Software-defined networking and in-network caching are promising technologies in the next generation wireless networks. In this paper, we propose enhancing the quality of experience (QoE)-aware wireless edge caching with bandwidth provisioning in software-defined wireless networks (SDWNs). Specifically, we design a novel mechanism to jointly provide proactive caching, bandwidth provisioning, and adaptive...
In this paper, we study the energy-efficient resource allocation in software-defined mobile networks with mobile edge computing and caching. With the introduction of caching and computing functions in mobile networks, content sources need to be selected according to the distribution of contents in caches, the capability of computational resources and the status of networks. Moreover, the network needs...
Software-defined networking and mobile edge caching are promising technologies in next generation mobile networks. This paper proposes to jointly optimize bandwidth provisioning and caching strategies in software-defined mobile networks considering the quality of services and limitations of resources. The proposed scheme aims at maximizing gains from dynamically managing caches and efficiently utilizing...
Recently, there are significant advances in the areas of networking, caching and computing. Nevertheless, these three important areas have traditionally been addressed separately in the existing research. In this paper, we present a novel framework that integrates networking, caching and computing in a systematic way and enables dynamic orchestration of these three resources to improve the end-to-end...
Software-defined networking (SDN) and in-network caching are promising technologies in next generation wireless networks. In this paper, motivated by the flow control in SDN, we propose an approach to solve bandwidth provisioning problem in software-defined mobile networks (SDMNs) with jointly considering in-network cache under uncertain flow rate. We present a flow control problem supporting bandwidth...
Recent advances of loop interference cancellation techniques enable full-duplex relaying (FDR) systems, which transmit and receive simultaneously in the same band with high spectrum efficiency. Unlike the existing works, in this paper, we study the energy efficiency aspect of resource allocation in FDR systems. We consider a OFDMA cellular network, where a shared FDR is deployed at the intersection...
In mobile cloud computing (MCC) systems, the resource in both the cloud and the mobile network should be carefully managed. Cloud resource management and radio resource management have traditionally been addressed separately in previous works. In this paper, we propose to jointly study dynamic cloud and radio resource management so as to improve end-to-end performance of adaptive video transmissions...
