An intelligent selection method based on game theory in heterogeneous wireless networks

Abstract

In next‐generation networks, users can optimize the choice with seamless transfer of different access technologies to maximize cost saving and improve quality of service. In such heterogeneous wireless environments, users equipped with multimode wireless devices that can access rich media services via one or more access networks. These networks may differ in terms of monetary cost, coverage range, technology, available bandwidth, energy usage and so on. The new challenge faced by network operators is to ensure users always connect to the best available network, whenever they want and wherever they are or another word to stay Always‐Best‐Connected. Therefore, a new intelligent method is proposed here to optimize vertical handover in selection processes to ensure Always‐Best‐Connected in heterogeneous wireless networks. The proposed solution identifies a new game network selection model for choosing the best connections from different candidate wireless networks. The selected network should satisfy the typical user demands. The proposed selection model is implemented by using the non‐cooperative game model. The proposed solution is evaluated through in‐depth analysis and simulation‐based testing. Results clearly prove that the proposed solution exhibits the highest performance compared with other solutions. Copyright © 2016 John Wiley & Sons, Ltd.

Distributed ON/OFF switching and dynamic channel allocation: Decreasing complexity and improving energy efficiency

“…As a result, its computational complexity grows exponentially with the number of BSs, and the problem becomes intractable when is large. In recent years, the game theory tool has received significant attention, which can be adopted to solve the problems in noncooperative scenarios . The problem is formulated as a noncooperative game , where is the set of BSs as the players.…”

A distributed learning–based user association for heterogeneous networks

“…Based on the ability to communicate between players, games can be classified into 2 categories: noncooperative games and coalitional games or cooperative games. 30 Here, we introduce some game-theoretic notions to model the problem as a noncooperative game. A Game consists of a set of players, a set of strategies, and payoffs for players, which can be defined as follows:…”
