The selection of as few as possible proper nodes for placement of regenerators (RPP) in translucent optical networks is an active area of research. In this paper, we propose a strategy for sparse placement of regenerators in translucent optical networks named as Computation of Locations of Regenerator nodes (CLR). We analyze the effectiveness of our approach for large WDM networks. Simulation results show that our scheme CLR produces remarkable better results in terms of number of sparsely placed regenerator nodes and blocking probability when compared with the existing heuristic. Scheme CLR is also able to provide a route between any source-destination pair and thus solve RRP (Routing with Regenerator Problem) while utilizing lesser number of channels (maximum value) in each optical fiber.
