Performance Analysis for Wireless Distributed Storage via D2D Links

This work investigates the performance for D2D enabled wireless caching in distributed storage system by taking the typical erasure correcting code namely maximum distance separable (MDS) into consideration. Targeting on the minimization of the transmission cost for content sharing, the spectrum resource allocation is optimized based on their statistical channel state information (CSI). To evaluate the quality of D2D links, two cases are considered with different assumptions for whether those physical links are stable or not regarding to mobility impacted user behaviors. Numerical results demonstrate the effectiveness of the proposed scheme.
