On Non-Stationary Urban Macrocell Channels in a Cooperative Downlink Beamforming Scenario
—A common simplification in the treatment of random linear channels is the assumption of stationarity of the channel in time. The wireless channel is, however, known to be inher...

A New Phase Transition for Local Delays in MANETs
: We study a slotted version of the Aloha Medium Access (MAC) protocol in a Mobile Ad-hoc Network (MANET). Our model features transmitters randomly located in the Euclidean plane, ...

Is ALOHA Causing Power Law Delays?
Abstract. Renewed interest in ALOHA-based Medium Access Control (MAC) protocols stems from their proposed applications to wireless ad hoc and sensor networks that require distribut...
