“…Survivability is defined as the ability of the network to provide seamless connectivity and service provisioning after a failure [124]- [126]. This term has emerged as quite popular in hybrid wireless-optical network since it engages both optical protection, such as full or partial PON duplication [124], backup of fiber lines [127], and wireless protection, such as routing protection techniques assuming a wireless mesh infrastructure [128], [129]. Another interesting technique is the placement determination to facilitate safe routing paths and minimize the required number of equipment [130], [131].…”

The combination of the most prestigious optical and wireless technologies for implementing a modern broadband integrated access network has been progressively gaining ground. By extending the network coverage in a cost-efficient way, hybrid wireless-optical networks are able to enclose a larger number of potential subscribers than standalone access architectures. Hence, they are capable of increasing revenue levels and facilitating commercial penetration to the telecom market. At the same time, hybrid wireless-optical networks pose an ambitious, alternative, and efficient solution to coping with new bandwidth-hungry user applications. Hybrid wireless-optical networks incorporate sophisticated modules, fabrics, and network entities to effectively provide adequate quality of service (QoS) provisioning. This survey endeavors to classify the main features of wireless-optical integration. We provide a comprehensive compilation of the latest architectures, integrated technologies, QoS features, and dynamic bandwidth allocation (DBA) schemes. In addition, new trends towards wireless-optical convergence are presented. Moreover, as the up-to-date hybrid network standards remain under development, since there is not yet an integrated standard for approving hybrid network access platforms, we accompany this survey with detailed challenges indicating potential avenues of future research.

“…In each polling cycle of DOS, the manager will check current load of each ONU, if load of ONU u is o u load where u is index of ONUs. After that, the manager will do the following decisions according to the load of ONUs: (1) 2) and ( 3), nothing would be done.…”

“…PON allows network owing features of large capacity, long distance and high reliability as a result of its tree topology and optical fiber links. WMNs are flexible and low-cost [1] thus it is easy to deploy devices and achieve anywhere-anytime access for end users [2][3][4]. Therefore, FiWi access network is regarded as one of promising communication technology.…”

As one of promising "last mile" scheme for broadband access network, Fiber-Wireless (FiWi) access network has the advantages of high capacity, long distance, low cost etc because it is the integration of optical back-end and wireless front-end. At the same time, energy consumption of FiWi access network is an important factor that limits the development of networks. A number of ONU sleep states such as ONU power shedding state, ONU doze state, ONU deep sleep state and ONU fast sleep state have been proposed to obtain low-power ONU state, which indirectly reduce energy consumption of networks. However, these low-power states of ONU are born to coordinate to green Passive Optical Network (PON), of which the function of ONU is different from FiWi. In this paper, two low power ONU sleep mechanisms called Static ONU Sleep (SOS) mechanism and Dynamic ONU Sleep (DOS) mechanism, respectively, are proposed and embedded into FiWi access network. By simulation and analysis based on OPNET 14.5, this paper shows that the DOS mechanism has a better performance than SOS, and both of them can save energy of FiWi access network.
