Abstract
The current development of mobile communication devices and the use patterns of these devices feature streaming services based on videos rather than services based on text data, images, and voice, as emphasized in the past. Hence, the amount of mobile traffic used by mobile communication device users has increased exponentially. The 5th generation (5G) mobile network technology offers several advantages compared to the existing 4th generation long-term evolution system technology, such as a capacity of data traffic greater by 1000 times, low latency, high energy efficiency, and cost efficiency. However, it cannot be easily provided compared with the latter because the use of a high frequency domain results in path loss. Hence, various technologies have been developed. This study proposes a hybrid method for applying both small cell and device-to-device (D2D) communication technologies for enhancing the performance of 5G mobile communication systems. Moreover, the performances of macro systems applying small cell technology, D2D communication technology, and the proposed hybrid method are compared. The analysis results indicated that the system performance was improved by using small cells and D2D in 5G mobile communication systems and overcoming the disadvantages of shadow areas and path loss issues, and the performance of 5G communication could be drastically enhanced by applying the algorithms of the small cell and D2D technologies as well as the hybrid algorithm between the two technologies.
