Heterogeneous wireless network selection using FAHP integrated with TOPSIS and VIKOR

The selection of the most appropriate network in heterogeneous Wireless environment is one of the critical issues to provide the best Quality of Service (QOS) to the users. The selection of an apt network among various alternatives is a kind of Multi Criteria Decision Making (MCDM) problem. This paper describes a novel Multi Criteria Decision Making (MCDM) method to evaluate and select the suitable network for homogeneous wireless network environment. The proposed MCDM technique involves Fuzzy Analytical Hierarchy Process (FAHP) is integrated with Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) and VlseKriterijumska Optimizacija I Kompromisno Resenje in Serbian (VIKOR) techniques. FAHP is used to determine the criteria weights, whereas TOPSIS and VIKOR used to find the performance ranking of the alternative networks. This study focuses on five network alternatives such as WLAN, GPRS, UMTS, WIMAX, and CDMA and ten evaluation criteria such as bandwidth, latency, jitter, BER, Retransmission, Packet loss, through put, preference, security, cost to select the appropriate network.
