摘要

本文介绍了一种道路与车辆通信中的自适应小区方案。该方案通过调整与车辆密度相适应的子域的大小，减少了通信单元之间移动引起的切换频率。但随着子域规模的增大，流量负荷也随之增大。因此，讨论了车辆密度参数对子域大小的影响。最后，通过仿真对ACS的有效性进行了评价。

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.
