Network selection method based on matching game in security risk network

Abstract

The invention requests to protect a network selection method based on a matching game in a security risk network. The method aims at solving the problem that user information is illegally stolen due to the fact that most of current vertical switching algorithms do not consider network access point safety and user safety requirements. The main idea of the method is as follows: firstly, sensing the historical internet surfing behavior of a user, and evaluating the security demand of the user; secondly, evaluating the security of the network access point through a decision tree algorithm; respectively designing satisfaction functions of the network side and the user side, and establishing satisfaction ranking value matrixes of the two sides; and finally, matching the user and the network through a matching game method. Simulation experiments show that the method can provide higher user satisfaction, and the total throughput of the system is not obviously reduced compared with other algorithms.

Description

technical field [0001] The invention belongs to the field of mobile communication, in particular to a network selection method in a risk network, in particular to a network selection method using a matching game method. Background technique [0002] In recent years, with the development of personal mobile communication systems, a single network often cannot meet the diverse needs of users, thus forming a heterogeneous wireless network environment based on multiple wireless access technologies. Different wireless network technologies overlap and overlap to bring users a variety of service experiences. How to select a network that meets user needs for access in a heterogeneous wireless network is an important challenge in the current network selection research field. [0003] The quality of network selection algorithm is related to user satisfaction and network performance. At present, scholars at home and abroad have also done a lot of research on the network selection algor...

Problems solved by technology

[0004] In the above algorithm, the selection of network indicators does not consider the security of the network access point in the network environment, and only considers the consideration of the user side and the network side instead of two-way considerations, resulting in illegal theft of user information
