Abstract:

Message congestion control in vehicular ad hoc networks is a major issue and several algorithms have been proposed in literature. The linear adaptive approach is represented by the linear message rate integrated control (LIMERIC) algorithm, which integrates the error in order for the message generation rate to converge to a desired value. The stability of this algorithm has been established in the case of repetitive transmission of the basic safety messages in a single-hop communication setting. However, the communication might be realized in a multi-hop fashion, so, in this work we adopt simple models of single and multiple lane roads to investigate the stability of the LIMERIC algorithm in a multi-hop communication setting. Our results indicate that the stability of the system depends on the vehicle density, which dictates appropriate choice of the algorithm parameters for each vehicle density to avoid instability. To this end, we propose the use of certainty equivalent controllers, which adapt the parameters based on vehicle density estimates. Inspired by recent works on adaptive probabilistic flooding, we propose that these density estimates are obtained using speed measurements via a nonlinear relationship of the traffic flow equations whose parameters can be tuned using on-line parameter identification techniques.
