Multiparameter Analysis for Distributed Storage Schemes in Wireless D2D Networks

Abstract

In this paper, we consider a novel wireless network for content distribute storage, where devices could use device-to-device (D2D) communication to transmit data. Several storage schemes, such as maximum distance separable (MDS) code and regenerating code, are employed for content downloading and repairing as node left and data lost. On the basis of multiparameter analysis, we found that targeting on the popular file caching, smaller download locality is the most suitable to the system based on fixed storage nodes and lower repair frequency. Moreover, MBR codes do not apply to D2D distributed storage due to high download cost, and MDS code is a convenient and appropriate scheme for majority practical D2D networks.
