OFDM transmission over a noisy fading channel for assessing a complete transmission acknowledgement scheme for VANETs

Abstract

Various computer simulations are used to illustrate the performance of a particular protocol. However, the number of parameters and logical layers considered is the key to getting accurate results. We extend our previous work of Complete Transmission Acknowledgement Scheme (CTAS) by running the proposed model on top of the physical layer. Effect of noise and the standard Orthogonal Frequency Division Multiplexing (OFDM) scheme is implemented in the physical layer and analysed. The physical layer performance evaluation parameters such as Bit Error Rate (BER) and Signal to Noise Ratio (SNR) are selected and the results show that the proposed protocol outperforms other contemporary acknowledgement schemes.
