Long-Range Wide-Area Network (LoRaWAN) has been increasingly deployed to serve as the wireless networking platforms for various Internet-of-Things applications. However, an inherent drawback of LoRaWAN is that the signal transmissions of LoRaWAN end devices frequently collide with each other, which leads to data decoding failure. This is because LoRaWAN enables wireless channel access mainly based on the naive ALOHA protocol where each end device is allowed to transmit regardless of others' ongoing transmissions. In this context, the past few years have witnessed the prosperity of enhanced channel access protocol design for LoRaWAN. Particularly, carrier-sense multiple access (CSMA) has gained more attention recently since it enables channel access in a distributed manner without additional signaling overhead between LoRaWAN end devices and gateways. More importantly, implementing CSMA in LoRaWAN is a challenging and interesting problem since signals in LoRaWAN can traverse below the noise floor, making traditional carrier-sensing techniques fail to detect ongoing transmissions. By considering the necessity and importance of this topic, this article aims to provide a comprehensive and timely review of CSMA-based LoRaWAN for the first time. We start by analyzing the trends of existing LoRaWAN-oriented CSMA studies. As the key possible technique to enable CSMA in practical LoRaWAN, Channel Activity Detection (CAD) and its associated challenges are then deeply investigated with a real-world measurement study. Based on the limitations of CAD, we finally provide several research insights for CAD-based CSMA in LoRaWAN.

This paper proposes a heterogeneous carrier-sense multiple access (CSMA) protocol named LoHEC as the first research attempt to improve energy fairness when applying CSMA to Long-Range Wide-Area Network (LoRaWAN). LoHEC is enabled by Channel Activity Detection (CAD), a recently introduced carrier-sensing technique to detect LoRaWAN signals even below the noise floor. The design of LoHEC is inspired by the fact that existing CAD-based CSMA proposals are in a homogeneous manner by having LoRaWAN end devices perform identical CAD regardless of the differences of their used network parameter-spreading factor (SF). This can lead to energy consumption unbalance among end devices since the consumed energy during CAD is significantly affected by SF. By considering the heterogeneity of LoRaWAN in terms of SF, LoHEC requires end devices to perform different numbers of CAD operations with different CAD intervals during channel access. Particularly, the number of needed CADs and CAD interval are determined based on the CAD energy consumption under different SFs. We conduct extensive experiments regarding LoHEC with a practical LoRaWAN testbed including 30 commercial off-the-shelf end devices. Experimental results show that in comparison with the existing solutions, LoHEC can achieve 0.6-0.8× improvement of the energy fairness on average.

This letter proposes a novel technique named LiCo to resolve LoRa signal collisions. Unlike existing approaches that introduce considerable computational overhead due to redundant LoRa demodulation operations, LiCo aims at a more lightweight way by simply performing one-shot demodulation regarding all colliding signals. For the separation of colliding signals, LiCo further analyzes the demodulation results in a comparative manner with no need to apply any complicated arithmetic. Theoretical and experimental results show that LiCo can reduce the computational overhead while achieving similar collision resolution performance as the state of the art.

Wireless power transfer has emerged as a promising technology to prolong the lifetime of Internet-of-Things (IoT) systems. To improve the effectiveness of this technology, mobile chargers (MCs) are particularly employed to travel inside an IoT system to wirelessly charge IoT devices. However, while extensive research is carried out, neglecting the relative locations of IoT devices dramatically degrades network performances particularly in terms of system charging efficiency, i.e., the ratio between obtained energy of IoT devices and consumed energy by MCs. Therefore, this paper presents a virtual mobile charger-based wireless power transfer strategy, VirCh, that aims at providing high charging efficiency for a large-scale IoT system composed of a base station (BS), multiple energy-constrained MCs, and massive IoT devices. The basic idea is that VirCh dispatches several virtual MCs to charge the IoT devices in the vicinity of the BS while having other MCs move along the shortest Hamiltonian cycle to charge the relatively remote ones. Simulation results validate the superiority of VirCh over state-of-the-art studies in terms of the system charging efficiency.

Recognizing if two objects are in close physical contact (CPC) is the basis of various Internet-of-Mobile-Things services such as vehicle proximity alert and radiation exposure reduction. This is achieved traditionally through proximity sensors that proactively transmit wireless signals and analyze the reflection from an object. Despite its feasibility, the past few years have witnessed the prosperity of reactive CPC detection techniques that merely exploit received wireless signals from a target. Unlike existing approaches entailing additional effort of multiple antennas, dedicated signal emitters, or human intervention, this paper presents TONARI, an effortless CPC detection framework that performs in a reactive manner. Particularly, TONARI is developed firstly with LoRa, the representative of unlicensed Low Power Wide Area Network (LPWAN) technologies, as the wireless signal for CPC detection. At the heart of TONARI lies a subtle feature arbitrator aiming to distinguish different types of LoRa chirp-based additive sample magnitude sequences. TONARI further includes a LoRa chirp mapping operation and makes final decision based on multiple received packets. Experiment shows that TONARI can achieve the CPC detection accuracy of 100% in most practical cases.

The last decade has witnessed the ever-increasing deployment of Wi-Fi networks and the explosion of Bluetooth-based applications. As a result, the coexistence of Bluetooth piconets with highly-dense Wi-Fi networks is a common phenomenon currently. Unlike Wi-Fi that conducts carrier sensing before channel access, Bluetooth adopts frequency hopping based on a predefined hop sequence, which inevitably incurs considerable cross-technology interference to Wi-Fi. While the Adaptive Frequency Hopping technique is standardized for interference reduction, it does not perform well in current practice where densely-deployed Wi-Fi networks commonly cover the whole 2.4 GHz unlicensed spectrum. In this context, this article presents BuSAR, a novel approach to account for the coexistence problem between Bluetooth piconets and dense Wi-Fi networks. BuSAR embodies the first work to aim at mitigating the cross-technology interference between Bluetooth and highly-dense Wi-Fi networks in a distributed manner. At the heart of BuSAR lies a subtle technique called Bluetooth slot availability randomization, which exploits the redundancy of erroneous Bluetooth packets for better Bluetooth/Wi-Fi coexistence. With BuSAR adopted, multiple Bluetooth piconets are guaranteed to operate independently and only a lightweight algorithm is needed to be implemented at each Bluetooth device. Both theoretical analysis and experimental results validate the feasibility and superiority of BuSAR.

This letter presents ZIP (zero-effort ZIgBee Proximity detection), a novel technique to detect the proximity of two Internet-of-Things devices. Based on the ZigBee technology, ZIP embodies the first zero-effort solution by differing from existing ones that resort to the use of tailor-made hardware, multiple antenna installments, the employment of a third-party device, or user involvement. At the heart of ZIP is the construction of a feature-designated decision tree built on received signal strength. An ensemble prediction method is further designed to aggregate the outputs of multiple decision trees for detection accuracy improvement. Practical experiments are conducted to show the reliability and robustness of ZIP.

The prosperity of IEEE 802.11-based Wi-Fi networks aggravates cross-technology interference to IEEE 802.15.4-enabled ZigBee networks widely deployed to enable various Internet-of-Things applications. To make ZigBee communication reliable and robust even in a dense Wi-Fi environment, taming Wi-Fi interference in ZigBee networks especially from the perspective of physical layer is of paramount importance. In this context, this work takes aim to design a novel Wi-Fi interference-resilient ZigBee decoder called PolarScout, which separates collided ZigBee signal samples out of Wi-Fi interference to bootstrap ZigBee data decoding. Unlike several existing solutions which need clear signal preamble, tremendous signal strength difference between ZigBee and Wi-Fi, and Wi-Fi interference recognition in prior to ZigBee decoding, PolarScout aims at direct ZigBee decoding in a more generic and challenging case where Wi-Fi interference features a wide range of power levels and arises within a ZigBee packet at an arbitrary position. At the heart of PolarScout lies a subtle shell-shaping technique which harnesses a customized sample sequence to smooth the shell of corrupted signal samples. PolarScout then refers to the resulting shell to recover each contaminated ZigBee sample. Experimental results validate the superiority of PolarScout and its resilience to a wide range of Wi-Fi interference types.

Recent studies figure out that hidden eavesdroppers can be detected through RF (radio frequency) leakage from their local oscillators. Inspired by this finding, this letter presents Phantom Eavesdropping, an emerging wireless signal eavesdropping technique which renders hidden eavesdroppers immune to the RF leakage-based detection to further conceal their presence. At its heart is a dynamic alteration process regarding the local oscillator's oscillation frequency. As a result, the RF leakage from the local oscillator is whitened in the frequency domain and thus the corresponding eavesdropper becomes footprint-less. Practical experiment shows that Phantom Eavesdropping does not affect normal Wi-Fi eavesdropping while further rendering eavesdroppers transparent to eavesdropper detectors.

This letter presents detect Wi-Fi signals out of ZigBee (DeWOZ), a clean-slate technique to discern Wi-Fi packets drowning in ZigBee interference. Unlike existing solutions that are restricted to the cases where Wi-Fi signal strength is much higher than ZigBee, Wi-Fi signals only interfere with ZigBee payload, or beforehand clear Wi-Fi transmissions are done to obtain transmitter-specific information, DeWOZ aims at achieving the detection of relatively weak Wi-Fi signal hidden in both ZigBee header and payload portions only based on a single corrupted signal. DeWOZ re-explores the Wi-Fi-oriented Schmidl-Cox algorithm for corrupted signal synchronization followed by two key operations, autocorrelation anomaly detection and adaptive discrete Fourier transform, to sniff Wi-Fi out of ZigBee header and payload, respectively. The feasibility of DeWOZ is validated via practical experiment.

The ever-increasing deployment of Wi-Fi and ZigBee networks aggravates cross-technology interference (CTI) in the 2.4 GHz unlicensed spectrum. This letter presents a clean-slate technique, DOTA, to combat the CTI and enable ZigBee/Wi-Fi co-transmission. Unlike existing solutions merely handling Wi-Fi-to-ZigBee interference, DOTA accounts for the true sense of CTI wherein ZigBee and Wi-Fi interfere with each other. At the heart of DOTA lies two operations, signal polishing and pulse disambiguation, for decomposing and threading signal samples to recover contaminated ZigBee and Wi-Fi signals. Experiment results validate the feasibility of superiority of DOTA.

Wireless power transfer technique aiming at wireless energy provision has emerged as a prominent solution to the architecture of long-term and self-sustainable wireless systems. Particularly, by integrating this approach with data communication, radio frequency (RF)-powered networks such as radio frequency identification systems have been ubiquitously deployed in recent years and are considered as one of the key components of both the Internet of Things and the Fourth Industrial Revolution. However, the lack of function diversity at end devices makes the conventional RF-powered networks merely support some simple and dull operations. In this context, various types of new devices with more intelligence and the ability of harvesting wireless power have been designed of late. Unfortunately, inevitable energy loss occurring in wireless propagation usually leads to time-consuming power transfer and network throughput degradation. Bearing this in mind, in this paper, we present a blueprint for the construction of next-generation RF-powered networks which intend to provide flexible network functions, prompt wireless power transfer, and high network throughput. Several relevant challenges and opportunities are also provided as a guidance on the formation of this new architecture-based Internet of Things.

By collecting data from sensor devices, wireless sensor networks enable consumer product management in indoor environments. However, most off-the-shelf sensor devices are battery-powered and hence hampered by the limitation of battery life. In this context, wireless rechargeable sensor networks (WRSNs) which adopt wireless power transfer (WPT) technique - leveraging electromagnetic waves for sensor energy replenishment - have emerged as a promising scenario for the architecture of self-sustainable and resilient sensor networks. Nevertheless, while the rapid proliferation of studies on discussion WPT and data collection in WRSNs has been witnessed in recent years, their unilateral investigation makes them insufficient to construct high-performance WRSNs. Therefore, this paper firstly explores joint WPT and data collection in a WRSN and accordingly presents a medium access control protocol called FarMac. The WRSN employs multiple sink nodes which can either conduct WPT to or data collection from numerous deployed sensor devices. The sensor devices, on the other hand, fall into two categories: lethargic sensor device which needs energy replenishment from the sink nodes before conveying its data and energetic sensor device which can disseminate its data directly. In this context, FarMac leverages a centralized algorithm to achieve multisource WPT for maximizing the transferred power to a lethargic sensor device. In addition, each lethargic sensor device executes a distributed algorithm to compute its necessary energy harvesting time. Furthermore, FarMac achieves concurrent WPT and data collection through interference cancellation technique. Simulation results demonstrate that FarMac improves network throughput by up to 41% compared with a benchmark approach and guarantees network resilience 1.

Radio frequency identification (RFID) technology provides a promising solution to the problem of missing object identification in large-scale systems, such as warehouses and bookstores by employing RFID readers to communicate with numerous RFID tags, each of which is attached to a monitored object. To achieve prompt identification of missing tags/objects, extensive research is carried out while the transmission of expatiatory bits from each tag and the occurrence of substantial tag collisions critically degrade the time efficiency. Therefore, this motivates us to propose ProTaR, a probabilistic tag retardation-based protocol, which addresses the missing tag identification problem in a more time-efficient way than the prior work. Based on an improvement of conventional frame-slotted ALOHA algorithm, ProTaR aims at alleviating the tag collision problem and achieving compact tag transmissions. The novelty of ProTaR is manifested mainly in two aspects. ProTaR leverages a mask at a reader to distill partial bits from 96-bit identifier (ID) of each tag for the characterization of tag uniqueness. In this context, ProTaR averts the transmission of redundant bits from both the tags and reader. A bit vector is constructed by the reader to inform each tag of the transmissions of others. This idea successfully eliminates the tag collisions, and hence makes full utilization of tag responses. Experimental results validate that ProTaR achieves 100% identification accuracy regardless of missing tag ratio. Furthermore, extensive simulations present that ProTaR enables the time efficiency improvement of up to 88% compared with benchmarks while merely degrading the optimum by 15%.

In recent years, RFID has increasingly been found in our daily life with various applications such as Internet of Things (IoT) and wireless sensor networks. However, considering a large-scale RFID system, collisions occur when multiple tags transmit signals to RFID reader simultaneously, thereby we observe significant degradation of the efficiency of these applications. Besides, in practice, since tags may move into or out of the transmission range of an RFID reader, three different types of tags coexist: dwelling tags, arriving tags, and leaving tags. In this context, it is necessary to design a novel anti-collision protocol which can distinguish them to achieve efficient tag identification. Nevertheless, we observe that existing protocols fail in fully utilizing the differences of the three types of tags. Therefore, this paper proposes a novel protocol, Durable Tree Slotted ALOHA-based protocol (DTSA), to further improve the efficiency obtained in the literature. In general, DTSA distinguishes the three types of tags based on the obtained information from the last identification process. Moreover, DTSA promptly resolves the collisions for the arriving tags and identifies the dwelling tags one-by-one without any collisions. Evaluation results justify that DTSA is more efficient than state-of-the-art protocols.

One fundamental and significant issue for large-scale radio frequency identification (RFID) systems is to promptly identify the missing events of passive tags. To this end, this letter proposes two novel protocols, Tag Retardation-based Compact Protocol (TRCP) and Probabilistic Prediction-based Protocol (P3), which address the missing-tag identification problem in a more time-efficient way than existing work. TRCP conducts tag retardation to alleviate tag collisions and achieve compact tag transmissions. Due to the fact that it is unnecessary to individually identify the tags that are likely to be missing simultaneously, we design P3, which leverages tag missing probability to avert needless tag retardation to further ameliorate TRCP. Simulation results validate the superiority of both TRCP and P3 to state-of-the-art studies in terms of time efficiency.

As an emerging approach in alleviating mobile data explosion, cognitive radio is adopted with diverse network models to promote wireless spectrum sharing between primary users (PUs) and secondary users (SUs). However, owing to PUs' priority, SUs may have to suspend their transmission before it is finished. Therefore, this letter considers the coexistence of cooperative cognitive radio networks and spectrum leasing markets which can offer SUs fixed transmission opportunity for their transmission. By adopting aspiration level to model SUs' behavior, we formulate SUs' strategy dynamics as a Discrete Time Markov Chain and illustrate the existence of stable state of the system under different cases through preliminary results. © 2012 IEEE.

Along with the speedy increase of cellular traffic due to new generation mobile devices, cellular network operators have been looking forward to offloading cellular traffic through WiFi networks. However, it is practically hard to satisfy both the operators and users in considering the poor coverage of current WiFi networks. Instead, WiFi tethering, which is a different way to provide WiFi networks, can solve this problem sufficiently and achieve mobile data offloading. This paper proposes a mobile tethering-based cooperative network which can make heterogeneous users gain certain profits after they participated in it. In the first stage of our system, each user's cellular traffic demand is allocated to others as a way which can minimize the total cellular traffic cost. According to this optimal resource allocation, the tethering price can be determined in the direction of maximizing total utility of all the participated users. Through the simulation results, we observed the reduction of total cellular traffic cost and found various optimal tethering prices in terms of different traffic demands. Although we made some assumptions in order to simplify our system model, it can be verified that it may also show an excellent performance in practice. © 2013 IEEE.
