摘要:
车载自组网基于竞争的MAC协议IEEE 802.11P存在预见性、公平性、低吞吐量、延迟性、高碰撞率等问题。 提出基于集群协作的MAC协议CCBM(an cooperative cluster-based MAC protocol for VANETs),解决节点接入信 道的公平性问题,同时提高信道的利用率和有效地适应网络拓扑变化。理论计算和仿真结果显示,选择集群头节点 HN(head node)的平均时隙小于IEEE 802.11P 50%,稳定性增加50%。
Abstract:
For vehicular ad-hoc network(VANET), contention-based medium-access-control(MAC)protocols such as IEEE 802.11p have problems in predictability, fairness, low throughput, latency, and high collision rate.Therefore, this paper proposes a new protocol,i.e. An Cooperative Cluster-based MAC Protocol for VANETs(CCBM). Therefore, CCBM solves the fairness problem of node access channel. In addition, the group's algorithm can also improve the utilization of idle time, and it can effectively adapt to network topology changes. Theoretical calculation and simulation results show that the average time slot of the head node(HN)is less than IEEE 802.11P 50% and the stability is increased by 50%.
