Abstract :
In this paper we study two basic properties, capacity and connectivity, of Cognitive Radio networks. Our goal is to quantitatively characterize the relationship and tradeoff among key system parameters involved in these properties, incorporating channel randomness and interference into the performance analysis. In particular, we explore the characterization of a capacity metric, single-hop transport capacity, with respect to arbitrarily and randomly located receivers, and investigate a fundamental connectivity metric, node isolation probability. The tradeoff between capacity and connectivity is also revealed.
