Performance Analysis of Multi-Source Multi-Destination Cooperative Vehicular Networks with the Hybrid Decode-Amplify-Forward Cooperative Relaying Protocol

This paper provides symbol-error-rate (SER) performance analysis and minimum power allocation for multi-source multi-destination cooperative vehicular networks using the hybrid decode-amplify-forward (HDAF) cooperative relaying protocol. Previous studies of power allocation minimize the outage probability subject to a total power constraint. Our approach aims to minimize the power allocation in order to maintain the SER below a specific threshold and thus it achieves lower power consumption. Numerical tests show that HDAF has significantly reduced SER compared with the forward strategies of amplify-and-forward (AF) and decode-and-forward (DF). Furthermore, the power consumption in our proposed approach is much less than that in AF and DF.
