• Traffic Remapping Attacks in Ad Hoc Networks

  Publikacja

  • J. Konorski
  • S. Szott

  - IEEE COMMUNICATIONS MAGAZINE - Rok 2018

  Ad hoc networks rely on the mutual cooperation of stations. As such, they are susceptible to selfish attacks that abuse network mechanisms. Class-based QoS provisioning mechanisms, such as the EDCA function of IEEE 802.11, are particularly prone to traffic remapping attacks, which may bring an attacker better QoS without exposing it to easy detection. Such attacks have been studied in wireless LANs, whereas their impact in multihop...

• The Transmission Protocol of Sensor Ad Hoc Networks

  Publikacja

  • A. Marczak

  - Rok 2015

  This paper presents a secure protocol for a radio Ad Hoc sensor network. This network uses the TDMA multiple access method. The transmission rate on the radio channel is 57.6 kbps. The paper presents the construction of frames, types of packets and procedures for the authentication, assignment of time slots available to the node, releasing assigned slots and slots assignment conflict detection.

• Discouraging Traffic Remapping Attacks in Local Ad Hoc Networks

  Publikacja

  • J. Konorski
  • S. Szott

  - IEEE TRANSACTIONS ON WIRELESS COMMUNICATIONS - Rok 2014

  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...

• A framework for detection of selfishness in multihop mobile ad hoc networks

  Publikacja

  • J. Konorski
  • R. Orlikowski

  - Journal of Telecommunications and Information Technology - Rok 2009

  The paper discusses the need for a fully-distributed selfishness detection mechanism dedicated for multihop wireless ad hoc networks which nodes may exhibit selfish forwarding behaviour. The main contribution of this paper is an introduction to a novel approach for detecting and coping with the selfish nodes. Paper describes a new framework based on Dempster-Shafer Theory called Dempster-Shafer Theory-based Selfishness Detection...

• Distributed reputation system for multihop mobile ad hoc networks

  Publikacja

  • J. Konorski
  • R. Orlikowski

  - Rok 2008

  Zaproponowano system reputacyjny dla bezprzewodowej sieci rozległej ad hoc, pozwalający stacjm sieci zachować tzw. anonimowość pakietową oraz odróżniać zachowania niekoperacyjne od efektów przeciążenia sieci. Zastosowano generację miar reputacyjnych przy wykorzystaniu mechanizmu lokalnego nasłuchiwania (watchdog). Przeprowadzono symulacyjne badania odporności tego systemu na obecność stacji niewspółpracujących.

• Deep Learning-Based Intrusion System for Vehicular Ad Hoc Networks

  - CMC-Computers Materials & Continua - Rok 2020

  The increasing use of the Internet with vehicles has made travel more convenient. However, hackers can attack intelligent vehicles through various technical loopholes, resulting in a range of security issues. Due to these security issues, the safety protection technology of the in-vehicle system has become a focus of research. Using the advanced autoencoder network and recurrent neural network in deep learning, we investigated...

• An incentive-based forwarding protocol for mobile ad hoc networks with anonymous packets

  Publikacja

  • J. Konorski

  - Rok 2007

  Przekazywanie pakietów w sieciach ad hoc z transmisją wieloetapową zależy od współpracy ruchomych terminali oraz stworzenia właściwego systemu motywacyjnego. Zaproponowany protokół wykorzystuje elementy podejścia systemu reputacyjnego dla stworzenia funkcji wypłaty w grze niekooperacyjnej, w której strategie dotyczą konfiguracji progu admisji pakietów źródłowych w stacjach. Dla symetrycznego modelu sieci pokazano, że istnieją punkty...

• Dempster-shafer theory-based trust and selfishness evaluation in mobile ad hoc networks

  Publikacja

  • J. Konorski
  • R. Orlikowski

  - Rok 2009

  The paper addresses the problem of selfishness detec-tion in mobile ad hoc networks. It describes an approach based on Dempster-Shafer theory of evidence. Special attention is paid to trust evaluation and using it as a metric for coping with (weighted) recommendations from third-party nodes. Efficiency and robustness of the pre-sented solution is discussed with an emphasis on resil-iency to false recommendations.

• Nodal cooperation equilibrium analysis in multi-hop wireless ad hoc networks with a reputation system

  Publikacja

  • J. Konorski
  • K. Rydzewski

  - Rok 2017

  Motivated by the concerns of cooperation security, this work examines selected principles of state-of-the-art reputation systems for multi-hop ad hoc networks and their impact upon optimal strategies for rational nodes. An analytic framework is proposed and used for identification of effective cooperation-enforcement schemes. It is pointed out that optimum rather than high reputation can be expected to be sought by rational nodes.
