摘要: More than 23% of annual vehicle accidents are rear-end collisions, which provides an important test-case for enhanced collision avoidance approaches based on v2v wireless communications. In this work, we propose and study the impact a 802.11 multi-hop MAC protocol that propagates emergency warning message (EWM) down platoon cars highway. The design objective is to ensure reception with stringent (low) delay constraints so as provide drivers requisite available maneuver time (AMT) avoid collision. We realistic simulation studies performance within ns-2 environment various topology (1 lane 3 lanes) background traffic scenarios, well different parameter settings, highlight potential approach effective or mitigation.
