Abstract
Ultraviolet (UV) optical communication can eliminate aiming, tracking, and pointing systems in conventional free-space optical (FSO) communications, rendering it more suitable for small and micro platforms. Currently, efficient medium access control (MAC) layer protocols for UV optical communication are lacking. To further improve the channel utilization of UV networks, an ultraviolet lossless contention MAC protocol with dynamic bandwidth allocation (UVLLC-DBA) based on optical power superposition was proposed. Simultaneously, the protocol employed token buckets to allocate bandwidth for different services, thereby enabling differentiated services. The simulation results show that the proposed protocol can achieve dynamic bandwidth allocation and has nearly 100% channel utilization and acceptable delay, providing a reference for the development of a UV MAC protocol.
紫外（UV）光通信可以消除传统自由空间光通信（FSO）中的瞄准、跟踪和指向系统，因此更适用于小型和微型平台。目前，紫外光通信还缺乏高效的介质访问控制（MAC）层协议。为进一步提高紫外网络的信道利用率，提出了一种基于光功率叠加的动态带宽分配紫外无损争用 MAC 协议（UVLLC-DBA）。同时，该协议采用令牌桶为不同服务分配带宽，从而实现了差异化服务。仿真结果表明，所提出的协议可实现动态带宽分配，信道利用率接近 100%，延迟可接受，为开发 UV MAC 协议提供了参考。
期刊介绍：
The scope of the Journal includes advances in the state-of-the-art of optical networking science, technology, and engineering. Both theoretical contributions (including new techniques, concepts, analyses, and economic studies) and practical contributions (including optical networking experiments, prototypes, and new applications) are encouraged. Subareas of interest include the architecture and design of optical networks, optical network survivability and security, software-defined optical networking, elastic optical networks, data and control plane advances, network management related innovation, and optical access networks. Enabling technologies and their applications are suitable topics only if the results are shown to directly impact optical networking beyond simple point-to-point networks.
