Cooperative game theory and auctioning for spectrum allocation in cognitive radios

摘要: This paper addresses the problem of spectrum sharing in cognitive radios where secondary users (SUs) cooperatively sense for identifying and accessing unoccupied bands. It is shown that sensing scenario can be modeled as a transferable utility (TU) cooperative game Vickrey-Clarke-Groves (VCG) auction mechanism used to allocate resources fairly each user. SUs form coalitions jointly spectrum. The worth SU calculated according work done coalition terms information obtained about primary user (PU) activity from resulting games are balanced superadditive gets pay-off her coalition. Depending upon their needs, use this bid bands through an VCG auction. provides with incentive truthfully demand socially optimal. concepts results illustrated using simple example.
