Abstract

The use of multicasting over multi-hop networks seems an attractive new way to provide support to real-time applications like video streaming. In this paper, we proposed a 2-hop Dual Amplify-and-Forward (DAF) relay scheme. In this scheme, only the intermediate nodes (relay nodes) can cooperate with each other and there is no cooperation between transmitting and receiving nodes. This scheme has achieved a 4 dB gain over the earlier proposed 2-hop multicast based virtual MIMO relay scheme. In this paper we compare the two multicast relay schemes and analyze their performance with the help of MATLAB simulation.
