Hybrid wireless-optical broadband access network (WOBAN): network planning and setup

Hybrid algorithm: A cost efficient solution for ONU placement in Fiber-Wireless (FiWi) network

“…Sarkar et al [7][8][9][10][11] proposes various algorithms for ONU placement which include random approach, deterministic approach, greedy algorithm and simulated annealing (SA) algorithm. In random approach the network is divided into multiple nonoverlapping regions, and then ONUs are placed randomly in each region.…”

Comparative cost study of broadband access technologies

“…Hybrid Wireless-Optical Broadband Access Network (WOBAN) is a novel broadband access architecture which captures the best of both the optical and wireless worlds. WOBAN consists of a wireless network at the front-end supported by an optical backhaul, and can provide high bandwidth [3].…”

“…To deploy a PON, we assume that an OLT is placed in the city's (Davis) CO located in Downtown Davis. Optical fiber installation is expensive (USD 100,000 per mile in metropolitan area) [3], and it is reported that about 85% of this amount is tied to trenching and installing a new duct [3]. The rest (about 15%) of the expense involves the cost of new fiber and raw materials.…”

“…The rest (about 15%) of the expense involves the cost of new fiber and raw materials. In the US, an estimated 95% of localities are within 1-1.5 km of fiber-optic infrastructure [3]. Hence, we can assume that most of Davis is within the reach of fiber-optic ducts.…”

Forwarding Repeated Game for End-to-End QoS Support in Fiber-Wireless Access Networks

“…Therefore, having fiber as far as possible from the CO to the end users and then wireless at the front end can provide a flexible and cost-effective solution. Besides flexibility, such approach provides higher bandwidth than digital subscriber lines (DSL) or cable modem technologies [2]. There are already proposals for FiWi access mesh networks [3], [4].…”
