It's a challenging task and important technical issue when it comes to mobility management between multiple wireless technologies among different users. Cognitive Radio Network(CRN)is the solution for utilizing the bandwidth of all spectrums efficiently. The Spectrum is used by the Secondary user(SU) in the absence of Primary user(PU). Secondary user needs to vacate the channel when primary user starts to interrupt as it is the licensed user. To continue the seamless communication secondary user needs to occupy other channel. Multiple Attribute Decision Making (MADM) methods are most appropriate for handoff in CRN. Vlsekriterijumska Optimizacija l KOm- promisno Resenje method (VIKOR) is one of MADM method used for handoff process and is considered better than Simple Additive Weighting (SAW) and Multiplicative Exponent Weighting (MEW). The proposed method has 12% better results than VIKOR in channel selection by means of simulation in MATLAB based on relative standard deviation. Values of attributes within Telecom standards are considered for simulation purpose. © 2018 IEEE.
