The next generation wireless networks are envisioned to follow the philosophy of buy when required, when it comes to the CApital EXpenditure (CAPEX) of operators over the infrastructure installation or extending new and dynamic resources. The dream of open market for new entrants and their coexistence with giant operators can be realized by the fancy concept of virtualization, which will be one of the key technologies in the future networks specially in the wireless part. Future virtualized mobile networks will comprise of a large number of (small) operators all competing for the spectrum resources. Such a scenario motivates and provisions the dynamic resource trading framework. This paper aims at presenting the realization concept of a dynamic spectrum trade market of future. We use the virtualized Long Term Evolution (LTE) as a realization framework for the proposed auctioned based dynamic spectrum sharing. We also investigate the profit function of spectrum broker and operators. We also study the realization of dynamic spectrum allocation on very small time instances (seconds) and investigate how the reservation price tunes the stake-holders’ profit and resource allocation efficiency. The spectrum trade is based on the single auction multi-bid format and the paper further studies the impact of false bidding on the profit of spectrum broker (or network infrastructure provider).
