稀疏场景下基于网络编码和RSU数据传输的研究
RESEARCH ON DATA TRANSMISSION BASED ON NETWORK CODING AND RSU IN SPARSE SCENE
摘要
Abstract
The scene of data transmission in VANET mainly includes vehicle intensive urban road scenes and vehicle sparsely in remote areas.Nowadays, most of the research is focused on the data transmission in the vehicle intensive scene.In the sparse VANET, the probability of meeting between the nodes of the vehicle is limited, so the data transmission faces the challenges of large channel load, high transmission delay and low bandwidth utilization.In order to improve the transmission performance of the packet in the sparse scene, a transmission strategy RORLNC based on the inter-generation gradual network coding and RSU is proposed.Through the coding between the various code generation operation, can effectively prevent packet loss caused by the encoded data packet can''t be decoded.In addition, the best forwarding node can be found by RSU, which can avoid the long-term failure to forward the encoded data packet.The simulation experiment is carried out with NS-2 and MOVE software, and the experimental results show that RORLNC has higher throughput and lower average forwarding delay than the existing DDR algorithm.关键词
