    Deployment of Fi-Wi Networks Using Teaching Learning Based Optimization Algorithm

    By Uma Rathore Bhatt, Nitin Chouhan, Raksha Upadhyay, Chanchal Agrawal

    Abstract: AbstractThe demand of bandwidth and mobility to end users is ever increasing. For fulfilling this, fiber-wireless (Fi-Wi) networks are designed by integrating the advantages of optical and wireless networks. Optical networks offer high bandwidth and stability while wireless networks offer cost efficiency and mobility. With these advantages, Fi-Wi networks also offer some challenging issues. There are four key issues in Fi-Wi networks, that are ONU placement, routing, energy saving and …

    An Energy Efficient Routing Algorithm for FiWi Access Network

    By Raksha Upadhyay, Uma Rathore Bhatt

    Abstract: AbstractFiber wireless access network is a promising access network due to the provision of higher bandwidth, flexibility, and ubiquity. One of the main challenges for a FiWi access network is to minimize energy consumption. In this network, there are many concerns like ONU placement, ONU sleep mechanisms, power saving mechanisms, etc., which are accountable for achieving energy efficiency. Routing is another aspect at the front end of the network, which …

    Multi-way Protection Scheme to Handle Multiple Failures for Cost-Efficient Fiber-Wireless (FiWi) Access Networks

    By Uma Rathore Bhatt, Tapesh Sarsodia, Raksha Upadhyay

    Abstract: AbstractFiber Wireless (FiWi) access networks prove themselves as promising broadband access networks. These networks enable users to access services in “Anywhere-Anytime” fashion. FiWi networks offer higher bandwidth and better flexibility at much lower price than passive optical network. As FiWi supports high data rate (typically about Gigabits per second), any failure may results in huge data loss. Therefore, to protect such loss of data, we need to design a more …

    ONU Placement and Restoration using Ant Colony Optimization Algorithm for Fiber Wireless Network

    By Uma Rathore Bhatt, Raksha Upadhyay, Aakash Chhabra

    Abstract: AbstractFusion of optical domain and wireless domain makes a new promising technology called as Fiber Wireless (FiWi) access network, which actually integrates the features of both in it. FiWi consists of passive optical network (PON) as optical backend which serves high bandwidth, high data rates etc. and wireless mesh network (WMN) as wireless frontend which provides the self-healing nature, high mobility and low cost. Various optimizing schemes for Optical Network …
