Impact of mobility on spectrum sensing in cognitive radio networks

  title={Impact of mobility on spectrum sensing in cognitive radio networks},
  author={Alexander W. Min and Kang G. Shin},
In cognitive radio networks (CRNs), spectrum sensing is key to opportunistic spectrum access while preventing any unacceptable interference to primary users' communications. Although cognitive radios function as spectrum sensors and move around, most, if not all, of existing approaches assume stationary spectrum sensors, thus providing inaccurate sensing results. As part of our effort to solve/alleviate this problem, we consider the impact of sensor mobility on spectrum sensing performance in a… CONTINUE READING
