Modelos Markovianos de Mobilidade Individual para Redes Móveis Ad Hoc

Carlos Alberto V. CamposLuis Felipe M. de Moraes

Mobility Models try to represent the movement behavior of mobile devices in Mobile Ad hoc Networks. These models are used in performance evaluation of applications and communication systems and, this way, they allow the analysis of the mobility impact. In this context, it is proposed in this paper Individual Mobility Models for Mobile Ad hoc Networks. These models were based in [1] and intend to represent a wider movement ability of devices. Using the proposed models is possible to move in the same direction, in adjacent directions, to accelerate and to stop, besides avoiding sharp turns and sudden stops. This way, it is tried a representation closer to the real movement of the users in an urban enviroment and in roads. In the paper, the models are described analytically by Markov Chains and are presented comparisons, by using simulation, between the Proposed Models, the Waypoint Model and the Random Walk Markovian Model.
