Research on Fast Discovery of Spectrum Opportunities in CRSN
LI Xiao-pen · Microcomputer Information · 2010
As the development of the cognitive radio technology attracts more and more people's attention,the conflict between the discovery velocity of spectrum opportunities and the energy finitude in the cognitive radio sensor networks(CRSN) is more and more serious.In this paper,we explore the method of reasonable plans of sensing interval to solve the issue.We deduce the function of the discovery delay and the energy consume as the increase of the sensing interval in multi-channel condition.And also we explain the selection problems of the interval and the channel number through the simulation,which will be a great contribution to the realization of the CRSN.
