Several mobility models attempt to simulate the group mobility model in ad-hoc network simulation. However, most have certain limitations that prevent the model to be an accurate real world representation. There are limitations that a mobility model does not address such as environmental changes that occur that will alter the behavior of mobile nodes (MNs). Also, there are simulation limitations that allow the MNs to overlap or collide which is also more so an unrealistic characteristic. We propose the implementation of a Group Force Mobility Model to address these limitations in an effort to create a more realistic representation of MN behavior in an environment. In addition, to show the simulation results, we also conduct a comparative performance study of our approach with the Reference Point Group Mobility Model.
