The radio access network (RAN) cache is recently proposed to improve quality of experience perceived by mobile users on Internet content access and reduce intense pressure on the backhaul network. However, because RAN caches (e.g., associated with base stations) are located below mobility management entities in mobile core network, the continuity of content service for the handover users with unfinished...
Distributed and cooperative caches (DCCs) enabled small-cell network (SCN) has been a common approach for improving QoE perceived by mobile users (UEs) and reducing backhaul traffic load. In this paper, we propose a joint wireless and backhaul load balancing (JWBLB) framework for DCCs enabled SCNs with the objective to minimizing the system content transmission delay. The JWBLB is achieved through...
Distributed caching in the radio access network (RAN) has been a common approach for improving QoE per- ceived by mobile users and reducing backhaul traffic load. In this paper, we focus on the problem of cooperative and online searching and routing for content objects cached according to their local popularity in small- cell networks (SCNs), considering practical issues of implementation complexity...
