Effects of Optical Network Unit Placement Schemes for Multi-Channel Hybrid Wireless-Optical Broadband-Access Networks

Abstract- Wireless-optical broadband-access networks (WOBAN) present a promising solution for meeting the growing customer demands in access networks. In this paper, we address the optimal placement of optical network units (ONUs) in a WOBAN to improve its performance and reduce the fiber cost. We propose a solution for ONU placement that employs a clustering technique to distribute the ONUs across the network, for a given distribution of wireless mesh routers. We also explore the effect of routing and channel assignment on top of the ONU placement schemes. Performance evaluations from simulations are presented
