Abstract
Mobile ad hoc networks (MANETs) have been widely used by individuals for residential or commercial usage in small-scale areas depending on fifth-generation (5G) and device-to-device (D2D) advancements. MANET demands extremely high system throughput, low latency, and best quality of service (QoS) maintenance. The current user mobility approaches only analyze the single movable user and use intuitive methods but cannot fundamentally solve multiple user cooperative mobility in practical applications. In this paper, we first jointly consider multiple user mobility and different geographical places and distances among all users. Then, we propose an interaction position game (IPG) to achieve high throughput and decrease computational cost. In this game, cooperative behaviors among movable users are proposed instead of assumed selfishness, as in traditional game models. In addition, we also present the simulated annealing (SA) algorithm to solve this NP-hard problem as a performance comparison. Finally, we evaluate the performance of this proposed game in various position cases. The results show that this game method improves the maximum throughput ratio evidently by 57.35% and 27.27% compared with the conventional intuitive method and SA algorithm, respectively. Compared with the exhaustive algorithm, this game reduces the computation cost by 82.79%.
Highlights
With the rapid development and evolution of wireless communication technologies, device-to-device (D2D) communication has attracted significant attention and is an indispensable technology in fifth-generation (5G) [1] networks, which demands exceptionally high data rates, large channel capacity, low latency, and quality of service (QoS) maintenance
The ad hoc network consisting of mobile devices can be called a mobile ad hoc network (MANET), which has been proposed in the IEEE 802.11 wireless LAN (WLAN) protocol [2]
RELATED WORK we present a brief overview of QoS in mobile ad hoc networks, the user cooperative mobility approach, and the application of game theory in wireless networks
Summary
With the rapid development and evolution of wireless communication technologies, device-to-device (D2D) communication has attracted significant attention and is an indispensable technology in fifth-generation (5G) [1] networks, which demands exceptionally high data rates, large channel capacity, low latency, and quality of service (QoS) maintenance. The waste of transmission time because of channel capture for one user causes a delay and increases energy consumption in the operational process To deal with these problems, some researchers proposed the user cooperative mobility approach to improve the overall throughput. Most researchers have concentrated on WLAN and limiting transmission distance [11], [12], but they have not proposed multiple new movable user mobility strategies until now. We focus on multiple movable user mobility and ad hoc networks without limiting transmission time and distance. We exploit cooperative behaviors among movable users rather than assuming selfishness as in traditional game models This IPG game-theoretic approach considers the interference impacts on other players in the optimal position while maximizing their throughput.
