“…To this aim [4] has proposed a joint optimization approach where allocations for converters and paths for routing are calculated simultaneously. Based on different parameters like number of channels, associated wavelength and required number of hopes between nodes performances of WDM have been discussed in [5].The benefits of converters in WDM have discussed in [6].To maximize the performance, it is necessary to allocate wavelength converters to the network nodes optimally. [ 7] has proposed a multiobjective optimization approach, based on a multi-objective evolutionary algorithm (MOEA), where the blocking probability and the number of wavelength converters are simultaneously minimizing.…”

In this work, optimal assignment of full range wavelength converters have done over available nodes in wavelength division multiplexing optical network to maximize the total utilization of deployed converters. This will increase the performance by cost ratio by keeping the deployed converters busy maximally. The optimization model has solved by heuristic method to search the solution space efficiently through self adaptive form of differential evolution. A mechanism has also proposed to handle the dynamic utilization under the same network through maintaining the diversity in the population by insertion of a new member in each generation.

In this paper, we have proposed a restricted shared protection scheme in wavelength convertible optical network. In our proposed approach, we have included both alternate path routing and partial placement of wavelength converter for reduction of blocking probability. With computer simulation, we have evaluated the performance of our proposed approach, by comparing it with the existing shared protection

“…For the improvement of blocking probability performance, the network requires the placement of wavelength converters. Wavelength convertible optical networks have been studied using various techniques: converter placement [13], converter allocation [14], conversion based router architectures [15] and sparse wavelength conversion [16]. Here, to reduce the number of wavelength converters for blocking performance improvement, we use optical placement of wavelength converter in limited number of nodes of the network.…”
