A Markov Chain Model for Evaluating Performance of Store-Carry-Forward Procedure in VANETs

摘要

The idea of Store-Carry-Forward has been introduced for using in sparse Vehicular Ad-Hoc Networks (VANETs) in order to answer the problems of VANET as a highly mobile partitioned ad-hoc network; however, there has not been a deep analytical discussion on performance of Store-Carry-Forward in different situations of vehicular network. In this paper, a Markov chain model for urban mobility is proposed. Based on the model, we analyze the procedure in a realistic urban scenario. It will be discussed why Store-Carry-Forward procedure is useful. Simulation results confirm the validity of our analytic approach.
