Abstract
Device-to-Device (D2D) communication is becoming more popular research topic among the network researchers and engineers across the globe This popularity is due to various key applications of D2D communications including 4G LTE-A envisioning the continuous evolution of current cellular networks into 5G to support a much larger and diverse range of applications. D2D communications play an important role to fulfill the quality of service (QoS) requirements for 5G networks. However, to realize the performance gain of D2D communications, various open challenges need to be resolved including mode selection (MS). This paper, therefore proposes a new mode selection algorithm for D2D enabled heterogeneous 5G cellular network. By quantifying the key parameters we mitigate interference that affect the system performance, and finally proposed an algorithm for optimal selection of transmission mode in a heterogeneous cellular network. The findings reported in this paper provide some insights into the design of 5G networks that may help network designer and engineers to contribute further towards the development of next generation wireless networks.
