-scene Adaptive Broadcasting Optimization (MABO) algorithm is proposed, and it adaptively selects more suitable state parameters to optimize broadcasting when the scene has changed. Simulation results show that MABO not only can guarantee node reachability, but also can reduce broadcast redundancy and transmission delay in multi-scene network environment.
