Scheduling in a broadcast channel based on partial channel-state-information at the transmitter is carried out in an opportunistic way. In this paper, the number of generated beams...
We address the message authentication problem in two seemingly different communication models. In the first model, the sender and receiver are connected by an insecure channel and...
As many radio chips used in today's sensor mote hardware can work at different frequencies, several multi-channel communication protocols have recently been proposed to improv...
— We consider a collocated wireless network where all links contend for a given channel and each link can hear others’ transmissions. Due to channel fading, the link condition ...
—Multiuser diversity scheduling is studied in a single cell system with a limited scatterers channel. The scheduler implements the proportional fairness algorithm with infinite ...
