Performance Evaluation of Survivable Fiber-Wireless (FiWi) Access Network

摘要

FiWi support high speed transmission rate, hence any kind of failure may result in huge data loss. To prevent this, there is a requirement to design more survivable and reliable network. In FiWi networks there are two types of failures viz. ONU level failure and segment/OLT level failure. In the present work, to handle segment level failure, we propose an efficient algorithm viz. "Fully Mesh based protection scheme". In the proposed algorithm we connect backup ONUs from each segment in a fully mesh fashion. Simulation result shows that proposed algorithm improves network survivability in terms of reduced blocking probability.
