During the last two decades, the IEEE 8201.11 family has multiplied data rate transmissions in wireless local area networks (WLANs). This progress is based on the adoption of new technologies concerning physical layer (PHY), combined with the enhancements in the medium access control (MAC) layer. Radio over Fiber (RoF) is a technology which can further extend this progress, combining the benefits of optical fiber and wireless networks. The current IEEE 802.11 MAC protocol is contention based, which leads to low utilization of the RoF PHY data rate and on the other hand cannot handle the effects of long propagation delays in RoF networks. In this paper, we present a new Hybrid Link Time Division Multiple Access (HL-TDMA) MAC protocol which addresses the above shortcomings and enhances the performance of both conventional and RoF WLANs. Then, through simulation, we evaluate the performance of the proposed protocol, which is shown to be superior to relevant RoF WLAN protocols in the literature.

常规和光纤WLAN的混合链路TDMA MAC协议

在过去的二十年中，IEEE 8201.11系列在无线局域网（WLAN）中的数据速率传输倍增。这一进步是基于采用了有关物理层（PHY）的新技术，并结合了媒体访问控制（MAC）层的增强。光纤无线电（RoF）是一项技术，可以结合光纤和无线网络的优势，进一步扩展这一进步。当前的IEEE 802.11 MAC协议是基于竞争的，这导致RoF PHY数据速率的利用率低，另一方面，无法处理RoF网络中长传播延迟的影响。在本文中，我们提出了一种新的混合链路时分多址（HL-TDMA）MAC协议，该协议解决了上述缺点并增强了常规和RoF WLAN的性能。然后，
