Abstract: For solving the inconsideration of power issues in current application deployment decision-making system, a more thoughtful system model is proposed by adding the power factor into the model. What’s more, a parameter-adjustable windowed mapping algorithm is designed to deal with the problem when the number of processors that composes the network in SDR platform is relatively high. The simulation reveals that by applying the proposed model, instead of current system model, total energy can be saved by nearly five percentages and with the proposed algorithm, the performances and complexity of algorithm can be balanced so that user-tolerable performances can be achieved and executing time can be saved by tuning the parameter.
