可见光通信与WiFi异构网络联合资源分配策略及切换机制研究

The next generation high speed WLAN aims to realize high data rate by developing new spectrum resources, and effectively improve the performance of heavy load networks. Visible light communication provides a high capacity solution to alleviate the wireless spectrum crunch. This project aims to address the challenge of resource management in heterogeneous VLC and WiFi networks, focusing on the network resource allocation and handover scheduling. The joint resource allocation technique in hybrid VLC and WiFi system will be studied, for optimal resource assignment scheme. Then, the joint handover scheme for the hybrid networks will be designed, especially flexible and simple handover decision algorithm. Finally, the heterogeneous networks based on the joint handover scheme will be experimentally demonstrated. The proposed novel indoor network is expected to satisfy the large-capacity communication needs of population-intensive areas and provide new exploration for the last mile.

下一代高速无线局域网希望通过开发新的频谱资源进一步提高传输速率，有效提升室内外密集网络部署环境下的性能。可见光通信为无线局域网络的“频谱紧张”、“深度覆盖”等问题提供高速大容量的解决方案。本项目针对可见光通信与WiFi异构融合网络中亟待解决的资源管理问题进行研究，将异构网络的资源管理问题转化为资源分配和切换调度两个子问题。主要研究内容为：研究可见光通信与WiFi异构网络的联合资源分配策略，获取最优化的资源调度方案；提出可见光通信与WiFi异构网络的联合切换算法，解决高灵活性、低复杂度的切换判决方案这一难点问题；并对采用联合切换算法的可见光通信与WiFi异构网络进行实验验证。本项目构建的新型室内网络能够满足人口密集区大容量的通信需求，为“最后一公里”的实现提供新的发展方向和动力。
