In upcoming world the communication among heterogeneous wireless networks is a challenging task. Since the access technologies of various networks are different and while interoperable operations, some technical issues may occur. Handoff is an important method can provide solution for making interoperability among heterogeneous networks. Handoff method is purely depends on the attributes of the network such as bandwidth, delay, signal quality, reliability, and energy, access cost and so on. Handoff decision can be obtained by investigating the attribute values and various MADM methods such as SAW, MEW, TOPSIS and GRA are proposed already. In this paper EMADM - [Extended Multiple Attribute Decision Making] approach is proposed to choose the optimized attribute values for decision making using AIS-[Artificial Immune System]. Performance is evaluated by analyzing and comparing the obtained performance metrics with the existing approaches.
