Distributed Scheduling Algorithm for Cooperative Transmission With Multiple Relays
Cooperative transmission can improve the performance of wireless ad-hoc systems due to its spatial multiplexing gain. Given that multiple cooperative relays which belong to the same source-destination pair can transmit simultaneously in the cooperative transmission, it is different from normal data transmission in which only one source node transmits in a single source-destination pair. Therefore, a new distributed scheduling algorithm for wireless ad-hoc systems should be devised. To this end, the authors propose a distributed scheduling algorithm for wireless ad-hoc systems with cooperative transmission in which multiple cooperative relays can transmit at the same time by using Amplify-and-Forward or Decode-and-Forward scheme.
