The problem of traffic grooming in gridded WDM is studied. First, the problem is expressed as an integer linear programming problem (ILP). The objective of optimization is to minimize the number of transceivers used in the network. Because of the computational complexity of the problem A heuristic algorithm is proposed to solve this problem. The numerical results show that this algorithm can get the same result as the optimal solution obtained by integer linear programming (ILP). In the WDM network, proper traffic grooming can be used Reduce the number of transceivers used in the network.
