On the Coded Caching Delivery Design over Wireless Networks
Lei Zheng, Qifa Yan, Qingchun Chen +1
Coded caching scheme is a promising technique to migrate the network burden in peak hours, which attains more prominent gains than the uncoded caching. The coded caching scheme can…
The Optimal Placement Delivery Arrays
Minquan Cheng, Jing Jiang, Qifa Yan +2
In wireless networks, coded caching is an effective technique to reduce network congestion during peak traffic times. Recently, a new concept called placement delivery array (PDA)…
Placement Delivery Array Design through Strong Edge Coloring of Bipartite Graphs
Qifa Yan, Xiaohu Tang, Qingchun Chen +1
The technique of coded caching proposed by Madddah-Ali and Niesen is a promising approach to alleviate the load of networks during busy times. Recently, placement delivery array (P…
On the Gap Between Decentralized and Centralized Coded Caching Schemes
Qifa Yan, Xiaohu Tang, Qingchun Chen
Caching is a promising solution to satisfy the ongoing explosive demands for multi-media traffics. Recently, Maddah-Ali and Niesen proposed both centralized and de-centralized code…
