On the Asymptotic Capacity of Multi-Hop MIMO Ad Hoc Networks
Multi-Input Multi-Output (MIMO) is a key technology to increase the capacity of wireless networks. Although there has been extensive work on MIMO at the physical and link layers, there is limited work on MIMO at the network layer (i.e., multi-hop MIMO network), particularly results on capacity scaling laws. In this paper, the authors investigate capacity scaling laws for MIMO ad hoc networks. The goal is to find the achievable throughput of each node as the number of nodes in the network increases. The authors employ a MIMO network model that captures spatial multiplexing and interference cancellation.
