This paper studies Wireless Information-Theoretic Security for low-speed mobility in autonomic networks. More specifically, the impact of user movement on the Probability of Non-Zero Secrecy Capacity and Outage Secrecy Capacity for different channel conditions has been investigated. This is accomplished by establishing a link between different user locations and the boundaries of information-theoretic...
The characteristics of Wi-Fi networks and their ever-growing popularity make them an obvious target for attacks. While intrusion detection systems have been popular in wired networks for a long time, their wireless equivalents are very limited. Anomaly-based detection methods have received an increasing interest by the scientific community in the last years. They are able to fight attacks without...
Multicasting and Broadcasting are important communication techniques in wireless adhoc networks to disseminate control messages and other important information during emergencies, battlefield operations, disaster relief efforts, etc. In this paper we propose an adaptive multi-source broadcasting protocol using Random Linear Network Coding. One key feature of this protocol is its multi-source operation,...
Jamming attacks have been recently studied as wireless security threats disrupting reliable RF communication in a wireless network. By emitting noise-like signals arbitrarily on the shared wireless medium, a jammer can easily disturb the network. Countermeasures such as Frequency-Hopping Spread Spectrum enable nodes to avoid the jamming attacks by hopping over multiple channels. However, these solutions...
