Performance Analysis of Parameters for UWSN (Underwater Wireless Sensor Network)

Abstract

The potential of underwater wireless sensor networks (UWSNs) for practical uses, including oil monitoring, deep sea archaeology, marine surveillance, and sea monitoring, is making them more and more popular among researchers. Since water covers about 70% of the Earth’s surface, it is difficult for people to extract useful information from the seafloor without the use of sophisticated equipment. Sensor nodes are positioned to sense the underwater environment in UWSNs. The data gathered is subsequently transmitted to a sink node, which forwards it to a base station for processing. Sensor node deployment in UWSNs is challenging because of the challenging underwater environment, and data routing is made more challenging by the nodes' high energy consumption and short communication range. Malicious nodes can use a variety of techniques, such as wormhole, black hole, and sybil attacks, to compromise UWSNs. The focus of lightweight cryptography is on algorithms that utilise less memory, computing power, and energy, which makes them appropriate for devices with limited resources, such as mobile phones, sensors, and Internet of Things devices. In lightweight cryptography, the chaotic system known as the Hénon map is occasionally employed, especially for text/image encryption. For devices with limited computing power, it can be used to create random sequences for encryption techniques' permutation and diffusion, providing a balance between security and resource efficiency.
