“…Topologies of WSNs include the star, tree, mesh, hierarchical topologies, etc. Meshed networks are also known as “multi-hop” networks, in which nodes communicate in a many-to-many manner, with the advantages of redundancy and reliability [ 27 , 28 ]. The common mesh networking technologies include BLE mesh [ 29 ], WIFI mesh [ 13 ], and ZigBee mesh [ 27 ].…”

Wireless acoustic sensor networks (WASNs) and intelligent microsystems are crucial components of the Internet of Things (IoT) ecosystem. In various IoT applications, small, lightweight, and low-power microsystems are essential to enable autonomous edge computing and networked cooperative work. This study presents an innovative intelligent microsystem with wireless networking capabilities, sound sensing, and sound event recognition. The microsystem is designed with optimized sensing, energy supply, processing, and transceiver modules to achieve small size and low power consumption. Additionally, a low-computational sound event recognition algorithm based on a Convolutional Neural Network has been designed and integrated into the microsystem. Multiple microsystems are connected using low-power Bluetooth Mesh wireless networking technology to form a meshed WASN, which is easily accessible, flexible to expand, and straightforward to manage with smartphones. The microsystem is 7.36 cm3 in size and weighs 8 g without housing. The microsystem can accurately recognize sound events in both trained and untrained data tests, achieving an average accuracy of over 92.50% for alarm sounds above 70 dB and water flow sounds above 55 dB. The microsystems can communicate wirelessly with a direct range of 5 m. It can be applied in the field of home IoT and border security.

The Internet of Things technology transmits and shares physical information on the Internet, and describes the continuous world through scattered data. From the perspective of internal characteristics, the efficient interconnection of large-scale heterogeneous network elements is composed of the Internet of Things and imported from abroad, so there has been a high degree of accumulation in foreign countries so far. In 1980, the United States proposed a virtual reality concept called VR for short. Embedded virtual VR technology usually uses equipment to close the user’s senses and temporarily isolate the user from the actual environment. This article also discusses the design of industrial products, the continuous development of big data, artificial intelligence, and additive material manufacturing technology to make the design methods and manufacturing processes of industrial products more scientific and systematic, and promote the diversity and precision of industrial product design. Social informatization plays an important role in all areas of digital technology design. Parametric design has changed the design thinking mode of designers and formed new design trends and styles. Taking the search for relationships and rules as the starting point of the design and the algorithm as the core content of the design are very different from traditional design ideas. The computer age has not only cultivated new styles but also cultivated new artistic design techniques for industrial products. Designers should strive to explore the potential functions of algorithm technology and focus on smarter and more logical design and production processes. In this paper, through the research of the Internet of Things technology and virtual VR, it is applied to the research of the artistic design method of industrial products, aiming to promote its better development.

“…WMSNs consist of a large number of embedded devices that are equipped with low power cameras. These camera nodes are able to retrieve multimedia content from the environment at variable rates and transmit the captured information through multi-hop communication to base station [3,4]. WMSNs have generated much interest in recent years, and it is predicted that WMSNs will become useful in our daily life [5][6][7].…”

Wireless multimedia sensor networks (WMSNs) are increasingly being deployed for surveillance and monitoring applications. WMSNs applications produce large amount of data, which require high transmission rates. An efficient and seamless delivery of multimedia services in WMSNs is still a challenging task. This article proposes an intelligent video surveillance platform (IVSP) for wireless multimedia sensor networks. IVSP presents the design of a networked system for joint rate control and error control of video over resource-constrained embedded devices. First, a combination of two different congestion indicators is introduced to differentiate between congestion levels and handle them accordingly. Second, a feedback-based rate controller is developed to maximize received video quality, in which sensor nodes can adaptively adjust their sending rates. Finally, a different retransmission mechanism for different packets is proposed. Lost packets can be stored temporarily and resend when free channel is available to avoid congestion. The core component of IVSP is an open source hardware platform, which is based on Raspberry Pi sensor nodes. IVSP is extensively evaluated on 7 Raspberry Pi sensor nodes. We present the results of 7-node real-world deployment of IVSP in a video surveillance application and show that it works well in long-term deployments.
