Study on Selection of Heterogeneous Wireless Network in the View of Multi-Attribute Decision-Making

ABSTRACT

Heterogeneous wireless network in the future will provide users with more service selections. The user can select the network with the best effect based on the specific demand and individual preference, and random selection will not only cause disorder of the network and low load efficiency but also impact the user’s experience. The previous studies believe that the attribute of the network only has monotonous impact on the utility of user’s use, namely, the larger the efficiency indicator the better, and the smaller the cost indicator the better. However, in reality, it changes with the conditions. The study divides the users into two types of quality preference and cost preference based on the model of multiattribute decision-making and constructs the network selection model in the environment of heterogeneous wireless network targeted at the voice business, video business and data business by taking into account the decision attributes of network bandwidth, delay, response speed, safety, cost to use, etc., thus realizing the objective of increasing the network utility of the user under the circumstance of adding no load to the network.
