“…Specifically, the hierarchical relationship between SBSs and users best suits the Stackelberg game model. In a classical Stackelberg game, one player acts as a leader and the rest as followers, and the main goal is to find an optimal strategy for the leader, assuming that the followers react in such a rational way that followers optimize their objective functions given the leader's actions [11,12]. However, in our dynamic Stackelberg game, game players can be leaders or followers dynamically.…”

For current and future cellular networks, small cell structure with licensed and unlicensed bandwidth, caching content provisioning, and device-to-device (D2D) communications is seen as a necessary architecture. Recently, a series of control methods have been developed to address a myriad of challenges in next-generation small cell networks. In this study, we focus on the design of novel D2D-enabled small cell network control scheme by allowing caching and unlicensed D2D communications. Motivated by game theory and learning algorithm, the proposed scheme adaptively selects caching contents and splits the available bandwidth for licensed and unlicensed communications. Under dynamically changing network environments, we capture the dynamics of the network system and design a new dynamic Stackelberg game model. Based on a hierarchical and feedback based control manner, small base stations and users can be leaders or followers dynamically while improving 5G network performance. Simulations and performance analysis verify the efficiency of the proposed scheme, showing that our approach can outperform existing schemes by about 5%∼15% in terms of bandwidth utilization, cache hit ratio, and system throughput.

Abstract:We study a non-cooperative game with aggregative structure, namely when the payoffs depend on the strategies of the opponent players through an aggregator function. We assume that a subset of players behave as leaders in a Stackelberg model. The leaders, as well the followers, act non-cooperatively between themselves and solve a Nash equilibrium problem. We assume an exogenous uncertainty affecting the aggregator and we obtain existence results for the stochastic resulting game. Some examples are illustrated.

Nowadays, wireless mobile services have been going through a paradigm shift due to three reasons: (i) the increasing needs for ubiquitous connectivity, (ii) an unprecedented volume of mobile data traffic, and (iii) technologically advanced mobile devices with enhanced capabilities. To address these challenges, user-provided network (UPN) is an emerging technology and can be extensively deployed with the aim of providing substantial improvements to cellular coverage and capacity. In this study, we focus on the design of novel UPN control scheme based on the game theory. Motivated by the Stackelberg game model, our proposed scheme allows mobile devices to play changeable roles, i.e., hosts or clients, to improve the UPN system performance. Under dynamically changing UPN environments, it is a suitable approach. Based on the decentralized, individual noncooperative manner, we capture the dynamics of UPN system while leading a deep progress for future networks. Simulations and performance analysis verify the efficiency of proposed scheme, showing that our approach can outperform existing schemes in terms of bandwidth utilization, quality of experience (QoE) of service success, delay and throughput ratios, and normalized users' profit.
