摘要: Cognitive Radio (CR) is one of the most transformative innovation recently emerged in field Wireless Networks. CR famous due to limited electromagnetic spectrum and fixed assignment policy. technology helps solve scarcity problem by using its intelligent radio which senses adapts environment. It locates unused allocated licensed users reallocate unlicensed thereby improving utilization spectrum. This paper points out various challenges limitations faced areas such as wireless sensor networks, vehicular smart grid, healthcare, public safety networks highlights improvements made well quality communication, makes these more efficient. An overview along with research domains are presented paper.
