本文提出了一种基于时分多址的分布式媒体访问控制协议RBRP，用于移动自组网中的广播预约。RBRP的主要设计目标是在存在隐藏终端、预约死锁和移动性的情况下保证广播预约的健壮性。具体地，RBRP的特征在于四个重要特征：(I)两步信令过程，其中预留信令部分与帧的数据部分完全分离；(Ii)预留时隙内的多个微型时隙预留请求阶段，以防止死锁；(Iii)在每个数据时隙开始处的特殊信令，以适应拓扑变化；以及(Iv)优化以提高信道的空间重用，从而提高单播业务的利用率。使用ns-2中的一个详细的仿真模型，与IEEE 802.11分布式协调功能(DCFMAC)进行比较，评估了该协议的性能。仿真结果表明，对于广播和单播业务，在存在隐藏终端和移动性的情况下，RBRP的吞吐量比802.11 DCF提高了100%以上，而在全连接网络中具有相当的性能。
In this paper we present RBRP, a TDMA-based distributed medium access control (MAC) protocol for broadcast reservations in mobile ad hoc networks. The primary design goal of RBRP is robustness of broadcast reservations in the presence of hidden terminals, reservation deadlocks and mobility. Specifically, RBRP is characterized by four important features: (i) a two step signaling process in which the reservation signaling part is completely decoupled from the data portion of the frame; (ii) a multiple mini-slot reservation request phase within a reservation slot to prevent deadlocks; (iii) special signaling at the beginning of every data slot to adapt to topology changes and (iv) an optimization to improve the spatial reuse of the channel, and hence the utilization, with unicast traffic. Using a detailed simulation model in ns-2, we evaluated the performance of RBRP in comparison with the IEEE 802.11 distributed coordination function (DCF) MAC. Our simulation results show that RBRP achieves more than 100% throughput improvement over 802.11 DCF in the presence of hidden terminals and mobility, both for broadcast and unicast traffic, while having comparable performance in a fully connected network.
