The wireless network communication mode represented by the Internet ofvehicles (IoV) has been widely used. However, due to the limitations oftraditional network architecture, resource scheduling in wireless networkenvironment is still facing great challenges. This paper focuses on theallocation of bandwidth resources in the virtual network environment. Thispaper proposes a bandwidth aware multi domain virtual network embeddingalgorithm (BA-VNE). The algorithm is mainly aimed at the problem that usersneed a lot of bandwidth in wireless communication mode, and solves the problemof bandwidth resource allocation from the perspective of virtual networkembedding (VNE). In order to improve the performance of the algorithm, weintroduce particle swarm optimization (PSO) algorithm to optimize theperformance of the algorithm. In order to verify the effectiveness of thealgorithm, we have carried out simulation experiments from link bandwidth,mapping cost and virtual network request (VNR) acceptance rate. The finalresults show that the proposed algorithm is better than other representativealgorithms in the above indicators.
