Paper Abstract:
|
This work gives emphasis to implement five strategies for a parallel hybrid metaheuristic for configuration of a service used in the video distribution. In particular, we study the video distribution service called DynaVideo, on the digital network. This service uses mobile replication to adjust its configuration to demand variations, characterized by its clients number and placing. This problem can be formulated as Steiner Tree Problem. In following, we describe some computational experiments compared with the literature. The results indicate the strategies discussed were effective in reduction the processing time and improved results compared to sequential metaheuristic. |
