Placement of ONUs and Wireless Routers in Fiber-Wireless Access Network with Survivability Constraints

Abstract:

Survivability is one of the key issues in Fiber-Wireless (FiWi) access network since a single network component failure may cause enormous data loss. This paper focuses on survivability of citywide FiWi access network and proposes a scheme using Integer Linear Programming (ILP) to tolerate the failures of distribution fiber and WiFi routers considering coverage problem. Simulation shows good performance of this scheme. When WiFi routers and ONUs are places in suitable potential sites, the maximal coverage of uses and survivability of FiWi access network are realized.
