Coded caching is a promising method for solving caching problems in content-centric wireless networks. To enhance the security of coded caching for practical purposes, this paper investigates a secure coded caching scheme for defending against an eavesdropper who may possess prior knowledge before eavesdropping on content delivery. A novel key-base...

... the following, we present a series of numerical results and evaluate the performance of the proposed scheme in terms of the delivery rate and cache memory usage. The simulated model is as illustrated in Fig. 1, containing one central server, one α-strength eavesdropper and a number of users, each of whom has a cache of a certain size. All transmissions simulated in this model are transmitted over error-free broadcast links. Both the delivery rates and the cache memory sizes are divided by F to obtain their final values in the simulation ...

In this article, we study the scaling up of edge computing deployments. In edge computing, deployments are scaled up by adding more computational capacity atop the initial deployment, as deployment budgets allow. However, without careful consideration, adding new servers may not improve proximity to the mobile users, crucial for the Quality of Expe...
