针对容迟与容断网络路由协议评估中指标信息的灰色性问题,提出一种容迟与容断网络路由协议的综合评估模型。该模型采用层次分析法确定评估指标的权重,利用灰色理论建立评估样本矩阵与评估灰类,获得灰色评估系数与权矩阵,将评估路由协议性能的主观因素限制在很小的范围内,使评估结果更加客观可信。实验结果表明该模型是有效的。
Aiming at the grayness issue of evaluation metrics for performance evaluation of routing protocols in Delay and Disruption Tolerant Networks(DTN),this paper proposes a comprehensive evaluation model for routing protocols in DTN.It uses Analytic Hierarchy Process(AHP) to determine the weighting coefficients of evaluation indexes,applies the method of grey theory to construct the evaluation sample matrix and grey ranking to gain the coefficients of the grey evaluation and the weighting matrix.Based on the model,the subjective factors that influence the performance evaluation are restricted greatly and the objectivity of performance evaluation results is improved.Experimental results show that the model is effective.
