[In this chapter, we consider the problem of opportunistic spectrum access in a kind of networks, where the users are spatially located and direct interaction/interference only emerges between neighboring users Y.

Zheng, B. Zhao, Mob. Netw. App. (11(4):555–576, 2006), [1–6]. We investigate this problem from a perspective of interference minimization. Note that the commonly used interference model in the literature is the PHY-layer interference models, in which the focus is to minimize the amount of experienced interference C. Lacatus, D. Popescu, IEEE J. Sel. Topics Signal Process (1(1):189–202, 2007), [7]. In methodology, the PHY-layer interference model is more suitable for wireless communication systems with interference channel models, e.g., the code-division multiple access (CDMA) and orthogonal frequency-division multiple access (OFDMA) systems.]
