Handover decision making based on multiple attributes in heterogeneous wireless networks

Abstract

This paper presents a methodused to make decision in handover based on multiple attributes to analyze and evaluate the results of selection of the optimal target network for transferring in heterogeneous wireless networks. The focus is on the combination of the fuzzy method FAHP to define weights of the criteria and TOPSIS method to make decision in selecting the network. A model with energy efficientis compared with other models with only the basic criteria of QoS, security, and cost in transfer deision making. Our experimental results indicate that with the same set of parameters, additional energy efficient will result in selecting the better access network.
