Selfish Attacks in Two-hop IEEE 802.11 Relay Networks: Impact and Countermeasures
arXiv:1710.01006 · doi:10.1109/LWC.2018.2809726
Abstract
In IEEE 802.11 networks, selfish stations can pursue a better quality of service (QoS) through selfish MAC-layer attacks. Such attacks are easy to perform, secure routing protocols do not prevent them, and their detection may be complex. Two-hop relay topologies allow a new angle of attack: a selfish relay can tamper with either source traffic, transit traffic, or both. We consider the applicability of selfish attacks and their variants in the two-hop relay topology, quantify their impact, and study defense measures.
