A New Technique of Auction Based Spectrum Allocation for CR Network
Jyoti Shivshankar Swami, Sangita Nikumbh
The survey of Federal Communications Commission (FCC) in 2002, shows that spectrum access is more significant problem than physical scarcity of spectrum. With many technological advances in the field of wireless communication the demand for radio spectrum has tremendously increased and with the standardization of MBMS (multimedia broadcast and multicast services) it has gained significant interest in the market. With the diversification of wireless communication services and the proliferation of different wireless network technologies, the demand for radio spectrum is increasing dramatically. However, spectrum measurements indicate that the allocated spectrum is not fully utilized, that is, there exists unused spectrum. Cognitive radio has attracted an increasing amount of interest over the past few years as an effective method of alleviating the spectrum scarcity problem in wireless communications. One of the most promising approaches in cognitive radio is the opportunistic spectrum access, which enables unlicensed users to access licensed frequency bands that are detected to be idle. We develop a truthful and efficient combinatorial auction scheme under a novel spectrum allocation model. Once the spectrum is sensed next important step for cognitive radio is allocation of available spectrum (The available spectrum holes, i.e., frequency bands assigned to a primary user but that are vacant in a given place at a given time, can be estimated with spectrum sensing).There are different spectrum allocation mechanism are available such as auction mechanism, first come first serve etc. We use auction mechanism in our project. According to the usage of secondary user in term of time and frequency and available spectrum primary operator (PO) allocate this spectrum on the basis of one time bidding of secondary users. The algorithm approach will be developed using Matlab environment
