混合光无线网络被认为是一种很有前途的解决方案，以满足日益增长的用户带宽和移动性的需求。由于光和无线技术的基本差异，一个具有挑战性的问题在于媒体访问控制（MAC）协议的设计，使其能够支持严格的服务质量（QoS）的要求。在本文中，我们描述和评估的资源管理框架设计的如何网络。在资源管理框架中有两个部分，第一部分是增强的MPCP（E-MPCP）方案，旨在提高光网络和无线网络之间的信令能力。第二部分是一个综合的光无线接纳控制（IOW-AC）计划，旨在提供综合的带宽分配在HOW网络。我们的研究结果表明，在吞吐量，延迟和数据包丢弃概率的系统性能取决于几个因素。这些因素包括帧持续时间、业务负载和共享用户的总数。结果还强调，我们提出的系统实现了显着的改进，在用户QoS保证和网络资源利用率方面的传统方法。
The hybrid optical wireless (HOW) network has been viewed as a promising solution to meet the increasing user bandwidth and mobility demands. Due to the basic differences in the optical and wireless technologies, a challenging problem lies in the Media Access Control (MAC) protocol design so that it can support stringent Quality of Service (QoS) requirements. In this paper, we describe and evaluate a resource management framework designed for the HOW networks. There are two parts in the resource management framework The first part is the Enhanced MPCP (E-MPCP) scheme aiming at improving signaling ability between the optical and wireless networks. The second part is an Integrated Optical Wireless Admission Control (IOW-AC) scheme aiming at providing the integrated bandwidth allocation in the HOW networks. Our results show that the performances of the system in terms of throughput, delay and packet dropping probability depend on several factors. These factors include the frame duration, the traffic load and the total number of shared users. The results also highlight that our proposed system achieves significant improvements over the traditional approach in terms of user QoS guarantee and network resource utilization.
