摘要:
Mobile network performance and user Quality of Experience (QoE) will be negatively affected by the explosion of mobile data traffic. Recent research has focused on local caching at the wireless edge, as motivated by the 80/20 rule regarding content popularity. By caching popular contents at base stations (BSs), backhaul congestion and content access latency can be dramatically reduced. To address the limited storage size of BSs, an algorithm optimizing cooperative caching has been highlighted. Contents requested by mobile users that cannot be obtained locally could be transferred by cooperativ...
