Nowadays, the number of mobile devices have increased rapidly, and require different amounts of spectrum with the limited carrier resource. As an emerging technique, multi-flow carrier aggregation (MCA) has been recently proposed to improve the capacity of 5G heterogeneous network systems. In this paper, we present an effective MCA control scheme for the future heterogeneous network (HetNet). With the MCA-enabled HetNet, we aim at maximizing the system throughput while considering each mobile device's benefit. To strike an appropriate performance balance between network operators and mobile users, our proposed scheme is designed as a two-level game model. The upper and lower level games are developed as different type game models, and work together interactively to reach a fairefficient spectrum allocation solution. Our hierarchical game approach can achieve reciprocal advantages, and clarifies what is the best solution for the MCA-enabled system. Using extensive simulations, we compare the performance and confirm the superiority of our game-based approach. Finally, the conclusions are presented, and some research challenges are identified for the future study.

Price-based power control problem is investigated in the spectrum sharing cognitive radio networks (CRNs) by Stackelberg game. Using backward induction, the revenue function of the primary user (PU) is expressed as a non-convex function of the transmit power of the secondary users (SUs). To solve the non-convex problem of the PU, a branch and bound based price-based power control algorithm is proposed. The proposed algorithm can be used to provide performance benchmarks for any other low complexity sub-optimal price-based power control algorithms based on Stackelberg game in CRNs.

“…Nevertheless, finding a stable coalition structure in an overlapping coalition formation game remains an exhaustive and notoriously difficult task. 23 Initiating cooperation in the wireless networks in the absence of a centralized controller is a dynamic process. Therefore, it is difficult but highly desirable to design practical distributed algorithms that can establish cooperation without relying on centralized entity.…”

“…If so happens, there is a transition from the existing structure to a new one and the corresponding feasible coalition structure is considered the new test structure. This process ends and flag is reset when we get the similar initial and test structures; otherwise, the initial structure is updated as the test structure and process for checking the instability continues (lines [12][13][14][15][16][17][18][19][20][21][22][23]. The test structure obtained at the end of the process is the stable coalition structure (line 24).…”

A coalitional game‐based integrated framework for optimal power allocation in multirelay cooperative environment

SummaryCooperative relaying has emerged as an efficient transmit strategy in wireless networks affected by fading. In multirelay scenarios, the performance of cooperative systems is heavily influenced by resource allocation among the available relays. However, in practical scenarios, a relay may not help unless the cooperation improves its own utility. To address the above problem, this paper introduces a novel integrated game-theoretic framework that involves incentivebased optimal power allocation among the cooperating relays. Coalition formation game has been used to model the cooperation among relays that is integrated into a Stackelberg game, for considering the benefits of source and relays jointly. The game theoretic framework has been implemented with an objective to find an optimal and stable coalition set of relays that not only maximizes their utilities but also helps the source to allocate the optimal power to the relays at the optimal price, thereby increasing its utility too. Simulation results have confirmed that the proposed game theoretic solutions achieve comparable performance in system throughput as compared with the centralized approach. Relay communication is a promising exemplar for future wireless networks. Through relaying, cooperative communication can enhance performance, reduce battery consumption, increase network lifetime, and improve throughput of the systems. 1 Ubiquitous systems defined by International Telecommunication Union require at least 10 times higher data rate than that fulfilled in legacy cellular networks. To obtain such high data rates without increasing the number of base stations and operating costs, it is necessary to introduce relay-assisted communication in general and cooperation between individual relays in particular. The relay-based architecture and cooperative multipath technologies have attracted much attention worldwide. Today, most of the standards for future mobile communication systems viz 3GPP, 3GPP2, B3G, and 4G, Wireless Local Area Network, and broadband wireless networks (IEEE 802.16j) utilize the concept of relaying and frequently take into account the problems related to relay-assisted communication and cooperation. 2 The Wireless World Initiative New Radio project has a detailed planning for ubiquitous broadband mobile radio relaying system. 3 In relay systems, energy efficiency is considered as one of the most important issues because the power of mobile users is a scarce and limited resource. 4 With the combination of relaying and other emerging technologies,
