Area Spectral Efficiency Based Device-to-Device Communication

This paper suggested file delivery via device-to-device (D2D) communication, where the file is considered any content such as pictures, videos, etc. For a requesting file and considering the popularity of files, a general form of the success probability of the signal-to-interference-plus-noise ratio (SINR) is derived. Moreover, a simplified expression of the closed-form equation is approved. Zipf distribution, which depends on the popularity shape parameter α, is adopted to represent file popularity and utilized to model the file probability for the analysis of the achievable SINR. The Area Spectral Efficiency is studied, which depends on several metrics, including the success probability, n addition, good performance of the system is shown from the outcome results, where the success probability increased substantially with the increase of α, thereby enhancing the ASE accordingly. A Monte-Carlo simulation using the Matlab tool is performed to validate the theoretical results, where the results match perfectly.
