Informacje dodatkowe: 

Szymon Szott uzyskał stopień doktora habilitowanego w dyscyplinie telekomunikacja na Akademii Górniczo-Hutniczej w Krakowie w 2018 roku. Obecnie pracuje tam jako profesor uczelni. W 2013 r. był wizytującym badaczem na Uniwersytecie w Palermo (Włochy) i na Uniwersytecie Stanforda (USA). Jego zainteresowania zawodowe związane są z bezprzewodowymi sieciami lokalnymi (dostęp do łącza radiowego, zapewnianie QoS, bezpieczeństwo). Jest autorem ponad 70 publikacji naukowych.

Additional information: 

Szymon Szott received his MSc and PhD degrees in telecommunications (both with honors) from the AGH University of Science and Technology, Krakow, Poland in 2006 and 2011, respectively. Currently he is working as an associate professor at the Department of Telecommunications of AGH University. In 2013, he was a visiting researcher at the University of Palermo (Italy) and at Stanford University (USA). His professional interests are related to wireless local area networks (channel access, quality of service, security, inter-technology coexistence). In the past, he has been a member of ETSI’s Network Technology Working Group Evolution of Management towards Autonomic Future Internet (AFI), a senior member of IEEE, an IEEE 802.11 Working Group member, and on the management board of the Association of Top 500 Innovators. He is a reviewer for international journals and conferences. He has been involved in several European projects (DAIDALOS II, CONTENT, CARMEN, MEDUSA, FLAVIA, PROACTIVE, RESCUE) as well as grants supported by the Ministry of Science and Higher Education and the National Science Centre. He is the author or co-author of over 70 research papers.

Summary: 
Quality of Service (QoS) is usually provided in ad hoc networks using a class-based approach which, without dedicated security measures in place, paves the way to various abuses by selfish stations. Such actions include traffic remapping attacks (TRAs), which consist in claiming a higher traffic priority, i.e., false designation of the intrinsic traffic class so that it can be mapped onto a higher-priority class. In practice, TRAs can be executed in IEEE 802.11 ad hoc networks using the Enhanced Distributed Channel Access (EDCA) function. This attack is easy to perform yet hard to prevent. We propose a distributed discouragement scheme based on the threat of TRA detection and punishment. The scheme does not rely on station identities or a trusted third party, nor does it require tampering with the MAC protocol. We analyze an arising non-cooperative TRA game and find that under certain realistic assumptions it only incentivizes TRAs if they are harmless to other stations; otherwise the selfish stations are induced to learn that TRAs are counterproductive.
