Abstract :
Uneven traffics may too much concentrate on specific nodes and the path requests will be blocked at these nodes in wavelength division multiplexing (WDM). This paper proposes a new load-balancing method applying link-cost adjustment based on betweenness centrality in WDM networks with wavelength converters. It is clarified that the proposed method drastically reduces a blocking probability as compared with that of the existing OSPF.
