—We consider opportunistic spectrum access (OSA) strategies for a transmitter in a multichannel wireless system, where a channel may or may not be available and the transmitter m...
— Physical carrier sense for wireless multihop networks has attracted a certain degree of attention since it is a simple yet important mechanism for distributed channel access. S...
We consider transmission using transmit and reception using receive antennas in a wireless environment assuming that neither the transmitter nor the receiver knows the channel coef...
—This paper aims at improving the power efficiency of the CSMA/CA protocol for transmission of multimedia information over multihop wireless channels. Using a distance dependent ...
—Recently, spectrum-agile (SA) networks have been recognized as a viable solution to the spectrum-scarcity problem in wireless communications. In SA networks, secondary (unlicens...
