Abstract:

5G based vehicle networks face with the requirements of high data rate, low latency, high reliability and mas-sive multimedia streaming distribution. A LTE D2D was proposed based vehicle networks communication architecture and then a movement consistency based vehicle clustering algorithm was designed. The results show it increases sus-tained D2D communication time and improves the reliability of D2D communication. Besides, a D2D cooperative relay-ing forward strategy under the constraint of latency for distributing multimedia streaming were proposed, which resulted in significant improvement of data transmission rate and network throughput.
