Mobile edge caching, which exploits the content popularity information, can lead to significant reduction in network congestion and operation cost. However, designing an efficient cache update mechanism is challenging because imperfect prediction of time-varying content popularity and several cost factors such as cache update and backhaul costs mus...

Network slicing provides great opportunities for network service providers (SPs) to scale up and achieve higher revenue by enabling fast and efficient creation of new services and customizable networks for enterprises and user equipment (UEs). This can only be achieved at the expense of more complicated radio resource management and service/trading...

5G wireless systems will extend mobile communication services beyond mobile telephony, mobile broadband, and massive machine-type communication into new application domains, namely the so-called vertical domains including the smart factory, smart vehicles, smart grid, smart city, etc. Supporting these vertical domains comes with demanding requireme...

This paper studies the caching problem for heterogeneous small-cell networks with bandwidth allocation and caching-aware base station (BS) association. The caching control and bandwidth allocation problem aims at minimizing the request miss ratio. To solve this problem, we propose a Line-Search-based-Iterative (LSBI) algorithm which determines the...

Efficient content caching plays a crucial role in quality of service (QoS) enhancement and congestion mitigation of the backhaul and core networks for the fifth-generation (5G) wireless network, which must support a large amount of multimedia and video content. Wireless network virtualization (WNV) provides a novel paradigm shift in 5G system desig...

We propose a wireless virtualization framework based on the Stackelberg game model for resource allocation in downlink orthogonal frequency division multiple access (OFDMA) wireless networks. Specifically, the wireless virtualization model enables an infrastructure provider (InP) to effectively lease radio resources to multiple mobile virtual netwo...

Counterfeiting is one of the most serious problems in the consumer market. One promising approach for anti-counterfeiting is to attach a low-cost Radio-frequency Identification (RFID) tag to the product authentication. In this paper, we propose an RFID system for detecting counterfeiting products. This RFID system consists of the tag authentication...
