Efficient routing with optimal resources is one of the challenging tasks in the design of DWDM networks. Wavelength Converter (WC) is an important resource, as the placement of WCs affects the network performance and the quantity of WCs affects the cost of the network. With the help of WCs the network performance can be maximized by removing the wavelength continuity constraint. As WCs are very expensive, selecting the candidate nodes for the placement of WCs in a network is important. In this paper we have proposed an optimized approach for the placement of WCs in the presence of tunable transceivers (TTRs) and fixed transceivers (FTRs). The performance analysis has been carried out for above approaches. Observation shows that sparse partial wavelength converters with various loads requires only 2.4% converters. When tunable transceivers are used an average reduction of 73% in blocking probability and average saving of 91% in required number of converters.

Due to huge size of the data and quick transmission of data between the nodes present in the optical network, a condition of network traffic is created among the nodes of the network. This issue of traffic can be overcome by employing numerous traffic grooming techniques. In this research paper, the best suitable shortest path is determined by the multi objective modified PSO algorithm and an innovative visibility graph based Iterative Hungarian Traffic grooming algorithm is implemented to reduce the blocking ratio through improving the allocation of bandwidth between the users. Then finally the performance analysis is carried out by means of performance measures such as traffic throughput, transceivers count, average propagation delay, blocking ratio, and success ratio. It can be inferred that the proposed work obtains enhanced outcomes when compared to the other existing techniques.
