Research of Representative Group Mobility Models
Hou Yan-shu · 2014
Mobility models are the base of mobility modeling and simulation.Individual mobility models have been studied thoroughly and some defects,such as imperfect nodes distribution and velocity attenuation,have been proved.By comparison,less researches have been made on group mobility models.This paper researched 2 most representative group mobility models,i.e.RPGM and ECM,analyzed their nodes distribution,velocity distribution,time correlation,nodes' correlation and parameters' controllability,provided reference for model choice and parameter setting.
