The authors consider the problem of joint routing, scheduling and power control in a multihop wireless network when the nodes have multiple antennas. They focus on exploiting the multiple degrees-of-freedom available at each transmitter and receiver due to multiple antennas. Specifically, they use multiple antennas at each node to form multiple access and broadcast links in the network rather than just point to point links. They show that such a generic transmission model improves the system performance significantly. Since the complexity of the resulting optimization problem is very high, they also develop efficient suboptimal solutions for joint routing, scheduling and power control in this setup.
