Near Field Communication over Cognitive Radio Networks: An Overview
Krishna Reddy, Biswanath Dey · SSRN Electronic Journal · 2018
With rapid advances in Personal Area Networks (PAN), the last decade has witnessed a growing demand for Wireless Devices and its Applications. However fixed spectrum assignment policies from ISM bands become inefficient, because of under-utilization of licensed spectrum for all time. To overcome spectrum requirements for PAN better strategies may need to dynamically utilize radio spectrum aimed to meet higher throughput parameters, QoS requirements as well as mobility and Cognitive Radio (CR) Technology can propose solutions in this direction. Whereas numerous challenges are involved in this direction over heterogeneous parameters such as MAC layer, Routing issues, Security issues, etc. Moreover with this influence, revision may need over upper layer protocols. Finally, at dense population areas, at present new direction Cognitive Radio Personal Area Networks (CR-PAN) may recommend over smart devices without predefined infrastructure, to gain an increased traffic performance over mobility and availability through CR, where users independently determine their own spectrum operating parameters widely at threshold level.
