Topic : A Survey: Detection Techniques on Selfish & Multi-Selfish Attacks in Cognitive Radio Networks

Authors:Vanitha K.C || Dr. Bharathi S.H , Vidyasagar K.N

Abstract:Cognitive radio network is a rare communication technology which suggests the Unlicensed persons to use more amount of bandwidth existing in the spectrum which is not used by licensed persons. CRN identifies large number of available communication channels in spectrum very efficiently. The free spectrum of CRN is used by the users who are Unlicensed without harming the licensed users (PU) which are involved in communication. The main goal of CRN is to solve the problem of Spectrum Scarcity by making the unlicensed user to use the spectrum when it is free that means when the licensed user (PU) will not use the spectrum that time the unlicensed user can use it dynamically. Advantage of CR is to provide efficient data transmission without the breakup in the comminucation.CRN faces problems on selfish attacks which are carried out by the SU which sends fake information to the person near to SU as that to occupy all free channels available in spectrum. Selfish SU Nodes and Multi-selfish SU Nodes are degrading the performance by sending fake message to closer nodes of CRN. Here we suggested how to identify Selfish and Multi-selfish SU nodes by the two different algorithms based on survey..

Keywords: Cognitive Radio Network (CRN), Secondary users (SU), Primary User (PU), Selfish Nodes, Multi-selfish nodes.
