Performance Modeling of SEAD Protocol in Vehicular Environment

Abstract : Toward the growing number of the transport safety applications offered by VANET, a large amount of messages need to be efficiently disseminated between connected vehicles. The requirement for an efficient data dissemination in vehicular environment is ensuring the highest data reachability, using the minimum network resources within a short end to end delay. To meet these properties, researchers have addressed the data dissemination challenges, mainly the famous broadcast storm, which has lead to a wide variety of solutions. In this work, we present two Simple and Efficient Adaptive data Dissemination protocols called SEAD1 and SEAD2 that combine a probabilis-tic and a delay based approach. The originality of these protocols is that they can be adaptively tuned according to the VANET applications' requirements. Therefore, a rigorous performance evaluation of the protocols is proposed through an analytic model and a large set of NS3 simulations. The analytic results show excellent fits to the simulation results which confirm the accuracy of the proposed model. Moreover , based on our analytic model we became able to thoroughly study the protocols parameters' behavior and derive an accurate configuration. Thereby, a proper trade-off between the packet delivery ratio and the redundancy ratio is possible in attempt to tune the protocols performance according to the application criticality level.
