While a single fiber strand in wavelength division multiplexing (WDM) has
over a terabit-per-second bandwidth and a wavelength channel has over a
gigabit-per-second transmission speed, the network may still be required to
support traffic requests at rates that are lower than the full wavelength capacity.
To avoid assigning an entire lightpath to a small request, many researchers
have looked at adding traffic grooming to the routing and wavelength
assignment (RWA) problem. In this work, we consider the RWA problem with
traffic grooming (GRWA) for mesh networks under static and dynamic...
