Dynamic spectrum access analysis in cognitive radio based wireless regional area network
Jayant P. Pawar, Prashant V. Ingole · 2016
Cognitive Radio (CR) [4] has a capacity to dynamically utilize the unused spectrum because of the advances in electronics and government policies. Dynamic spectrum access (DSA) [9] is the technique to utilize the free spectrum and release the current spectrum if the original user (incumbents) arises on that spectrum within channel move time. This paper analyzed the DSA characteristics in IEEE 802.22 based wireless regional area network (WRAN) through NETSIM version 8.2.
