A Distributed Virtual MIMO Coalition Formation Framework for Energy Efficient Wireless Networks
In this paper, the authors consider a distributed virtual Multiple-Input Multiple-Output (MIMO) coalition formation algorithm. Energy savings are obtained in the reverse link by forming multi-antenna virtual arrays for information transmission. Virtual arrays are formed by finding a stable match between two sets of single antenna devices such as Mobile Stations (MSs) and Relay Stations (RSs) based on a game theoretic approach derived from the concept of the college admissions problem. Thus, power savings are obtained through multi-antenna arrays by implementing the concepts of spatial diversity and spatial multiplexing for reverse link transmission.
