Traffic Grooming in Hybrid Optical-Wireless Mesh Networks Using Knapsack Based Light Trail Approach

Passive Optical Network (PON) is an optical based network architecture, which can offers higher data rates than the conventional copper based access networks. On the other hand, it is often observed that bandwidth requirements increasing rapidly day by day. To beat this issue, it is needed to increases the bandwidth of PON by deploying the Wavelength Division Multiplexing (WDM) so that, multiple wavelength can be supported in upstream and downstream direction such PON are termed as Wavelength Division Multiplexed Passive Optical Network (WDM-PON). We proposed the static traffic grooming algorithm, to minimize the bandwidth blocking probability of the hybrid optical-wireless networks, using light trail approach. The proposed algorithm is simulated the with the hybrid network and compared the performance with existing algorithm. The simulation results demonstrate that the proposed algorithm performance superior than existing algorithm in terms of bandwidth blocking probability.
