Cognitive optical wireless network

Abstract

Optical wireless network has the potential to serve both data centers and metropolitan area networks. Free space optical networks has one dimension that is not encountered in fiber networks and that is its ability to reconfigure its connection topology by beam steering in time scale of at least mS if not µS. This paper describes a cognitive technique for the fast estimation of traffic changes and triggering network connectivity reconfigurations to achieve congestion control and load balancing. Significant performance gains are expected.
