Demo: a testbed to evaluate frequency-hopping anti-jamming techniques in ieee 802.11
WiNTECH '14: Proceedings of the 9th ACM international workshop on Wireless network testbeds, experimental evaluation and characterizationPages 85–88https://doi.org/10.1145/2643230.2643244Wireless communication is inherently prone to disruption by interference. Frequency Hopping (FH) can counter interference and promises to enable communication again even in the presence of intentional interference by jammers. Evaluations of this anti-...

A real-time and protocol-aware reactive jamming framework built on software-defined radios
SRIF '14: Proceedings of the 2014 ACM workshop on Software radio implementation forumPages 15–22https://doi.org/10.1145/2627788.2627798This paper develops a software-defined radio (SDR) framework for real-time reactive adversarial jamming in wireless networks. The system consists of detection and RF response infrastructure, implemented in the FPGA of a USRP N210 and designed to ...

Gaining insight on friendly jamming in a real-world IEEE 802.11 network
WiSec '14: Proceedings of the 2014 ACM conference on Security and privacy in wireless & mobile networksPages 105–116https://doi.org/10.1145/2627393.2627403Frequency jamming is the fiercest attack tool to disrupt wireless communication and its malicious aspects have received much attention in the literature. Yet, several recent works propose to turn the table and employ so-called friendly jamming for the ...

Detection of reactive jamming in DSSS-based wireless networks
WiSec '13: Proceedings of the sixth ACM conference on Security and privacy in wireless and mobile networksPages 43–48https://doi.org/10.1145/2462096.2462104We propose a novel approach to detect reactive jammers in direct sequence spread spectrum (DSSS) wireless networks. The key idea is to use the chip error rate of the first few jamming-free symbols at the DSSS demodulator during the signal synchronization ...

WiFire: a firewall for wireless networks
SIGCOMM '11: Proceedings of the ACM SIGCOMM 2011 conferencePages 456–457https://doi.org/10.1145/2018436.2018518Firewalls are extremely effective at enforcing security policies in wired networks. Perhaps surprisingly, firewalls are entirely nonexistent in the wireless domain. Yet, the need to selectively control and block radio communication is particularly high ...

Short paper: reactive jamming in wireless networks: how realistic is the threat?
WiSec '11: Proceedings of the fourth ACM conference on Wireless network securityPages 47–52https://doi.org/10.1145/1998412.1998422In this work, we take on the role of a wireless adversary and investigate one of its most powerful tools---radio frequency jamming. Although different jammer designs are discussed in the literature, reactive jamming, i.e., targeting only packets that are ...

Detection of reactive jamming in sensor networks
ACM Transactions on Sensor Networks (TOSN), Volume 7, Issue 2Article No.: 16, Pages 1–29https://doi.org/10.1145/1824766.1824772An integral part of most security- and safety-critical applications is a dependable and timely alarm notification. However, owing to the resource constraints of wireless sensor nodes (i.e., their limited power and spectral diversity), ensuring a timely ...
