Abstract

The fading environment plays a critical role for vehicular communication. High fading environments lead to high data losses, which seriously affect the communication of safety applications in vehicular ad-hoc networkings (VANETs). Rician and Rayleigh fading models are considered to be realistic fading models for vehicular communication. This paper contributes in two aspects specifically for safety applications (a) Evaluation of Rician and Rayleigh fading for vehicular environment (b) It proposes a suitable combination of data rate and transmission power (Tx) that will minimize fading effects caused by Rician and Rayleigh fading. NCTUns is used to simulate vehicles with a safety application protocol called wave short message protocol (WSMP). By using appropriate combination of these parameters, significant improvements have been observed in throughput.
