A Comparative Study of Routing Protocols in Cognitive Radio Networks
Shilpa S. Nayak, Aslam Durvesh · International journal of advance research and innovative ideas in education · 2016
Cognitive Radio Networks, comprise of cognitive, spectrum adaptive devices which are capable of changing their parameters, taking into consideration the radio environment so as to utilize the spectrum efficiently as well as to provide dynamic utilization to the secondary users. For this, an effective route setup becomes a dire necessit y so as to provide efficient transmission in a highly congested environment. This paper focuses on some of the obstructions during the establishment of route from sender to destination node. This paper also provides insight on some of the used protocols in the field of cognitive networks used to effectively setting up of routes by taking into consideration the different features for discovery of nodes providing minimal path for efficient transmission.
