A distributed resource management scheme for D2D communications based on coalition formation game

D2D (device-to-device) communications utilize the proximity between wireless users in the same cell, make the equipments directly communicate with each other, and dramatically improve the network performance. However, it also induces some urgent problems such as severe interference between the devices who share channels. In this paper, the resource management is investigated. Specifically, we model the joint mode selection and spectrum sharing problem as a coalition formation game. A distributed coalition formation algorithm is proposed, which aims at improving the sum achievable rate of the D2D communication system. Numerical results validate our algorithm, and show the proposed scheme can effectively improve the system performance.
