Evaluation performance of the adaptive cell scheme in road to vehicle communications

This paper describes an adaptive cell scheme (ACS) in road to vehicle communications. This scheme reduces the frequency of a handover caused by movement between communication cells with adapting the size of the sub-domain adapted to vehicles' density. However, the traffic load increases when the size of the sub-domain is enlarged. Therefore, vehicles' density parameters to use varying the size of the sub-domain are discussed. Consequently, effectiveness of the ACS is evaluated by simulation.
