On the Stability of Ad Hoc Group Mobility Models

Group mobility has been modeled for simulators to evaluate protocols in wireless ad hoc networks. These mobility models have to be verified in terms of their instant and long-run behaviors. This paper discusses importance and challenges of the stability evaluation for ad hoc group mobility models; proposes analytical technique for the stability of group mobility model and evaluation of the same via simulation. As a case study, we evaluate the personal network group mobility model (PNMM). The evaluation method presented in this paper can be applied to all generic ad hoc group mobility models in terms of stability analysis and simulations.
