Due to the integration of different wireless technologies in heterogeneous environment, demand of ubiquitous connectivity is increasing day by day. Vertical handover is the mechanism to support seamless connectivity any time anywhere. Various approaches have been proposed in literature for network selection in vertical handover. In this work, an approach for vertical handover is proposed to reduce call blocking probability and optimal network selection algorithm. Three networks CDMA, WIMAX and WLAN have been considered for performance evaluation of proposed approach for network selection. SAW (Simple additive weighting), MEW (Multiplicative exponent weighting) and TOPSIS (Technique for order of Preference by similarity to the Ideal Solution) multiple attributes decision making (MADM) algorithms have been used for the selection of suitable network.
