A Novel Queue Priority Algorithm for Real-time Message in VANETs

摘要：

Without any doubt the research of VANETs plays an important role in ITS. This paper focuses on reducing the end-to-end delay and the packet loss ratio of the real-time message in VANETs. In this paper, a novel real-time message data packet queue priority algorithm which takes full advantage of the parameters(such as the relative distance, the relative velocity, the relative driving direction between the current packet forwarding node and the next hop node) of the VANETs and the real-time messages internal parameter(real-time message packet timestamp left from the deadline) is proposed. In the end, the performance of the algorithm in the two-lane highway scenario is simulated, the results show that this algorithm decreases the average end-to-end packet delay and the packet loss ratio compared to the FIFO queue scheme.
