Abstract
In a vehicular network, all mobile nodes in communication are affected by Doppler Effect (DE) caused by the mobility of node. DE contributes considerably to the channel degradation in a Vehicular Ad-hoc Network (VANET). In this paper, a novel Modulation Code Scheme (MCS) adaptation technique to combat DE is presented. This method called Automatic Doppler Shift Adaptation (ADSA) is a new way of optimizing the transmission system medium based on extensive simulation. The performance evaluation of the ADSA method is explored and compared to the Binary Phase Shift Keying (BPSK) with rate 1/2. Some published works have shown that a higher DE can only be combated using BPSK rate 1/2. However, results from simulations clearly demonstrate that the ADSA method outperforms BPSK rate 1/2 MCS under various channel condition in terms of Bit Error Rate (BER), and data rate which results in improved throughput.
