Abstract

The research on network switching technology is of great significance for seamless roaming of various terminals in heterogeneous wireless networks (HWNs). A personalized vertical handover decision algorithm considering terminal preferences in high-density access environments is proposed to address the dynamic characteristics of the network and the diverse needs of users. Based on the characteristics of the network, the algorithm maximizes the advantages of each network during high-density access, connecting more terminals to available networks with large connections as much as possible. In addition, criteria such as energy consumption and cost are selected to ensure terminal preferences, and a multi criteria decision making (MCDM) problem is constructed. The Analytic Hierarchy Process (AHP) is used to establish a judgment matrix, Determine the weights of each judgment criterion and ultimately select the network through utility function decision-making. The test results show that compared with the AHP based vertical switching algorithm, this algorithm eliminates the burden of networks and comprehensively considers terminal usage preferences during the pre screening stage. It can more accurately, fairly, and stably select the target switching network, reduce blocking rates and switching times, and more effectively improve the quality of user experience.
