A Multi-Criteria Decision Making (MCDM) network selection model providing enhanced QoS differentiation to customers

Abstract

This paper proposes a radio resource management framework for integrated network selection mechanism control in multi- network environment as an interaction between the service providers and users in competitive manner to admit high priority users or the services that maximize their rewards. The proposed scheme comprises of three steps namely as user profile, service profile and access network selection. The priorities are assigned to the users depending on their grade and category. The users belonging to same categories have same preferences for the decision factors (or QoS parameters). Different policies are defined according to the network load to prioritize high priority users as compared to the type of service requested. The access network selection mechanism calculates the payoffs based on their relative weights calculated using AHP and a utility function evaluation by each wireless network for each user. The proposed model is preliminary and its contribution is to create an admission policy that can adapt to different coverage areas of a wireless network and depends on the priority of users and their requirements.
