![]() ![]() This algorithm works according to different TDMA slots (those are treated as levels) in order minimize the congestion in FiWi Networks, so it can help to minimize the queuing delay performance. The real time data is placed into the queue which is having the highest priority queue, while the non-real-time data is placed into other two queues depending on the threshold values set for them. In proposed method, every ONU is configured with three levels of priority queues. The innovation of the proposed method compared to previous methods provides a complete multilevel framework for reducing delays to an acceptable level. To solve the problem of increasing delay in FiWi networks due to increasing number of users, connection patterns and traffic congestion, in this work we proposed a multilevel, multi-queue based DBA method, so it is called Multilevel Multi-queue DBA. Hence, it is required to have efficient queuing method at ONU to allocate bandwidth efficiently to get high speed performance of FiWi one of such methods is called as Dynamic Bandwidth Allocation (DBA). Increasing queuing delay resulted into decreasing the throughput performance of FiWi networks. ![]() But the major problem with these networks is as the number of mobile user’s increases, queuing delay is increasing at FiWi’s Optical Network Unit (ONU). ![]() FiWi supports the mobility of wireless networks as well as high bandwidth of optical networks. The recent solution for this is used by Fiber-Wireless (FiWi) network which it can provide the high throughput for end users. In recent years demand for high speed and robust wireless networks are increasing due to the growth of accessing social networks from mobiles and computer systems. We explore ways of how they can be deployed across relevant economic sectors other than telecommunications per se, taking major paradigm shifts such as the Third Industrial Revolution, Energy Internet, smart grid, and explosion of mobile data traffic in today’s cellular networks into account. Given that most 4G cellular mobile network researches so far have been focusing on the achievable performance gains in the wireless front-end only without looking into the details of backhaul implementations and possible backhaul bottlenecks, we identify open key research challenges for FiWi broadband access networks. Furthermore, we discuss service, application, business, and operation related aspects, which motivate access technology to move into a substantially different direction in the long run than continued capacity provisioning. After describing the beginnings and state of the art of integrated fiber-wireless (FiWi) broadband access networks in great detail, we briefly review recent progress and point to various ongoing research activities, including the design of energy-efficient “green” FiWi access networks, advanced survivability techniques, and integration of wireless and fiber optic sensors, towards realizing adaptable, dependable, and ecoconscious future-proof broadband access networks based on both wireless and shared passive fiber media. ![]()
