Evaluation of mobility model is an important means to ensure the quality and design level. At present, many mobility models are proposed for opportunistic networks. But, there is no practical quantitative evaluation system to evaluate the mobility models. Firstly, this paper put forward a comprehensive evaluation index system of mobility model based on the analysis of the main factors affecting the quality of mobility model and the relationship between them. Secondly, based on the theory of fuzzy comprehensive evaluation, this paper put forward a fuzzy comprehensive evaluation model for mobility model (FCEM). In this model, the membership function of fuzzy mathematics is used to deal with the fuzzy evaluation of each index of the mobility model. The model realizes the quantitative evaluation of mobility model. This model not only provides new ideas and methods for mobility model evaluation, but also provides help and guarantee for mobile node modelling. Finally, the application of the model is demonstrated through the evaluation of the random waypoint (RWP) model.
