Low-power wide-area (LPWA) is a major communicaiton technology used in the Internet of Things (Io‘I’), Major sensor networks are constructed using original protocols specific to each LPWA standard and cannot communicate directly with devices connected to the Internet. To enhance the convenience of devices using LPWA, it is necessary to improve their interop-erability with Internet applications with TCP/IP. Previous study have enabled Single-hop TCP/IP communication over Private LoRa. In this study, we construct a multi-hop environment for TCP/IP communication over Private LoRa, and evaluate its performance using both UDP and TCP communication. Previous research has enabled one-to-one communication using UDP and TCP over a Private LoRa interface, an LPWA technology. This study leverages the characteristics of LPWA for ultra-long-distance transmission and implements TCP/IP communication in a multi-hop environment. This paper evaluates the performance of UDP and TCP on actual devices.

IoT-based acoustic data collection systems have been proposed for detecting anomalies in mechanical equipment. However, traditional systems using audible sound do not work well due to interference from various sound sources. To solve this problem, we have previously proposed an ultrasonic data collection system, but the clear and high-quality sound required for anomaly detection results in an increase in data volume. This paper proposes a method for extracting only the necessary frequency band based on the periodicity of the target signal, aiming to reduce the amount of data. Our experiments demonstrate that the proposed method efficiently determines the appropriate frequency band in which the characteristics of the target equipment appear, thereby enabling the amount of data to be reduced by more than 45%.

QUIC is a transport protocol that adds congestion control, retransmission control, and TLS to UDP. QUIC can use the same congestion control algorithms as TCP. In previous work, we have shown that communication performance becomes unfair concerning the buffer size of the shared bottleneck link of two flows, one using CUBIC and the other BBR congestion control algorithms within QUIC. In this study, we improve the communication fairness performance at different bottleneck link buffer sizes by using Round Trip Time (RTT) and Explicit Congestion Notification (ECN) to regulate congestion control aggressiveness when CUBIC and BBR compete within QUIC through actual experiments.

Video streaming makes most of Internet traffic nowadays, being transported over Hypertext Transfer Protocol/Transmission Control Protocol (HTTP/TCP). Being the predominant transport protocol, TCP stack performance in transporting video streams has become paramount, specially with regard to MultiPath Transport Control Protocol (MPTCP) innovation and multiple client device interfaces currently available. Recently, Low Orbit Satellite networks have become available as a way to cover remote locations where cellular coverage is spotty at best with Internet access. In this paper, we evaluate video streaming performance via cellular and LEO links. Such scenario is commonplace in geographical areas where cellular communication is unreliable, such as disaster and conflict torn situations. We provide an extensive analysis of Bottleneck Bandwidth and Round-trip propagation time (BBR) TCP variant, as well as CUBIC when transporting video streams over terrestrial cellular network (LTE) and LEO (Starlink) access networks. We use network performance level, as well video quality level metrics to characterize quality of multipath video streaming over TCP variants.

With the widespread Internet technologies, malware damage also spreads worldwide, making it necessary to address these issues urgently. In some cases, malware-infected terminals use the Domain Name System (DNS) when communicating with the Command and Control (C&C) servers to obtain information for attacks. The previous malware detection focuses on the DNS communication history of malware-infected terminals. However, this method has the problem of poor accuracy in detecting malicious domains when the analysis data is small. This paper proposes a malicious domain detection with the following improvements. The first improvement is adding information on response and time. The second improvement is shortening the query domain names to primary domain names. Further, the proposed method showed improvement in the experiment.

IEEE 802.11ah (11ah) is a wireless LAN standard using the 920 MHz band and is expected to be used in the IoT field as one of the Low Power Wide Areas (LPWAs). Many LPWAs share the 920 MHz band and are characterized by low transmission rates but long-range communication. Therefore, there is a high possibility of contending communication in the real-world environment. In this study, we clarify the characteristics of contending communications between 11ah and LoRa according to evaluating the performance using real devices.

LPWA (Low Power Wide Area) is expected to be a communication technology suitable for the Internet of Things (loT) because of its features. Since LoRa communication has a trade-off between communication range and transmission rate, performance is inherently varied depending on the surrounding environment. Therefore, to achieve stable and efficient communication performance, it is necessary to set appropriate parameters for LoRa depending on the communication environment between the base station and the terminal. We here propose a method for dynamic control of parameter settings based on reception statistics of beacons. The effectiveness of the proposed method is evaluated from the real experiments.

Cyber Physical System (CPS) is a system that accumulates information from physical space, analyzes them in cyberspace, and then feeds back the results. We aim to realize a Floating Cyber Physical System (F-CPS), a regionally distributed CPS. We have proposed a large-capacity spatio-temporal data retention system for delivering data and function (application) in the F-CPS. In a previous work, we proposed a data completeness-aware transmission control and evaluated it by simulation. However, considering the movement of obstacles and fluctuation of radio waves in the real environment, packet loss occurs frequently. Thereby, the system may not be able to have complete data and may not function. In this paper, we proposed a method to recover missing data using redundant packets and evaluated its impact on the entire system by testing it with actual equipment.

Spatio-temporal aware IoT applications need to deliver the Spatio-Temporal Data (STD), which depends on geographic location and time, to the users in real-time. We have proposed the STD retention system using crowds of vehicles to promote the immediate distribution and utilization of STDs in geographical proximity to the user. However, when the system retains a Large-size STD (LSTD) consisting of multiple packets such as videos and photos, the packet loss due to channel collisions should be suppressed for effective retention of an LSTD. In this paper, we propose a complementary data transmission control method with collision avoidance for LSTD retention and clarify the effectiveness of our proposed method by simulation.

QUIC is a secure, general-purpose transport protocol using congestion and retransmission controls on User Datagram Protocol (UDP). QUIC can use the same congestion control algorithms as Transmission Control Protocol (TCP). Thus, when communication between multiple terminals using QUIC competes, the performance of each terminal depends on the congestion control algorithm adopted by the terminal. In related works, the communication performance was evaluated by simulation when both CUBIC and BBR flows competed in TCP, and the results showed that each communication performance became unfair with the buffer size of the shared bottleneck link. In this study, we verify the communication performance at different bottleneck link buffer sizes when BBR and CUBIC compete through actual experiments.

IoT data includes Spatio-temporal data (STD) that is needed only at a specific time and place. In our previous research, we have proposed the STD data retention system (STD-RS), aiming to construct a novel architecture for STD distributing in a retention area by vehicles. However, since vehicles may distribute the STD in unexpected locations due to GPS errors or malicious behavior in a real environment. Therefore, we propose a reliability audit mechanism based on multi-layered blockchain managing and analyzing the history of STD distribution and vehicles' behavior in each retention area. Through simulation experiment, we demonstrated that our mechanism detects the malfunction of STD-RS effectively.

Low-power wide-area (LPWA) is a major communication technology used in the Internet of Things (IoT). However, since LPWA does not conform to the TCP/IP protocol stack and employs its own unique protocol, it is difficult for sensors equipped with LPWA I/F to connect to the Internet directly. In the present study, to realize general TCP/IP communication on LPWA networks, we construct a TCP/IP network over Private LoRa, and evaluate its communication performance. Moreover, we verify the feasibility of TCP/IP communication over LoRa by using a popular Internet application.

Some specific services for Internet of Things, such as real-time map and providing local weather information, depend strongly on geographical time and location. We refer to the data for such service as spatio-temporal data (STD). When STD is used in a query response system similar to conventional Internet services, users not only need to acquire data actively as required, they must also have functions for retrieving data available STD. Therefore, we propose an STD retention system that uses vehicles as information hubs (InfoHubs) for disseminating and retaining the data in a specific area. In our system, InfoHubs diffuse, maintain, and advertise STD over places and times where the STD are strongly dependent, thereby allowing users to receive such data passively within the specific area. Additionally, because STD are associated with a particular space, the system can reduce search costs. We also propose an adaptive transmission control method that each vehicle effectively operates its wireless resources autonomously and STD are retained and distributed efficiently. Finally, we evaluated our proposed method using simulations and clarified that our proposed system is capable of achieving a coverage rate of nearly 100% for STD while reducing the number of data transmissions compared to existing systems.

With the development and spread of IoT technology, various devices have been connected to networks. Some data generated from IoT devices depends on geographical location and time (Spatio-Temporal Data). The realization of an architecture for "local production and consumption of STDs" can contribute to location-dependent applications, and therefore we have proposed the STD retention system with vehicles. In our previous study, the vehicle controlled the data transmission probability according to the density of the neighboring vehicles in order to reduce the data transmissions. However, since this method requires all vehicles to transmit beacons, it suffers from the excessive beacon collision when the vehicle density becomes high. In this paper, we propose a data transmission control method that realizes STD retention without transmitting beacons. Our simulation results using Luxembourg model demonstrates that the proposed method can achieve high coverage rate while decreasing the number of data transmissions compared with the existing transmission method based on transmission probability control in real environments.

In IoT era, the growth of data variety is driven by cross-domain data fusion. In this paper, we advocate that “local production for local consumption (LPLC) paradigm” can be an innovative approach in cross-domain data fusion, and propose a new framework, geolocation-centric information platform (GCIP) that can produce and deliver diverse spatio-temporal content (STC). In the GCIP, (1) infrastructure-based geographic hierarchy edge network and (2) adhoc-based STC retention system are interplayed to provide both of geolocation-awareness and resiliency. Then, we discussed the concepts and the technical challenges of the GCIP. Finally, we implemented a proof-of-concepts of GCIP and demonstrated its efficacy through practical experiments on campus IPv6 network and simulation experiments.

The communications quality of content delivery networks (CDNs), which are geographically distributed networks that have been optimized for content delivery, deteriorates when interflow congestion conditions are severe. Herein, we propose an adaptive server and path switching scheme that is based on the estimated acquisition throughput of each path. We also provide simulation results that show our proposed method can provide higher throughput performance levels than existing methods.

With the development and spread of Internet of Things (IoT) technology, the number of devices connected to the Internet is increasing, and various kinds of data are now being generated from IoT devices. Some data generated from IoT devices depends on geographical location and time. We refer to such data as spatio-temporal data (STD). Since the “local production and consumption” of STD is effective for location-dependent applications, we have proposed a STD retention system using vehicles equipped with storage modules, computing resources, and short-range wireless communication equipment. In this previous system, each vehicle controls the data transmission probability based on the neighboring vehicle density in order to achieve effective data retention. However, since the overhead of beacon messages required for estimation of the neighboring vehicle density becomes a critical problem with the increase in the number of vehicles, thereby preventing the effective data retention. In this paper, we propose a new data transmission control method to realize effective and reliable STD retention without beacon. Simulation results showed that our proposed scheme can achieve effective data retention.

This paper presents the results of verification tests for the application of a 5th generation mobile communication system (5G) to an industrial robot control system, consisting of an industrial robot, a three-dimensional measurement sensor, and a robot controller. First, the configuration of the industrial robot control system to be used for testing was examined. Second, the 5G radio characteristics at two factories were measured. The radio interference to/from devices in operation in the factories and the human shield effect influencing the radio characteristics were also examined in these measurements. In factory automation, it is generally inevitable to spend a long time rearranging the components of the industrial robot control system. From the test results, it was confirmed that the time required could be greatly reduced by replacing wired communication lines with 5G capable systems.
