1. What have the authors contributed in "Spatial interference mitigation for multiple input multiple output ad hoc networks: miso gains" ?
The authors consider spatial interference mitigation at the transmitter for multiple input single output ad hoc networks.. The authors apply zero forcing beamforming at the transmitter, and analyze the corresponding network throughput and transmission capacity.. The authors derive scaling laws for the transmission capacity and show that for a large number of antennas, the maximum density of concurrently transmitting nodes scales linearly with the number of antennas at the transmitter, for a given outage constraint.

2. What have the authors stated for future works in "Spatial interference mitigation for multiple input multiple output ad hoc networks: miso gains" ?
Future work includes devising a distributed multiple input multiple output interference mitigation strategy, where in addition to interference nulling at the transmitter, antennas at the receiver are used to cancel residual interference.
