Spectrum Handoff with Channel Sensing Sequencing in Cognitive Radio Network
Published 2013-04-01“…In the cognitive radio network,when the primary users show up,the secondary users should vacate the channel and find another free channel for data transmissions.This is the so-called spectrum handoff.There are two most important performance metrics for spectrum handoff:handoff delay and handoff times.A novel spectrum handoff scheme with channel sensing sequencing was proposed in order to decrease both handoff delay and handoff times.When designing the channel sensing sequence,the channel free probability was considered,and the probability that no handoff will happen in a channel was considered as well.The simulation results show that the method not only can get the minimum handoff delay as the traditional method does,but also can decrease the handoff times were significantly compared with the traditional method.…”

The Information Theoretic Approach to Signal Anomaly Detection for Cognitive Radio
Published 2010-01-01“…Efficient utilisation and sharing of limited spectrum resources in an autonomous fashion is one of the primary goals of cognitive radio. However, decentralised spectrum sharing can lead to interference scenarios that must be detected and characterised to help achieve the other goal of cognitive radio—reliable service for the end user. …”
