Efficient data packet transmission algorithm for IPV6 mobile vehicle network based on fast switching model with time difference

In the IPV6 wireless network, the nodes are numerous, mobile. and have high latency. In this work, we propose an efficient data packet transmission algorithm based on fast switching model with time difference called EDPTA. A mathematical communication model is proposed in the high-speed IPV6 vehicle network. This model considers the probabilistic relationship between data transmission in different time intervals and the ratio of newly added neighboring and current nodes. On this basis, a data packet transmission algorithm for dynamical vehicle nodes is designed. Communication threshold is used to control the communication times of vehicle nodes. Experiments show that the proposed algorithm has good performance in terms of lifetime, power overhead, and data reliability within the valid communication range compared with other algorithms.
