Integration of Heterogeneous Networks on SAW, TOPSIS and AHP Methods

G.A. Preethi, Dr.C. Chandrasekar

Abstract


One of the major issues in next generation heterogeneous networks is the issue of vertical handoff for providing seamless integration and Quality of Service. Even though several approaches have been proposed to solve the handoff problem, we have proposed an enhanced method. The main objective is to provide a diverse range of high data transfer services across different wireless networks. In this paper we propose a Multiple Attribute Decision making method for providing the handoff decision. Our main goal is to provide easy and indisputable handoff decision methods suitable for heterogeneous networks. Vertical Handoff occurs when an active communication session is transferred between different heterogeneous radio access technologies. We are going to propose Simple Additive Weighting (SAW) method and compare with Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) and Analytical Hierarchy Process(AHP). Results show good performance of our proposed scheme over other two MADM Processes.
