Method for Preventing Selective Jamming Attacks Computer Science Essay
We address the problem of selective jamming attacks in wireless networks. In these attacks, the adversary selectively targets specific packets of high importance by using its knowledge. This article proposes four different jamming attack models that can be used by an adversary to disable the operation of a wireless network, and evaluates their effectiveness in terms of how each method affects a wireless node's ability to send and receive packets influences. Wireless networks are built on a shared medium that makes this possible. Various jamming techniques and types of jammers are discussed and some countermeasures that, if used, depending on the application, can significantly reduce the chances and effects of jamming are listed. Wireless sensor network is a collection of different nodes in a network that can share information via a wireless medium. Because of, Summary. Defending against jamming attacks is an increasing concern for the military and disaster response authorities. The military uses jamming attacks as a tool to target and disrupt terrorist communications because the open nature of wireless networks makes them vulnerable to various attacks. Many studies and some studies, Methods for Preventing Selective Jamming Attacks, by Pavani G. 15, start with an explanation of selective jamming attacks, and how they are an improved version of jamming. Experimental results show that the smart selective jamming attacks increase the probability of network reliability without triggering network updates, and this serious, insidious threat to WirelessHART networks is identified. As a leading industrial wireless standard, WirelessHART has been widely implemented to build wireless sensors. A new method is proposed to prevent the selective jamming attack in an internal threat model based on the technique called Strong Hiding Commitment Scheme SHCS, which prevents the jamming activity. of the jammer by encrypting the source ID of the message along with the message packet. The wireless networks are more susceptible to Marco Tiloca et al. 7 analyzed a specific selective jamming attack where the adversary detects jamming based on the technique called JAMMY, a distributed and dynamic solution for selective jamming in TDMA-based WSN. The technique takes into account the change in slot usage pattern with each superframe, providing a new method for preventing selective jamming attacks in wireless networks. IJMER Abstract Efficient Routing in Mobile Ad Hoc Networks MANETs are a challenging task due to varying physical channel characteristics, dynamic topology and non-centralized communication. The main documented method for conducting DoS attacks in LoRaWAN is through the use of signal jamming and replay attacks. Aras et al. 30 focused on the effect that the Spreading Factor plays in jamming devices on a LoRaWAN, but limited the attacks to a device transmitting over a single channel. The International Journal of Computer Engineering in Research Trends IJCERT is a peer-reviewed, open access journal that publishes high-quality research papers, reviews, short communications and notes in the field of computer engineering and its research trends. The journal covers a wide range of topics: it provides an overview of existing techniques for preventing jamming attacks and presents three schemes that provide real-time,
