The Internet Of Things

The Internet of Things (IoT) technology is an information technology developed in recent years with the development of electronic sensors, intelligence, network transmission and control technologies. This is the third revolution in the development of information technology. This article aims to study the algorithm of the Internet of Things technology, through the investigation of the hazards of athletes’ sports training, scientifically and rationally use the Internet of Things technology to collect data on safety accidents in athletes’ sports training, thereby reducing the risk of athletes’ sports training and making athletes better. In this article, the methods of literature research, analysis and condensing, questionnaire survey, theory and experiment combination, etc., investigate the safety accident data collection of the Internet of Things technology in athletes’ sports training, and provide certain theories and methods for future in-depth research practice basis. The experimental results in this article show that 82% of athletes who are surveyed under the Internet of Things technology will have partial injuries during training, reducing the risk of safety accidents in athletes’ sports training, and better enabling Chinese athletes to achieve a consistent level of competition and performance through a virtuous cycle of development.

Network Flooding

Internet of Things (IoT) facilitates a wide range of applications through sensor-based connected devices that require bandwidth and other network resources. Enhancement of efficient utilization of a heterogeneous IoT network is an open optimization problem that is mostly suffered by network flooding. Redundant, unwanted, and flooded queries are major causes of inefficient utilization of resources. Several query control mechanisms in the literature claimed to cater to the issues related to bandwidth, cost, and Quality of Service (QoS). This research article presented a statistical performance evaluation of different query control mechanisms that addressed minimization of energy consumption, energy cost and network flooding. Specifically, it evaluated the performance measure of Query Control Mechanism (QCM) for QoS-enabled layered-based clustering for reactive flooding in the Internet of Things. By statistical means, this study inferred the significant achievement of the QCM algorithm that outperformed the prevailing algorithms, i.e., Divide-and-Conquer (DnC), Service Level Agreements (SLA), and Hybrid Energy-aware Clustering Protocol for IoT (Hy-IoT) for identification and elimination of redundant flooding queries. The inferential analysis for performance evaluation of algorithms was measured in terms of three scenarios, i.e., energy consumption, delays and throughput with different intervals of traffic, malicious mote and malicious mote with realistic condition. It is evident from the results that the QCM algorithm outperforms the existing algorithms and the statistical probability value “P” < 0.05 indicates the performance of QCM is significant at the 95% confidence interval. Hence, it could be inferred from findings that the performance of the QCM algorithm was substantial as compared to that of other algorithms.

This research was carried out according to the actual needs of plateau kitchen vehicle. However, these military equipments have played important roles in the military exercises, earthquake relief, and other major activities, they does need urgent improvements in the using process. Among those problems to be solved, drift distortion of pressure cooker signal transmission on account of low temperature of high altitude, inability of achieving accurate control, and untimely feedback of service demand included. The pressure automatic control system of plateau kitchen vehicle which is based on Single Carrier Ultra Wide Band (UWB) wireless technology (SC-UWB), will completely solve the above problems, and the followings are innovations of this study: Firstly, Single-carrier ultra-wideband wireless transmission technology was used in this study, which was in accordance with Chinese Standard and based on chips produced by China. This would satisfy the needs of real-time transmission in pressure and temperature information under extreme environment, and solve technical problems such as signal integrity and communicational confidentiality, and this would also eliminate technical problems such as signal distortion, hysteresis, drift, high deviation repeatability of automatic control system of plateau kitchen vehicle in extreme environment. Secondly, intelligent sensor systems were connected to the Internet of things (IOT). To develop Industrial Personal Computer (IPC) according to the management system and daily use of this equipment and to lead the equipment to have node function of access to the Internet of things, would be the foundation of all kinds of beneficial exploration in the management of Internet of things, and also the guarantee of technology standard of Internet of things in military equipment of future. Then, the existing equipment can smoothly be switched in to avoid duplication of investment.

With the popularization of the Internet-of-Things, various applications have emerged to make life easier. These applications generate a large amount of user data. Analyzing the data obtained from these applications, one can infer personal information about each user. Considering this, it is clear that ensuring privacy in this type of application is essential. To guarantee privacy various solutions exist, one of them is UbiPri middleware. This paper presents a decentralized implementation of UbiPri middleware using the Ethereum blockchain. Smart contracts were used in conjunction with a communication gateway and a distributed storage service to ensure users privacy. The results obtained show that the implementation of this work ensures privacy at different levels, data storage security, and performance regarding scalability in the Internet of Things environments.
