群组移动模型是无线网络研究中的基础问题之一。移动模型对无线网络协议的设计、算法的性能评价等问题的研究具有重要意义。回顾了现有群组移动模型的特点和应用范围,它们都不能有效模拟无线有组织网群组行为特性。在分析无线有组织网群组特点的基础之上,提出了以中心节点为参考点的无线有组织网群组移动模型,模型仿真更加接近真实无线有组织网络。通过设置不同参数对网络仿真与网络实际情况进行分析比较,证实了新的群组移动模型的可用性。
Group mobility model is one of the basic research issues for designing network protocol and evaluating algorithms performance in wireless network.This paper reviewed the characteristics and applications of the group mobility models which can't effectively simulate behavior of the wireless organization networks(WON).Based on the analysis of characteristics of WON,it proposed the central node as reference point of WON group mobility model(CWONM).By setting different parameters to compare the actual network and simulation networks,it confirmed that the new group mobility model is available.
