The combination of emerging new communication technologies, economic growth, and current limitations on the amount of available dedicated spectrum necessitate sharing spectrum dynamically between incumbent (primary) users and opportunistic (secondary) users. This paper builds upon the seminal “spectrum jails” paradigm — a mathematical model for light-handed ex-post enforcement. Analyzing this as a...
The current approach to regulate spectrum sensing seems light-handed (just specify the target sensitivity), but has very heavy-handed consequences. The problem is that sensitivity is an intermediate metric that is convenient for certification, but is not reflecting the true externalities imposed by inadequate sensing. This mismatch causes overhead: usually an over investment in sensing at the single-radio...
