A quorum-based framework for establishing control channels in dynamic spectrum access networks
Establishing a control channel for medium access control is a challenging problem in multi-channel and dynamic spectrum access (DSA) networks. In the design of multi-channel MAC p...

Allocating dynamic time-spectrum blocks in cognitive radio networks
A number of studies have shown the abundance of unused spectrum in the TV bands. This is in stark contrast to the overcrowding of wireless devices in the ISM bands. A recent trend...
