摘要
提出了一种新型的基于自组网车载通信系统的MAC协议。该协议采用竞争与预约相结合的方法,有效地解决了隐藏、暴露终端等问题。仿真结果表明该协议能够保证节点快速可靠地接入信道,而且对网络规模不敏感。
In the paper, a new MAC protocol in vehicle communication system based on ad hoc network is presented. The protocol, which combines contention and reservation, solves hidden, exposed terminal problems perfectly. The simulation results show that the protocol can guarantee a node to access channel rapidly and reliably, moreover, it is not sensitive to the scale of networks.
