Abstract: Spectrum trading creates more accessing opportunities for secondary users (SUs), and economically benefits the primary users (PUs). Compared with centralized spectrum trading designs, e.g., spectrum auction, distributed spectrum trading better captures instantaneous spectrum trading opportunities over large geographical regions without incurring extra infrastructure deployment and control cost. However, existing distributed spectrum trading designs have limited concern about spectrum reuse. Considering spatial reuse, in this talk, I will present a novel distributed frequency reuse based opportunistic spectrum trading (D-FROST) scheme, which can further improve spectrum utilization, provide more accessing opportunities for SUs, and increase the revenues of PUs. In this study, we employ conflict graph to characterize the SUs’ co-channel and radio interferences, and mathematically formulate a centralized PUs’ revenue maximization problem under multiple wireless transmission constraints. Due to the NP-hardness to solve the problem and no-existence of centralized trading entity, we develop the DFROST algorithms based on dynamic matching with evolving preferences, and prove its stability. Through simulations, we show that the D-FROST algorithm is superior to other distributed spectrum trading algorithms without considering spectrum reuse, yields results close to the centralized optimal one, and is effective in increasing PUs’ revenue and improving spectrum utilization. Besides, based on D-FROST, I will also discuss some privacy preserving issues of distributed spectrum trading.
