Opis

Free space optical (FSO) communication provides functionalities that are different from fiber optic networks and omnidirectional RF wireless communications in that FSO is optical wireless (no infrastructure installation cost involving fibers) and is highly directional (no frequency interference). Moreover, its high-speed data transmission capability is an attractive solution to the first or last mile problem to bridge to current fiber optic network. In order to be useful, FSO communication must deal with the following fundamental problems: (1) How to quickly and precisely establish and maintain optical links between nodes in the network? (Pointing, Tracking, and Acquisition); (2) How to optimize net­work performance in terms of network cost and congestion? (Topology Optimization); (3) How to respond autonomously to possible network performance degradation due to link loss or sudden changes in traffic demands? (Topology Control). This book, therefore, provides solutions to the above problems with both a hardware approach for developing self-organized pointing and a software approach for developing accurate heuristic algorithms for topology optimization in bi-connected FSO networks.
