自由空间光通信可以提供快捷、方便的宽带访问,文章讨论了进行自适应光无线链路设计需要考虑的各种因素。链路恢复技术中的动态负载交换算法实现了FSO和RF间的负载交换,确保在不同传输损耗下的服务质量。区域划分法实现了在多跳网状网络下的业务量均衡,从而较好地解决了链路失效的问题。 Free space optical communications provide fast and easy broadband access and the article discusses various factors to consider for designing an adaptive optical wireless link. The dynamic load switching algorithm in the link recovery technique enables the exchange of load between the FSO and the RF to ensure the quality of service at different transmission losses. The regional division method realizes the traffic balance under the multi-hop mesh network, and thus solves the problem of link failure.
