Selection of Optimal Relay Nodes for Vehicle Networking Based on Wireless Sensor Network
摘要
Abstract
In order to meet the communication requirements of high speed,low delay and high reliability under the random distribution of the vehicle-to-everything,an optimal relay node selection method for the vehicle-to-everything under the wireless sensor network is de-signed.D2D communication technology is adopted and clustering factors are introduced to achieve clustering of vehicles traveling within the communication range.Based on the physical transmission distance and social relationship strength of each node vehicle within the communication range,a secondary selection of relay nodes is conducted within each cluster to establish a candidate set of relay nodes.By considering the node transmission efficiency,transmission delay and packet loss rate,the optimal relay node judgment matrix is con-structed.The element product algorithm is introduced to solve the judgment matrix and complete the selection of the optimal relay node in the vehicle-to-everything.The results show that the relay node selected by the proposed method has a data transmission throughput of 9.1×105 bps,interruption probability of 6.8×10-5,and the maximum energy efficiency value can reach 12.8 bit/J,which indicates that the proposed method can ensure the efficient and stable transmission of data in the vehicle-to-everything,and is of great significance to the development of intelligent transportation field.关键词
