Since the landmark work by Gupta and Kumar on the capacity of wireless ad hoc networks, considerable attention has been devoted to improving or analyzing their results. Ozgur et al. demonstrated that the capacity of random wireless ad hoc network scales linearly with n by allowing nodes to cooperate intelligently using distributed Multiple-Input Multiple-Output (MIMO) communications. Unfortunately, distributed MIMO techniques require significant cooperation and feedback information among nodes to achieve capacity gains using multiple antenna systems. These challenges include synchronization during transmission and cooperation for decoding which makes distributed MIMO systems less practical.
