MultiPoint Relays (MPR) selection is a good step toward building a very proficient routing scheme for multicast/broadcast communications. It considers the fact that data transmitted by a node is overheard by all the users in the sender's communication range, called the Wireless Broadcast Advantage (WBA). However, when a node elects its MPR nodes it does not consider their channel qualities (i.e. they do not consider the Multi-User Diversity (MUD) factor), that has a significant influence on the network performance. Many other works consider the MUD and the Rate Adaptation (RA) features.
