A Multi-channel Cooperative Demand-Aware Media Access Control Scheme in Vehicular Ad-Hoc Network

The application of VANET can be divided into two types: security and non-security. Non-secure applications are primarily used to provide entertainment information. Secure applications will provide information to the driver in advance. Therefore, the delay and reliability of communication are strictly required for secure applications. In this paper, we propose a kind of demand-aware medium access control protocol based on multichannel cooperation in vehicular ad hoc networks. First, the scheme uses RSU (the roadside unit) to broadcast the secure query packets, and the node sends the emergency information of the vehicle node through the advance reservation control slot. Then, time slot will be divided dynamically according to the demand of the secure data, and each node will be coordinated by RSU to reduce the collision probability and safe data packet delay. The simulation results show that the proposed medium access control scheme can improve the network throughout and reduce the end-to-end transmission delay compared with the traditional 802.11p protocol.
