The IEEE 802.11ad-based wireless local area network (WLAN) has emerged out as a promising network technology that is capable of operating on millimetre wave spectrum. This network is being used in many applications and can be extended to serve many different streams of the networking industry. However, the network still has some glitches with respect to throughput, overhead, etc., which need to be handled to make it more reliable and efficient. In this paper, distributed directional cooperative medium access control (DD-CoopMAC) protocol for improving variable bit rate (VBR) throughput in IEEE 802.11ad WLAN is proposed. In this protocol, information about network stations is intelligently collected; based on this, the relay stations are selected for transmission. Simulation results illustrate that this protocol aids in enhancing the throughput and reducing the related overhead. Also, simulation results show that the proposed DD-CoopMAC has given high throughput and less MAC delay compared with D-CoopMAC and IEEE 802.11ad.

基于IEEE 802.11ad的无线局域网（WLAN）已经成为一种有前途的网络技术，能够在毫米波频谱上运行。该网络正在许多应用中使用，并且可以扩展以服务于网络行业的许多不同流。但是，网络在吞吐量，开销等方面仍然存在一些故障，需要对其进行处理以使其更加可靠和高效。本文提出了一种用于提高IEEE 802.11ad WLAN可变比特率（VBR）吞吐量的分布式定向协作媒体访问控制（DD-CoopMAC）协议。在该协议中，将智能地收集有关网络站点的信息；基于此，选择中继站进行发送。仿真结果表明，该协议有助于提高吞吐量并减少相关开销。仿真结果还表明，与D-CoopMAC和IEEE 802.11ad相比，所提出的DD-CoopMAC具有较高的吞吐量和较小的MAC延迟。
