Jamming in wireless sensor network Information technology essay
1 Introduction. The shared and open nature of the wireless communication medium of an underwater sensor network UWSN, 1 allows a malicious adversary to intelligently disrupt legitimate communications due to unfair channel access. Controllable reactive jamming is a realistic and highly damaging attack, where a jammer initiates its attack. This paper presents the concept and studies of federated deep reinforcement learning DRL-based anti-jamming communication in softwarization UAV network SUNET. Firstly, the task-driven SUNET framework is presented and a JBPC-based multi-domain anti-jaming model based on joint beamforming and power control is built to restore balance. When monitoring and detecting external communication data, wireless sensor networks are susceptible to interference from signals of different frequencies. To track the location of the jamming attack point and deploy a security defense mechanism, a minimal covered circle jamming attack localization algorithm based on the improved, using new methodologies such as Blockchain in data communication in wireless sensor networks WSN emerged as a result of the proliferation of collaborative technologies. However, the WSN is still vulnerable to denial-of-service cyber attacks, with jamming attacks becoming predominant in blocking data communications in the WSN; In this paper, we explore intelligent anti-jamming communication methods for wireless sensor networks. The stochastic game framework is introduced to model and analyze the multi-user anti. Wireless Sensor Networks WSNs have become the supporting infrastructure for new wireless technology trends such as Internet of Things IoT and Fog Computing over the years. Its application has spread into various fields, such as agriculture, the military, healthcare and home automation. The rise of. such as the Internet of Things IoT and Wireless Sensor Networks WSN, have led to a rethinking of network security methodologies and a reduction in operation and maintenance costs, especially at the physical layer, where energy consumption plays an important role; Wireless Sensor Networks WSNs are an increasingly valuable foundational technology for the Internet of Things IoT. is considered an increasingly important fundamental part of the IoT. The WSN market was worth $46 and is expected to be worth $126, with a CAGR of Abstract. Wireless sensor networks are built on a shared medium that makes it easy for adversaries to conduct radio interference or jamming attacks that effectively cause a denial of service. MULEPRO targets sensor network applications that require an immediate and robust response to such jamming-based DoS attacks and is designed to work with any number of channels. When an attack is launched, nodes can effectively coordinate exfiltration transmissions without having to exchange network protocol information. Summary - Wireless Sensor Networks WSNs are used in many networks. applications that often include monitoring and recording. of sensitive information. Therefore, their critical importance increases.
