The ever increasing demand in wireless connectivity has led PON networks suffer from limitations in mobility and wide area coverage. Wireless networks suffer by bandwidth limitations. Hybridization uses the best characteristics of all networks: wireless networks and optical networks. A lightweight wireless mesh network is a wireless-optical broadband access network (WOBAN), which has a front end and background effective bandwidth optical network. WOBAN has already suffered from two large network feature faults as well as feeder and fiber breaks. Cluster-based protection (CBP) mechanism is proposed in order to increase traffic recovery reliability and reduce backup fiber deployment. With minimal fiber distribution cost, CBP efficiently manages single and simultaneous failures from many segments. Long-term evolution (LTE) technique-based CBP is implemented in WOBAN. Faults are analyzed by injecting wireless/distribution fiber/multiple feeder fiber. The novel fault tolerant network is built using an efficient automated failure detection and rerouting (AFDRR) algorithm. An efficient automated failure detection and rerouting (AFDRR) algorithm is used for developing the novel fault-tolerant network. Implementation of orthogonal frequency division multiplexing (OFDM) technology-based AFDRR-CBP on WOBAN-LTE network with the same scenario is analyzed through simulation. The performance measures are compared among CBP-WOBAN-LTE network, AFDRR-CBP-WOBAN-LTE network, and OFDM-based AFDRR-CBP-WOBAN-LTE networks. From the result obtained, it will be revealed that the suggested methodology throughput ratio will increase up to 24.4% when compared to other methodology.

具有集群控制架构的容错无线光宽带接入网络

对无线连接不断增长的需求导致 PON 网络在移动性和广域覆盖方面受到限制。无线网络受到带宽限制的影响。混合使用所有网络的最佳特性：无线网络和光网络。轻量级无线网状网络是无线光宽带接入网络（WOBAN），它具有前端和后台有效带宽光网络。WOBAN 已经遭受了两个大型网络功能故障以及馈线和光纤中断。为了提高流量恢复的可靠性，减少备份光纤的部署，提出了基于集群的保护（CBP）机制。CBP 以最低的光纤分配成本有效地管理来自多个网段的单个和同时发生的故障。WOBAN 中实现了基于长期演进 (LTE) 技术的 CBP。通过注入无线/分布式光纤/多馈线光纤进行故障分析。新型容错网络是使用高效的自动故障检测和重新路由 (AFDRR) 算法构建的。一种高效的自动故障检测和重新路由 (AFDRR) 算法用于开发新型容错网络。通过仿真分析了基于正交频分复用(OFDM)技术的AFDRR-CBP在WOBAN-LTE网络上的相同场景的实现。性能指标在 CBP-WOBAN-LTE 网络、AFDRR-CBP-WOBAN-LTE 网络和基于 OFDM 的 AFDRR-CBP-WOBAN-LTE 网络之间进行了比较。从获得的结果可以看出，建议的方法吞吐率将增加到 24。
