In wireless networks for spectrum sharing among heterogeneous nodes, an issue of significant interest is the interference among coexisting systems, and understanding the essential quantities, such as interference distribution, is fundamental to the design of spatial spectrum sharing methods. This paper analyzes the performance of heterogeneously characterized nodes and investigates efficient spectrum...
Based on interference temperature model, the spectrum sharing problem between the secondary user and primary user can be formulated as optimization problem. In this paper, we propose a suboptimal distributed non-cooperative game theoretic power control algorithm for solving this optimization problem. Simulation results show that the proposed algorithm provides significant power saving compared to...
