Wireless caching at network edges (in user devices or in base stations) is considered to be a promising solution to alleviate backhaul overload in future wireless networks. Device-to-Device (D2D)-assisted caching emerges as an attractive option. Due to the nature of D2D communications, social networks and the characteristics within are intertwined with the challenges in mobile device caching, and...
Data center interconnected by flexi-grid optical networks is a promising scenario to meet the high burstiness and high-bandwidth requirement of data center application, because flexi-grid optical networks can allocate spectral resources for applications in a dynamic, tunable and efficient control manner. Meanwhile, as centralized control architecture, the software defined networking (SDN) enabled...
Cellular controlled Device-to-Device (D2D) system is a local service for future communication systems like LTE, LTE-A, etc. D2D communications can share the Uplink (UL) or Downlink (DL) resources with cellular communications to improve system throughput. Since reusing UL resource or DL resource has different merits in different scenarios, if D2D only reuses either UL or DL resource during the whole...
Mobile WiMAX's scheduling service is a key factor in Radio Resource Management (RRM) in realizing Quality of Service (QoS). The choice in scheduling algorithm for Mobile WiMAX base stations, albeit outside of the scope of the standard, critically impacts the performance and robustness of Mobile WiMAX networks. This paper provides an in-depth study of four major scheduling algorithms: Round Robin (RR),...
