Relayed transmission is an interesting topic in cooperative diversity. Some researchers propose power allocation schemes for relayed transmission by only considering transmission through a fixed relay node. In the authors' paper, they analyze a relayed transmission through a mobile relay node. They build up a transmission system model and determine the long term distribution characteristics of the movement of the mobile node. They also calculate the time-varying data rate for transmission through the mobile relay node and demonstrate the improvements due to mobility. Moreover, they illustrate the optimal power allocation for relayed transmission through the mobile relay node.
