Abstract
In 5G cellular networks, device-to-device (D2D) communication has undoubtedly become a general trend to increase spectral efficiency while reducing communication delay. In particular, D2D technology is able to bear more and more services, which help user-centred and personalized services in future wireless networks. However, several technical issues and challenges are associated with the deployment of D2D communications. In this paper, we tackle the spectrum allocation problem of D2D enabled cellular networks. By employing the major ideas of cooperative game theory, we design a novel two-stage resource allocation protocol based on the weighted utilitarian and meta bargaining solutions. The purpose of bargaining solutions is to clarify what could be the best solution when game players share a surplus that they can jointly generate. According to the main advantages of step-by-step interactive bargaining mechanism, our proposed solution takes various benefits in a rational way. Some simulation results and numerical analysis are provided to confirm the effectiveness of our two-stage bargaining approach and validate the accuracy of the proposed spectrum allocation scheme. Finally, we address some challenges and identify research areas for the future study.
Highlights
It is expected that the number of wireless mobile devices will surpass 50 billion by 2020, and that a 1000-fold increase in data rate is required to accommodate the explosive growth of data traffic in wireless services
Motivated by the two bargaining solutions, we develop a new two-stage spectrum allocation scheme for the D2D multicasting system
The Stackelberg Game based Resource Allocation (SGRA), Revenue Maximizing Resource Allocation (RMRA) and SARA schemes have introduced unique challenges to efficiently solve the spectrum allocation problem in the D2D multicast platform. They have attracted lots of attention due to their various advantages. Compared to these existing SGRA, RMRA and SARA schemes [5], [10], [11], we demonstrate that the proposed scheme attains a better performance during the D2D multicasting operations
Summary
It is expected that the number of wireless mobile devices will surpass 50 billion by 2020, and that a 1000-fold increase in data rate is required to accommodate the explosive growth of data traffic in wireless services. The D2D user devices in cellular networks can communicate by sharing the spectrum resources assigned to mobile user devices S. Kim: D2D Enabled Cellular Network Spectrum Allocation Scheme Based on the Cooperative Bargaining Solution increase the network spectral capability and improve energy efficiency and user experience [2]–[4]. To effectively allocate the spectrum resource, our proposed scheme adopts the main concept of weighted utilitarian and meta bargaining models. Our proposed approach can leverage the full synergy of self-adaptability from the interdependence among cellular users Due to these reasons, we can effectively allocate the limited spectrum resource in a fair-efficient manner.
