A Random Group Mobility Model for Mobile Networks

In this paper, we investigate mobility model in mobile networking and propose a novel random group mobility model for mobile ad hoc networks. The presented model named charge vector group mobility model regards mobile nodes as particles carrying different kinds of charges. Reference points are also defined carrying only one kind of charge and moving in simulation area with some general rules. Mobile nodes then move according to several rules and transit among three states. This random group mobility model can illustrate the mobilities in real life, including aggregating, disaggregating, group movement and individual movement and show both randomness and some orderliness.
