Abstract
In dynamic spectrum sharing, Wireless Service Providers (WSPs) can dynamically acquire spectrum by leasing from spectrum broker and sell spectrum to users. In this paper, we model the interactions between secondary WSPs and users as a three-stage game with objective of maximizing WSPs’ profits. The competitive WSPs make leasing strategies in stage I and pricing strategies in stage II. Users follow Wardrop’s principle and choose WSP with respect to price and quality of service (QoS) in stage III. We analyze the static game by means of backward induction. Given the users’ equilibrium, the pricing sub-game and leasing full game for competitive WSPs both have a unique Nash equilibrium. The situation without complete information is also studied by dynamic game. The short term pricing dynamic game converges to the Nash equilibrium of the pricing sub-game, while the long term leasing dynamic game converges to the Nash equilibrium of the full game.
