Availability-Aware Routing for Large-Scale Hybrid Wireless-Optical Broadband Access Network

In large-scale hybrid wireless-optical broadband access networks, the availability of wireless links and optical links varies considerably. Availability-aware routing can significantly improve availability and throughput by encouraging more usage of PON. Hybrid Wireless-Optical Broadband Access Network (WOBAN) consists of a multi-hop Wireless Mesh Network (WMN) at the front-end and an optical access network, e.g., a Passive Optical Network (PON) at the back-end. PON uses inexpensive optical splitters to divide a single fiber into separate strands feeding individual subscribers. EPON is based on the Ethernet standard, which comes with the added benefit of the economies-of-scale of Ethernet, and provides simple and easy-to-manage connectivity both at the customer premises and at the central office.
