Abstract

Hierarchical cooperation schemes in wireless networks rely on local cooperation among neighboring nodes to create virtual multiple-input multiple-output (MIMO) connections between clusters of nodes. It was shown that, by applying the virtual MIMO technique recursively in a hierarchical manner, the sum rate of all source-destination pairs can scale linearly with the number of nodes in the network. In this paper we focus on the impact of local cooperation and establish new capacity scaling bounds for the virtual MIMO transmission taking into account the constraints of local communication both at the transmitters and the receivers. We show that the cost of local communication, which is inevitable to establish the virtual MIMO transmission, grows exponentially with the number of layers in the cooperation hierarchy and plays a vital role in determining the overall performance of the hierarchical virtual MIMO cooperation.
