Summary: 
A new load balanced channel sharing method (CSM), namely Heuristic Traffic Load Balanced (HTLB) CSM, is proposed for metro-wavelength division multiple access (WDMA) networks. In particular, HTLB CSM is designed to be effective for pre-allocation based medium access control (MAC) protocols by balancing traffic loads corresponding to pre-assigned destinations per time slot. As a result, HTLB CSM is shown to provide lower time complexity than the well-known sub-optimal load balanced CSM, MULTIFIT CSM. Furthermore, the Jain Index of the HTLB CSM is shown to be higher and more consistent than the MULTIFIT CSM and other pre-fixed CSMs under diverse traffic conditions.
