We develop a P2MP energy-saving routing design using Prim's algorithm to reduce the energy consumption of the transport network for multipoint services. By computer simulation, it is shown the developed algorithm provides an energy-saving topology within 1 second and reduces number of links up to 57% in 40 node network.
This paper describes a case study on a general-purpose Constraint Relaxation Problem solver, COASTOOL. Using COASTOOL,~ problem can be solved merely by declaring " what is the problem , " without programming " how to solve it. " The problem is solved by a novel method that generates a high-quality initial assignment using arc-consistency, and refines it… (More)
