Abstract

The invention discloses a reliable communication method based on adaptive power control (APCRC) for a vehicle area network, belonging to the field of digital communication. In a traditional routing protocol, a vehicle adopts a fixed transmission range, but the vehicle density in a vehicular ad-hoc network changes rapidly due to high-speed movements of vehicles, the invention proposes an APCRC fora vehicle area network in order to select different transmission range and transmission power in different time. In the method provided by the invention, the communication time of vehicles-to-vehicles(V2V) communication links is calculated at road sections and road intersections according to directions of vehicle speeds, timers of neighboring nodes are set according to reliability of links of thenodes, geographical advancing distances, the sizes of contention windows, and so on, routing decisions are made, nodes having higher priorities have shorter waiting time, and the node having the highest priority among all neighboring nodes will send a data packet first to ensure the success rate of data packet delivery during V2V communication.

Description

technical field [0001] The present invention relates to the characteristics of VANET network and the problem of low delivery rate of data packets in routing protocol design, and in particular to a Reliable Communication Method Based on Adaptive Power Control (APCRC) applicable to urban scenes ), belonging to the field of digital communication. Background technique [0002] In recent years, with the rapid development of automobile industry technology, communication technology, computer technology and other fields, intelligent transportation system (Intelligent Transportation System, ITS) came into being. Vehicular Ad-Hoc Networks (VANETs) is a mobile ad-hoc network (Mobile Ad-HocNetworks, MANETs) in an application scenario, which is composed of vehicles equipped with communication transmission modules as nodes, centerless, self-organizing , Physical networks with frequent topology changes. In the vehicle-to-vehicle communication (Vehicles-to-Vehicles, V2V) of the vehicle ad...
