Although establishing cooperation in a wireless network is a dynamic process, most game theoretic coalition formation models proposed in the literature are static. We analyze a dynamic coalition formation game based on a Markovian model for the spectrum sharing problem in an interference channel. Our model is dynamic in the sense that distributed transmitter/receiver pairs, with partial channel knowledge,...
Cooperative spectrum sensing for cognitive radio (CR) networks has been widely studied to increase the reliability of the primary user detection. However, when there are a large number of cooperating CRs, this typically leads to an increase in overhead in sensing reporting as well as in sensing report combining. A large number of CRs participating in cooperative spectrum sensing also increases the...
Iterative backward and forward consecutive mean excision (CME/FCME) algorithms are efficient in suppressing and detecting narrowband signals. Being computationally relatively simple, they can be applied for spectrum sensing in cognitive radios. In this paper, theoretical limits of detection for the CME algorithms are derived. These limits predict whether a signal is detectable or not. More specifically,...
