Wireless access is needed to serve rural and urban sectors in the developing nations, while simultaneously encompassing both data and voice traffic in the same core network. We propose an architectural design of Multiservice Provisioning Platform (MSPP) for WiMAX over SONET/SDH, which involves interworking conventional technologies to deliver a solution that caters to unique situations that favor wireless access network over fully cabled systems. It consists of Wireless Access Network design, 2-way interlinking section, and the MSPP – optical core Network. It enhances the versatility of the MSPP and uses the SONET/SDH core network efficiently.[1]

Wireless Access Network

: Fiber Wireless Access Network is the blend of passive optical network and wireless access network. This network provides higher capacity, better flexibility, more stability and improved reliability to the users at lower cost. Network component (such as Optical Network Unit (ONU)) placement is one of the major research issues which affects the network design, performance and cost. Considering all these concerns, we implement customized Whale Optimization Algorithm (WOA) for ONU placement. Initially whale optimization algorithm is applied to get optimized position of ONUs, which is followed by reduction of number of ONUs in the network. Reduction of ONUs is done such that with fewer number of ONUs all routers present in the network can communicate. In order to ensure the performance of the network we compute the network parameters such as Packet Delivery Ratio (PDR), Total Time for Delivering the Packets in the Network (TTDPN) and percentage reduction in power consumption for the proposed algorithm. The performance of the proposed work is compared with existing algorithms (deterministic and centrally placed ONUs with predefined hops) and has been analyzed through extensive simulation. The result shows that the proposed algorithm is superior to the other algorithms in terms of minimum required ONUs and reduced power consumption in the network with almost same packet delivery ratio and total time for delivering the packets in the network. Therefore, present work is suitable for developing cost-effective FiWi network with maintained network performance.
