Novel Strategies for Sparse Regenerator Placement and Allocation in Translucent Optical Networks

In this paper we propose one allocation strategy and two strategies for sparse regenerator placement in translucent optical networks, namely Most Used Regenerator Placement (MURP) and Most Simultaneous Used Regenerator Placement (MSURP). The novel regenerators placement algorithms are compared with other ones presented in literature. They are tested on the proposed regenerator allocation algorithm. We investigate the behavior of the these algorithms under different load values and numbers of translucent nodes. The MU-RP obtained good results in relation to the algorithms presented in literature and the MSURP showed the best results in all cases.
