Abstract：Existing mobility models are usually applied in application scenarios such as pursuing,striking and rescuing,and simple linear motion is used,while there are certain defects in the research of curved mobility models for multi-obstacle scenarios in real scenarios.Based on this,this paper analyzes the demand of real application scenarios,uses the repulsive force method of re-pulsive force to avoid obstacles,and realizes the curved motion of nodes by transforming the speed of node motion into derivative vector according to the characteristics of Hermite curve,and proposes a movement model based on Hermite curve,which makes up for the defects of curved movement model for complex multi-obstacle scenarios.In order to study the performance of the model in ap-plication scenarios,the spatial probability distribution of the nodes of the model is investigated and compared with the classical SRMM and RWPM models.The experimental results show that the node motion under this model shows a uniform distribution,which can provide a more realistic application scenario for the simulation of Ad hoc networks.
