Abstract:

To evaluate the transmission capacity of vehicular Ad-hoc networks (VANETs) wireless link, a link transmission performance evaluation model used for vehicle mobility and data transmission character is proposed. VANETs link transmission capacity metric is built based on link residual lifetime distribution and data transmission service time distribution obtained by Monte Carlo simulation and data fitting. The evaluation model is applied in VANETs simulation to assess the transmission performance of paths selected byad hoc on demand distance vector (AODV) protocol or prediction based on routing (PBR) protocol. Simulation is carried out on TrueTime tool box of Matlab/Simlink and is shown that the link transmission performance evaluation model is able to assess link transmission capacity effectively for both route protocols and different node speed scenes in data transfer service.

Key words: vehicle Ad hoc networks, link transmission performance, vehicle mobility mode, data transmission service
