网络密集化导致的冲突和干扰的增加对提高网络吞吐量提出了棘手的挑战。信道预留和协作传输作为提高媒体接入控制（MAC）效率和传输可靠性的两种方案，受到了广泛的关注。在我们最近的研究中，理论上证明了预留和协作的联合优化在提高网络吞吐量方面是有前途的。然而，到目前为止，没有实际的MAC协议被提出来评估其有效性。本文提出了一种基于ALOHA的联合预留与协作MAC（AJRC-MAC）协议，该协议采用基于预留的信道接入，并支持密集无线网络中的同时协作传输。仿真结果表明，与基本MAC、协作MAC和预约MAC相比，AJRC-MAC的吞吐量分别提高了330%、250%和130%。
The increase in collision and interference induced by the network densification poses the intractable challenge of improving network throughput. Channel reservation and cooperative transmission, two schemes improving the medium access control (MAC) efficiency and transmission reliability respectively, have drawn considerable attention. Joint optimization of reservation and cooperation is theoretically proved to be promising in improving the network throughput in our recent study. However, up to now no practical MAC protocol is proposed to evaluate its effectiveness. In this paper, we propose an ALOHA-based joint reservation and cooperation MAC (AJRC-MAC) protocol which adopts the reservation-based channel access and enables the cooperative transmission simultaneously for the dense wireless network. Simulation results evaluate the effectiveness of the joint reservation and cooperation, and show that a throughput gain of 330%, 250%, 130% can be achieved respectively for AJRC-MAC compared with the basic MAC, cooperation- only MAC and reservation-only MAC.
