Jamming in wireless networks with cooperative jammers
نویسنده
چکیده
The problem of jamming plays a very important role in ensuring the quality and security of wireless communications, especially now when wireless networks are quickly becoming ubiquitous. Since jamming phenomenon can be considered as a game where a player (say, jammer) is playing against a user (transmitter), game theory is an appropriate tool for dealing with the jamming problem. In this paper we study how increasing number of jammers impacts the game. Namely, we consider plots with M jammers and as an objective function to the user we consider SINR and Shannon capacity. For both objective functions we have shown that the jammers employ time sharing strategies to bring the maximal harm and we produce a finite step algorithm allowing to find the saddle point in closed form.

Alibi: A framework for identifying insider-based jamming attacks in multi-channel wireless networks
We consider the problem of identifying the insider-based attacks in the form of jammers in multi-channel wireless networks, where jammers have the inside knowledge of frequency hopping patterns and any protocols used in the wireless network. While this type of attackers is dangerous, most of current state-of-the-art jamming detection solutions cannot cope with them. In this work, we propose a n...

متن کاملJamming and anti-jamming techniques in wireless networks: a survey
Because of the proliferation of wireless technologies, jamming in wireless networks has become a major research problem due to the ease in blocking communication in wireless networks. Jamming attacks are a subset of denial of service (DoS) attacks in which malicious nodes block legitimate communication by causing intentional interference in networks. To better understand this problem, we need t...
متن کاملOn Performance Analysis of Protective Jamming Schemes in Wireless Sensor Networks
Wireless sensor networks (WSNs) play an important role in Cyber Physical Social Sensing (CPSS) systems. An eavesdropping attack is one of the most serious threats to WSNs since it is a prerequisite for other malicious attacks. In this paper, we propose a novel anti-eavesdropping mechanism by introducing friendly jammers to wireless sensor networks (WSNs). In particular, we establish a theoretic...
متن کاملLocalization and Routing against Jammers in Wireless Networks
Jammers are the devices that disturb the communication in wireless networks. If the actual position of jammer is located then it is possible to eliminate the disturbances in communication networks. This project designs a framework to locate the position of a single or multiple jammers more accurately. Many present jammer localizing schemes use indirect methods considering the hearing ranges, pa...
