“…However, for fast-moving devices, the ECMCC problem should be redefined by considering multiple connectivity of UEs to different BSs. Li et al 20 have categorized wireless groups into "video-hot" groups with great interest in VoD services and "video-cold" groups with infrequent video requests. For video requests from "video-hot" groups, we first propose an energy-efficient ONU selection approach to reduce ONU power consumption by selecting a subset of ONUs to support such requests, our previously proposed rebroadcast and patching scheme can be effectively applied.…”

Hybrid fiber wireless (FiWi) access networks seek to combine the vast amount of bandwidth that is available for optical networks and wireless network mobility; hence, it favors larger bandwidth request but cause the highly nonlinear lagrangian dual problem that decrease energy‐efficient network resilience. Hence, a novel Ceplato‐SAT3 model has been proposed in which the SAT3 algorithm locates the optical network unit (ONU) in an optimal position with high‐speed cost‐efficient placement and weight factor introduced into the position update to improve the exploitation and exploration capability of the algorithm. To prioritize the large bandwidth request during resource allocation, gradient priority justifier requests (GPJR) has been utilized and a novel messaging technique termed flow‐random‐message‐exchanger‐topology (FRMET) provides the index for these prioritized requests depending on QoS parameters such as notification control, reflective QoS attribute (RQA), flow bit rates and maximum packet loss rate thereby decreasing the overhead and eliminate nonlinear langrage dualand perform O2U scheduling to reduce network resilience however synchronization between different ONU clocks may cause upstream data fatal crash at the optical line terminal (OLT). Hence, curl‐trio‐opt control mechanism has been proposed in which the minimization problem is transformed into a joint optimization problem of energy consumption, traffic demand, network requests, and service flow requests by the Lyapunov technique thereby minimizing the upstream data fatal lash. The proposed model has been implemented in Python and the output obtained showed better performance in terms of ONU arrangement, throughput, energy consumption, computation, latency, and error.

“…In [12], an energy-efficient multicast scheduling scheme was proposed to maximized the network throughput, including online admission control, basic layer data scheduling and enhancement layer data scheduling. In [13], the authors evaluate the video transmission performance in terms of the worst play delay and proposed a batch processing broadcast mechanism for non-hotspot users while ensuring the demand of hotspot users. In [14], a linear prediction algorithm was proposed to achieve the current network conditions, based on which a QoS-aware video transmission mechanism was further studied.…”

In this paper, a video multicast mechanism is studied in fiber-wireless (FiWi) access networks with object to guarantee the quality of experience (QoE) for different users. Firstly, according to the characteristics of scalable video coding, a new QoE evaluation model is built in terms of the video interruption probability, video bitrate and smoothness. Then the optimal transmission path is studied based on the coverage and transmission capabilities of ONU-BS nodes. Specifically, a bipartite graph is constructed based on which the multicast tree is obtained by solving the minimum dominating set problem. Thereafter, a video bitrate adjustment algorithm is proposed to reduce the video interruption probability based on the buffer state on the user side and meet the bitrate requirements for different users during multicast transmissions. Simulation results verify that the proposed scheme performs well in QoE guarantees for different users simultaneously.INDEX TERMS Fiber-wireless access networks, scalable video coding, quality of experience, multicast adaptation.
