Spectrum Pricing for Cognitive Radio

Wireless communications is becoming a key factor in developing of a modern society. It has grown phenomenally in the last decade and is now one of the most important infrastructures around the world. Different wireless technologies such as radio and television broadcast, transportation, alarm systems, remote control, medical equipment, meteorological and space research and public services, sensor, CCTV and other monitoring devices all require the use of the radio spectrum. The requirements of this technology vary in terms of data rate, transmission power, area of coverage; mobility, spectral and guard band requirement, making the radio spectrum have an unequal value to all transmissions. These requirements are changing from time to time as the modulation and data compression technology advance, leading to better technical efficiency in the use of the spectrum. However, despite the increasing number of equipment types using the spectrum, and improvements in spectral efficiency, the utilisation is not improving due to the static allocation of the spectrum. Static allocation of spectrum has led to wastage of the spectrum because it does not allow for flexibility of spectrum ownership and hinders innovation.

Dynamic spectrum management which would allow further sharing over space and time is expected to solve some problems presently encountered by the static allocation process and also provide high bandwidth to mobile users through its heterogeneous architecture.

The main aim of this research is to achieve dynamic spectrum management using pricing as an incentive for efficient usage in a cognitive radio system. Presently we have little knowledge about how Wireless Services Provider would be able to access unused spectrum in a dynamic manner under economic terms. This research would also aims at proposing some methods in which this can be done by using price as an incentive. The research also aims at developing a pricing mechanism that would be power efficient and would require less information in order to allow secondary access to the radio spectrum. The scheme would use price in formulating an economic model which would make efficient use of the radio spectrum. This research proposes a dynamic spectrum pricing scheme based on spectrum auction with minimum base price. The scheme should also help to determine the incentives needed towards more productive use of the spectrum.
