Zhang Ruifang, Chen Yang, Liu Yangxue

ABSTRACT: Aiming at the problem that the weight of complex performance index is difficult to make decision in wireless network environment, put forward a weight evaluation method using entropy to determine the indicator weight and construct the weight evaluation model of entropy weight method to evaluate the performance index objectively. With smoothly increasing the node size of wireless workstations, OPNET network simulation software is adopted to record network performance data. After analysis, the entropy information can be used to feedback the contribution degree of performance index information objectively and accurately. The weight decision-making method based on entropy method make reflect the relative importance of network performance index objectively. Moreover, because of its strong adaptability and good flexibility, this method can be widely used in the evaluation of the importance of various network performance indicators.
