Abstract
Future wireless communication systems will see the exponential growth in number of mobile devices and services. Quality of service (QoS) requirement is another aspect of the evolution of wireless communications and the explosive increase in number of devices, makes the fulfillment of this QoS requirement extremely challenging. Hyper dense small cell networks are an integral part of 5G environment. However, they can suffer from high interference and imbalanced distribution of users. Identifying weak users and helping them to achieve standard QoS requirement is a critical issue and challenge to handle. In this work, various technologies namely as joint transmission coordinated multi-point (JT-CoMP), non-orthogonal multiple access (NOMA), multi-user multiple-input multiple-output (MD-MIMO) and zero-forcing beamforming (ZFB) are used along with a cooperative coalition formation game. A static user scenario is developed in simulation environment, and a cooperative coalition game scenario with JT-CoMP is compared with No JT-CoMP, and results indicate the significant overall improvement over it.
