| 摘 要： | 现有基于RWM移动模型的自组织网络路由协议仿真经常会引起一些问题,如平均运动速率衰减、移动节点分布不均匀等,使得路由协议的仿真不准确.针对这些问题,本文应用掌形积分对RWM移动模型的初始化重新进行了设计,该设计方法简单、易于实现.在此基础上,作者仿真了自组织网络常用的路由协议并进行性能分析.仿真结果表明,在RWM移动模型和修改后RWM移动模型下的路由协议性能存在差别.RWM移动模型的平稳性会对路由协议性能产生显著的影响.

| Abstract: | The existing simulation of Ad hoc routing protocols based on RWM often causes subtle problems such as the attenuation of average speed,the non-uniformity of mobile nodes' distribution,which make it inaccurate to simulate the routing protocols.In this paper,we apply the Palm Calculus to the RWM and propose a simple method to reconstruct the initialization of RWM.We also simulate the normal Ad hoc routing protocols and analyze their performance based on Palm Calculus.The results indicate that there are routing protocol performance differences between the modified RWM and RWM.The stability of RWM has a significant impact on the performance of Ad hoc routing protocols. |
