Wireless Sensor Networks Overview

Abstract

Wireless sensor networks have become widely used for their high accuracy, safety, and reliability, particularly in military applications where information is critical to victory. Chinese scholars have conducted research on wireless sensor technology, with the aim of reducing costs, meeting low power requirements, and adapting to environmental changes to enhance China's military strength. However, data transmission speeds are slower and signal strength weaker compared to wired networks due to physical and technical limitations, which may result in slower or even interrupted data and file transfer speeds. Despite these limitations, wireless sensor networks have played a critical role in China's reconnaissance system for collecting and processing information in the battlefield environment. The technical principles of wireless sensor networks involve a distributed sensing system with multiple nodes consisting of data collection, big data processing, information processing, and energy supply modules. The identification and tracking of battlefield targets rely on passive observation of objects in activity using acoustic vibration sensors. The development of wireless sensor networks is still ongoing, with problems including limited computing power, storage capacity, communication ability, and energy supply of sensor nodes, as well as the potential for information leakage during the transmission process.
