A Quitting Game Framework for Self-Organized D2D Mobile Relaying in 5G

Abstract

Offloading the network, minimizing the power consumption as well as reducing interference are important issues in wireless networks. These requirements mandate that future cellular networks need to use Deviceto-Device communication as a key enabler. To harness this solution, we propose a two-device system that combines cellular and Device-to-Device (D2D) communication in an uplink communication. We model this system as a quitting game where devices choose simultaneously either to continue or to quit transmitting over the cellular network. The devices will strategically choose whether to compete or to cooperate through mobile relaying. We first calculate the throughput and the outage probability in a fading channel. Then we find the Sub-game Perfect Equilibrium of this game by determining the pure and mixed Nash equilibrium of each subgame. Results show that the outage probability depends on the transmission power and the distance separating a device from its serving BS. The quitting decision of devices depends on the fraction of throughput they would get after quitting, on the quitting frame and on the quitting regret.

D2D Mobile Relaying Meets NOMA—Part I: A Biform Game Analysis

“…Game theory is a set of applied mathematical tools aiming to understand and solve decision-making problems, such as competing and independent actors during conflicts. It has been extensively used in wireless networks [16,17], and more specifically in solving cooperation and competition problems between devices over limited resources [18][19][20][21][22][23][24][25][26].…”
