Abstract

In this paper, we propose an edge caching scheme in vehicular networks, which allows multiple roadside units (RSUs) to collaboratively cache part of content in a distributed way and delivery coded packets by using fountain codes. The overlapping placement algorithm is proposed to increase the correlation of data packets cached in RSUs. When distributing content, the unequal probability selection algorithm of generating fountain codes is proposed to decrease the decoding overhead. The simulation results prove the scheme above that the transmission efficiency and the successful content acquisition rate can be improved than the traditional coded caching when the caching memory is limited.
