Lower bounds on the success probability for ad hoc networks with local FDMA scheduling
—This paper studies the performance of ad hoc networks with local FDMA scheduling using stochastic point processes. In such networks, the Poisson assumption is not justified due...

Ergodic spatial throughput of wireless ad hoc networks with Markovian fading channels
—Most work on wireless network throughput ignore the temporal correlation inherent to wireless channels, due to trouble with tractability. In order to better capture the temporal...
