Abstract: In a heterogeneous wireless environment, network selection is a strategic issue and has a significant impact on providing 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 proposes a model based on VlseKriterijumskaOptimizacija I KompromisnoResenje (VIKOR) under fuzzy environment and grey relational analysis (GRA) for the selection of suitable network in a heterogeneous wireless environment. Here, triangular fuzzy linguistic variables are used to handle the vagueness and subjectivity of the decision-making process. This study focuses on four alternatives such as universal mobile telecommunications system (UMTS), long term evolution (LTE), worldwide interoperability for microwave access (WiMAX) and wireless local area network (WLAN). A six evaluation criteria such as throughput, delay, jitter, packet loss, cost, security are considered for choosing the suitable network in heterogeneous wireless environment.
