“…Palicot in [17] demonstrated how to achieve green radio communications by employing cognitive radio technology. Ji et al in [18] proposed a platform to explore TV white space in order to achieve green communications in cognitive radio network. Successful commercialization of new green cognitive technology, however, not only relies on sound engineering, but also depends on the proper design of a business model that provides sufficient incentives to the involved parties such as spectrum licensees and the network operators.…”

“…However, if user m only chooses the database's basic service, the database cannot predict its channel selection, and thus cannot compute its interference to other users.For convenience, we denote N[a] k as the set of users operating on TV channel k and subscribing to the database's advance service (i.e., those choosing the strategy s = a), and N [b]k as the set of users operating on channel k and choosing the database's basic service (i.e., those choosing the strategy s = b). That is,N [a] k N [b] k = N k .Then, for a particular user,• its experienced interference 18 (on channel k) known by the database isz k v k + m∈N [a] k w k,m ,(24)which contains the interference from TV licensees and all users (operating on channel k) subscribing to the database's advanced service.• its experienced interference (on channel k) not known by the database iŝz k o k + m∈N [b] k w k,m ,(25)18 We assume that this user has not decided which service to choose yet, and hence it is not in the set of N k .…”

A database-assisted TV white space network can achieve the goal of green cognitive communication by effectively reducing the energy consumption in cognitive communications. The success of such a novel network relies on a proper business model that provides substantial incentives for all parties involved. In this paper, we propose an integrated spectrum and information market for a database-assisted TV white space network, where the geo-location database acts as an online platform providing services to both spectrum market and information market. We model the interactions among the database operator, the spectrum licensee, and unlicensed users as a three-stage sequential decision process. Specifically, Stage I characterizes the negotiation between the database and the licensee, in terms of the commission for the licensee to use the spectrum market platform, Stage II models the pricing decisions of the database and the licensee, and Stage III characterizes the subscription behaviors of unlicensed users. Analyzing such a three-stage model is challenging due to the co-existence of both positive and negative network externalities in the information market. Nevertheless of this, we are able to explicitly characterize the impact of network externalities on the equilibrium behaviors of all parties involved. We analytically show that the licensee can never get a market share larger than half in the integrated market. Our numerical results further show that the proposed integrated market can outperform a pure information market in terms of network profit up to 87%.[3], the information and communication technology (ICT) infrastructures account for 3% of global energy consumption and 2% of global CO 2 emissions. Hence, energy optimization of wireless communications, ranging from equipment manufacturing to core functionalities, becomes increasingly important for protecting our environment, coping with global warming, and facilitating sustainable development.

“…A similar approach, named cognitive pilot channel (CPC) , has been also taken into account by the European Telecommunication Standardization Institute as a viable option for aiding the coexistence on the same spectrum resources of heterogeneous systems. The exploitation of the CPC has been taken into account also in , where the CPC is supposed to be piggybacked on a Terrestrial Digital Media Broadcasting framing structure.…”

Machine to machine (M2M) communications have gained in the last years an increasing interest due to ever growing number of machine-type devices that are used in different application fields by allowing low cost and efficient communications among devices mainly in an autonomous manner. Even if M2M protocols need of dedicated resources, a new paradigm called cognitive M2M (CM2M) has been recently introduced in order to exploit cognitive/opportunistic radio communications. The aim of this paper is to outline a CM2M mechanism, where the primary network is based on the orthogonal frequency division multiple access technique, while the M2M communication-based secondary network uses a novel medium access control technique, named data aided cognitive technique (DACT). The performance of the proposed DACT protocol is derived by means of suitable analytical methods under different operational conditions. Analytical predictions are also validated by comparisons with numerical results obtained through computer simulations, in order to show the effectiveness of the proposed solution in terms of throughput, delay, resource wastage and CM2M devices queue length; to this aim, the proposed DACT protocol has been implemented with different alternatives. Among them, an adaptive approach allows to optimise the system performance by increasing the overall throughput while keeping under control the system delay and the resource wastage.

Geo-location database-assisted TV white space network reduces the need of energy-intensive processes (such as spectrum sensing), hence can achieve green cognitive communication effectively. The success of such a network relies on a proper business model that provides incentives for all parties involved. In this paper, we propose MINE GOLD (a Model of INformation markEt for GeO-Location Database), which enables databases to sell the spectrum information to unlicensed white space devices (WSDs) for profit. Specifically, we focus on an oligopoly information market with multiple databases, and study the interactions among databases and WSDs using a two-stage hierarchical model. In Stage I, databases compete to sell information to WSDs by optimizing their information prices. In Stage II, each WSD decides whether and from which database to purchase the information, to maximize his benefit of using the TV white space. We first characterize how the WSDs' purchasing behaviors dynamically evolve, and what is the equilibrium point under fixed information prices from the databases. We then analyze how the system parameters and the databases' pricing decisions affect the market equilibrium, and what is the equilibrium of the database price competition. Our numerical results show that, perhaps counter-intuitively, the databases' aggregate revenue is not monotonic with the number of databases. Moreover, numerical results show that a large degree of positive network externality would improve the databases' revenues and the system performance.
