On the Interactions between Mobility Models and Metrics in Mobile ad hoc Networks
Elmano Ramalho Cavalcanti, Marco Aurélio Spohn · International Journal of Networks and Communications · 2013
In this paper we investigate several gaps on the study of mobility models in Mobile ad hoc Networks (MANETs). We present a survey of taxono mies for mob ility models, and introduce a novel taxono my for mob ility met rics, which is then employed for classifying the surveyed metrics. It is performed a co mprehensive experimental study taking into account an heterogeneous set of mobility models and seven representative mobility metrics. As a first result, we show how effective metrics are on distinguishing among models. Additionally, our simu lation findings reveal that, independently of the movement pattern of mobile nodes, there are similar relat ionships among node speed and several mobility met rics. Furthermore, we estimate the impact of each mobility model parameter on the evaluated mobility met rics, revealing the variables that most impact the metrics. Lastly, through stepwise mu ltip le linear regression analysis we created accurate models fo r predict ing the value of link duration, node degree and network part itioning met rics fro m a proposed set of novel predictors. The results presented in this work provide significant insights on the comprehension of mobility models and metrics and the interactions between them in MANETs .
