Abstract
The present disclosure discloses a method for Internet of Vehicles (IoV) electronic traffic sign information broadcast with Quality of Service (QoS) guaranteed mechanism based on conflict detection. Compared with the traditional WLAN applied in electronic traffic sign information broadcast, the present disclosure significantly reduces the information broadcast delay, and at the same time provide QoS guaranteed service for the information broadcast. It allows IoV, through distributed algorithm, to achieve the electronic traffic sign information broadcast with self-organization framework, short transmission delay and high efficiency.
