Abstract
Objective:
Optical networks exploit the Wavelength Division Multiplexing (WDM) to meet
the ever-growing bandwidth demands of upcoming communication applications. This is achieved by dividing
the enormous transmission bandwidth of fiber into smaller communication channels. The major
problem with WDM network design is to find an optimal path between two end users and allocate an
available wavelength to the chosen path for the successful data transmission.
Methods:
This communication over a WDM network is carried out through lightpaths. The merging of all
these lightpaths in an optical network generates a virtual topology which is suitable for the optimal network
design to meet the increasing traffic demands. But, this virtual topology design is an NP-hard problem.
This paper aims to explore Mixed Integer Linear Programming (MILP) framework to solve this design
issue.
Results:
The comparative results of the proposed and existing mathematical models show that the
proposed algorithm outperforms with the various performance parameters.
Conclusion:
Finally, it is concluded that network congestion is reduced marginally in the overall performance
of the network.
