Abstract

Mobility models are used to represent the movement behavior of mobile devices in ad hoc networks simulations. As a consequence, the results obtained via simulations for specific characteristics related to mobile ad hoc networks are expected to be significantly dependent upon the choice of a particular mobility model under consideration. In this context, we present in this work a new mobility model, based on Birth-Death stochastic processes, which allows us to adjust mobility parameters according to the movement profile intended to be represented. The impact of mobility models in the simulation of ad hoc networks is observed through the performance evaluation of metrics related to the AODV routing protocol, by comparing the results obtained under the Birth-Death framework used in this paper with those calculated under the Generic Individual Mobility Markovian and the Random Waypoint models.
