The emergent paradigm of edge computing advocates that computational and storage resources can be extended to the edge of the network so that the impact of data transmission latency over the Internet can be effectively reduced for time-constrained Internet of Things applications. With the widespread deployment of edge computing devices, the energy demand of these devices has increased and started to become a noticeable issue for the suitable development of urban systems. In this article, we prop...

By enabling sensor nodes to opportunistically access licensed channels, CRSN can provide a spectrum-efficient networking solution in the era of the Internet of Things. On the other hand, it also consumes extra energy for spectrum sensing and switching. This is a double-edged sword posing a dilemma between spectrum efficiency and energy efficiency. Recent advances in RF energy harvesting and transfer promote RF-powered CRSN in providing a promising way to address this challenge. In RF-powered CRS...

The TOF method is the most popular and efficient way to extract depth information in an optical sensing system, and TDC is generally used to measure the round-trip delay. In this article, a TDC with ~40 ps measurement resolution and very large linear dynamic range is proposed for optical sensing applications. Referenced to a single 100 MHz clock, the TDC incorporates a DLL and a VDL loop to automatically stabilize the measuring resolution, thus eliminating the need for a separate calibration ste...

Heterogeneous wireless networks (HWNs), composed of densely deployed base stations of different types with various radio access technologies, have become a prevailing trend to accommodate ever increasing traffic demand. Nowadays, users rely heavily on HWNs for ubiquitous network access to support critical applications such as financial transactions, e-health, and public safety. Cyber risks, representing one of the most significant threats to network security and reliability, are increasing in se...

With the prevalence of sensor-rich smartphones, MCS has become an emerging paradigm to perform urban sensing tasks in recent years. In MCS systems, it is important to minimize the energy consumption on devices of mobile users, as high energy consumption severely reduces their participation willingness. In this article, we provide a comprehensive review of energy saving techniques in MCS and identify future research opportunities. Specifically, we analyze the main causes of energy consumption in ...

The seven articles in this special section examine how 5G mobile communications will impact the smart healthcare industry. With the advancement of 5G communications, smart or "connected" healthcare is getting tremendous attention from academia, governments, industry, and the healthcare community. This will include, for example, 5G wireless networks, mobile edge computing (MEC), software-defined networking (SDN), and cloud radio access networks (C-RANs) can play a significant role in smart health...

Blockchain, as the backbone technology of the current popular Bitcoin digital currency, has become a promising decentralized data management framework. Although blockchain has been widely adopted in many applications (e.g., finance, healthcare, and logistics), its application in mobile services is still limited. This is due to the fact that blockchain users need to solve preset proof-of-work puzzles to add new data (i.e., a block) to the blockchain. Solving the proof of work, however, consumes s...

The use of fiber optic cable in support of bandwidth expansion has become de rigeur. Not only does optical fiber offer tremendous bandwidth, it is also low in attenuation, small in cross section, inexpensive, and impervious to electromagnetic interference, and there are significant economies of scale on components developed for the myriad of optical communications markets (long haul, fiber to the home, metro networks, etc.). Shorthaul requirements continue to grow and are expected to exceed the ...

The nine articles in this special section focus on mobile 5G heterogeneous mobile communication. It is widely agreed that B5G network should achieve greater system capacity (>1000 times) in terms of data rate (terabits per second) and user density (the Internet of Things and Nano-Things). Also, it is generally accepted that there are three major ways to obtain several orders of increase in throughput gain, those being extreme densification of infrastructure, large quantities of new bandwidth, an...
