A Markovian Model Representation of Individual Mobility Scenarios in Ad Hoc Networks and Its Evaluation

Abstract

Adequate representation of mobility is a very important issue in simulation of mobile ad hoc networks. In this context, we consider the characterization of the mobile nodes movement through a Markovian modeling. Our proposed representation allows for smooth movements and the generation of several different mobility profiles. This approach is also shown to be more suitable for use in various ad hoc networks scenarios than other proposed mobility models, such as the random waypoint (RWP) model. An evaluation of the proposed model is provided, under different border rule scenarios. In addition, the performance of AODV, DSR, and DSDV routing protocols is also studied through simulations, utilizing the proposed model, and the results obtained are discussed.
