Power levels and packet lengths in random multiple access
This paper extends our earlier results. We assume that the receiver has the capability of capturing multiple packets so long as the signal-to-interference-plus-noise ratio (SINR) o...

Latency-sensitive power control for wireless ad-hoc networks
We investigate the impact of power control on latency in wireless ad-hoc networks. If transmission power is increased, interference increases, thus reducing network capacity. A no...
