摘要：Due to the high mobility and limited transmission range of vehicles, the data download capacity of single vehicle is greatly limited, which brings poor performance to users. In this paper, we divide the data into blocks. We want to design a data block broadcasting scheme so that all vehicles can receive data blocks as many as possible in a base station(BS) range. We first give the mathematical model and find it is difficult to be solved directly. Then we design a heuristic algorithm for solving the problem. The main idea of our algorithm is to give each data block a weight. The data block with the largest weight is broadcast by BS, and several vehicles are selected to broadcast the remaining data blocks. We call our algorithm as the Iterative Strategy for Data Allocation(ISDA) algorithm. Then considering the actual situation, we subsequently propose the online algorithm. Through experiments and simulations, we prove that our scheme can effectively improve the data download rate and reduce the download delay.
