Performance Comparison of MADM Algorithms for Network Selection in Heterogeneous Networks

Vertical handover is a need of present era of heterogeneous networks comprising different network technologies. Lot of quality of service (QoS) parameters, user�s preferences, network conditions and other parameters participate in selection of appropriate network among available networks. This multi- criteria nature of vertical handover verifiesapplicability of multiple attribute decision making (MADM) algorithms to be used for network selection in heterogeneous networks. In this work, six MADM algorithms SAW, MEW, TOPSIS, GRA, AHP and VIKOR have been implemented. Performance of these algorithms has beenanalyzed for handover latency,number of handovers and optimum network selection. It was concluded that VIKOR algorithm is able to provide compromised solution in the light of these parameters
