Design and Testing of an Arduino-based Network Jammer Device

A computer network is described as two or more devices connecting and communicating, each known as a computer network. These types of networks work on wired and wireless mediums. A sort of transmission medium is wired communications, also referred to as directed media. This form of communication is more reliable than wireless since it is the most stable. In wired communication, twisted pair cable, coaxial cable, and fiber optic cable are used to send data from the source to the destination. Wireless communication is also called “unguided” or “unrestricted” transmission media. In this mode, no physical medium is required to transmit electromagnetic signals. On the other hand, in wireless communication, a message can transfer through the air, water, or vacuum, i.e., infrared, radio, and microwave waves. Therefore, this research mainly focuses on wireless communication using radio frequency technology. This technology is also used on TVs, radios, laptops, modems, mobile phones, and pagers. People constantly interact with this technology in the modern world, and all these people have secure data and confidential information. However, in this case, someone uses this technology and tries to get the data illegally. It is a big problem for all civilians and the government. In this situation, a network jammer device can be used to protect those data from snooping attempts, location tracking, limiting cell phone activity, and cheating. This paper describes a low-cost network jammer that uses an Arduino and an RF 433 MHz module to create a frequency between 315 MHz and 433 MHz. It uses the denial-of-service technique to prevent illegal activities within a 100-meter range.
