Joint Network Capacity Region for Cognitive Networks Heterogeneous Environments and RF-Environment Awareness

In this paper, the authors characterize the joint network capacity region for a licensed broadcast (primary) and ad hoc cognitive (secondary) network in a heterogeneous environment, including indoor and outdoor transmissions, under various spectrum (white space) detection techniques. Each technique delivers a different degree of RF-environment awareness - the more a device knows about its environment the larger the network capacity region. To quantify the gains, they develop a simple stochastic model capturing the interdependency amongst primary and secondary nodes and compare their joint capacity.
