Opportunistic channel access scheme for cognitive radio system based on residual white space distribution
We propose an opportunistic channel access scheme for cognitive radio-enabled secondary networks. In our work, we model the channel occupancy due to Primary User (PU) activity as a...

Distributed Estimation over Wireless Sensor Networks with Packet Losses
A distributed adaptive algorithm to estimate a time-varying signal, measured by a wireless sensor network, is designed and analyzed. The presence of measurement noises and of packe...

Noncooperative power control and transmission scheduling in wireless collision channels
We consider a wireless collision channel, shared by a finite number of mobile users who transmit to a common base station using a random access protocol. Mobiles are selfoptimizin...
