Many mobility models attempt to provide realistic simulation to many real world scenarios. However, existing mobility models, such as RPGM  and others, fail to address many aspects. These limitations range from MN collision avoidance, obstacle avoidance, and the interaction of MNs within a group. Our research, the Group Force Mobility Model (GFMM)  proposes a novel idea which introduces the concept of attraction and repulsion forces to address many of these limitations.  describes some of the limitations and drawbacks that many models neglect This model effectively simulates the interaction of MNs within a group, the interaction of groups to one another, the coherency of a group, ad the avoidance of collision with groups, nodes, and obstacles. This paper provides a survey analysis of obstacle mobility models which are geometric- and non-geometric based and those which are geographic constrained and non-geographic constrained. In addition, we illustrates the GFMM's ability to avoid collision with obstacles, which is a vital property to posses in order to provide a realistic simulation. We compare our model with the commonly used RPGM model and provide statistical assessments based on connectivity metrics such as link changed, link duration, and relative speed. All will be detailed and explained in the paper.
